Certification IntroductionFDA (Food and Drug Administration) certification is a certificate of conformity for food or drugs issued by the U.S. Food and Drug Administration. Due to its scientific nature and rigor, this certification has become a world-recognized standard. FDA-approved drugs can be sold not only in the United States, but also in most countries and regions in the world. FDA is the English abbreviation of US Food and Drug Administration. It is an international medical review authority, authorized by the US Congress, the federal government, and the highest law enforcement agency specializing in food and drug management.The FDA is a monitoring agency of government health regulation composed of professionals such as doctors, lawyers, microbiologists, pharmacologists, chemists, and statisticians dedicated to protecting, promoting, and enhancing the nation's health. Foods, drugs, cosmetics and medical devices certified by the FDA are safe and effective for the human body. In nearly 100 countries such as the United States, only FDA-approved materials, devices and technologies can be used for commercial clinical applications.FDA classification1. FDA testing of food materialsPlastics, resins, rubbers, silicones, metals, alloys, electroplating, paper, cardboard, glass, ceramics, enamels, colorants, printing coatings, inks, etc.Food contact materials and products may affect the smell, taste and color of food during contact with food, and may release a certain amount of toxic chemical components such as heavy metals and toxic additives. Ingested by the human body, endangering human health.2. Food FDA testing 3. Medical device FDA testing 4. Cosmetics FDA testing 5. Drugs and biological products FDA testing application process1. Consultation---The applicant provides product information pictures or describes the products and materials that need to be applied for FDA through description. 2. Quotation---According to the information provided by the applicant, the technical engineer will make an evaluation to determine the items to be tested, 3. After the applicant confirms the quotation, fill in the test application form and test samples 4. Sample testing - the test will be carried out in accordance with the applicable FDA standards 5. After the test is completed, the FDA certification report will be providedAbout FDA certificateFDA registration actually adopts the good faith declaration model, that is: you are responsible for your products complying with relevant standards and safety requirements, and register on the US federal website.Does FDA registration have a certificate: In fact, all actions of FDA registration are done online, and there is no certificate. So what is the FDA certificate circulating on the market? In fact, it is a declarative document issued by the agency itself, proving that the product has been registered with the FDA.The difference between FDA certification, FDA testing and FDA registrationIt can be understood in this way that FDA testing generally targets these types of products: 1. Class II and III medical devices; 2. Cosmetics, daily necessities; 3. Food contact materials;FDA registration is generally divided into: 1. Cosmetics 2. LED and laser products 3. Medical devices 4. Food 5. DrugsFDA certification is a general term for FDA testing and FDA registration, both of which can be called FDA certification, and FDA certification is just a colloquial term.otherWhich agency issued the FDA certificate?There is no certificate for FDA registration. After the product is registered with the FDA, a registration number will be obtained. The FDA will give the applicant a confirmation letter (with the signature of the FDA chief executive), but there is no FDA certificate.Does the FDA require a designated accredited laboratory for testing?FDA is an enforcement agency, not a service agency. If someone says they are certified laboratories under the FDA, then he is at least misleading consumers, because the FDA has neither public service certification agencies and laboratories, nor so-called "designated laboratories". The FDA, as a federal law enforcement agency, cannot do this kind of thing as both a referee and an athlete. FDA will only recognize the GMP quality of service testing laboratories, and issue certificates of conformity to those who are qualified, but will not "designate" or recommend a specific one or a few to the public.Does FDA registration necessarily require a U.S. agent?Yes, Chinese applicants must designate a U.S. citizen (company/society) as their agent during FDA registration, who is responsible for process services located in the United States and is the medium between FDA and the applicant.

Certification IntroductionCEC certification is the Appliance Efficiency Regulation implemented by the California Energy Commission on December 30, 2005. The purpose of this regulation is to improve the efficiency of electrical products, save energy, reduce gas emissions and the greenhouse effect.The significance of CEC certificationWith more and more electronic products appearing in daily life, "saving energy" will become an urgent problem that everyone must face in the 21st century. The California Energy Commission (CEC) will implement a new mandatory standard for the energy efficiency of AC-DC and AC-AC external power supplies on July 1, 2006. At that time, almost all electronic products will be suffered an impact.The standard will cover all products that use external power supplies (such as chargers and adapters), including mobile phones, home wireless phones, portable music players, handheld game consoles, toys, etc., and requires these products to be in standby and in use. Use energy in a more efficient way.This means that after mid-2006, all transformers, external power supplies, adapters, and chargers used in the United States and sold to the United States will have to change their designs.In addition to saving energy, the CEC's new norm will also have a major impact on the environment. According to the company, if all California's external power supplies comply with the new standards, California will be able to reduce carbon dioxide emissions by more than 360,000 tons each year, an amount equivalent to the annual emissions of 60,000 cars.The regulation stipulates that electrical products must first meet the equipment energy efficiency regulations when they are sold in California, the regulation stipulates energy efficiency index requirements, measurement methods and phased implementation plans for 58 categories of electrical products. According to the requirements of this regulation, electrical products must be tested by a qualified laboratory in accordance with the corresponding regulations or standards in the United States, and they can only be sold in California after they prove that they meet the requirements.Applicable product scopeThe standard will cover all products that use external power supplies (such as chargers and adapters), including mobile phones, home wireless phones, portable music players, handheld game consoles, toys, etc., and requires these products to be in standby and in use. Use energy in a more efficient way. The definition range of CEC's external power supply is: single-phase voltage input AC/DC or AC/AC external power adapter.Application information1.

Product photos, instructions for use, safety matters or installation instructions, etc.Testing requirements⑴ Summary: Test adjustment, unless otherwise stated, are tested according to the following test conditions.⑵ Test instrument: The power measurement must be tested with a calibrated voltammeter or power analyzer. The instrument must be calibrated according to the standard of IEC 62301. When the test power is 0.5W, the error must be less than or equal to 2%. When the test power is less than 0.5W, the error must be less than 0.01W. The accuracy of the power test instrument must be 0.01W or better. The error of the tested voltage and current must be less than or equal to 2%.(3) Test room According to the standard requirements of IEC 62301, the air flow in the test room must be 0.5m/s or less, the ambient temperature must be controlled within the range of 23℃±5℃, and the sample must be placed on a test bench without heat conduction test on. Products for outdoor use, if there are additional testing requirements, must be stated in the report. ⑷ Test voltage According to the standard requirements of IEC 62301, the fluctuation range of the test voltage cannot exceed ±1% of the specified test voltage and ±1% of the specified test frequency. If the input voltage marked on the nameplate is a wide voltage, the test voltage is 115V/60Hz and 230V/50Hz. If the nameplate indicates a single voltage input, the test voltage is one of the two test voltages above. ⑸ According to the results, the California Energy Efficiency Law stipulates that from July 1, 2006, all external power supplies exported to California must meet the average energy efficiency regulations and no-load power requirements in the following table (see Table 1) and from January 1, 2008 Starting from No. 1, all external power supplies exported to California must meet the new average energy efficiency regulations and no-load power requirements in Table 2 below (see Table 2). All tests must take into account 100% of the output current indicated on the nameplate, 75%, 50%, 25% load conditions (note: the error range of the load here cannot exceed ±2%), record its input power, input current, power factor, output voltage, and THD (Total Harmonic Distortion) , and then according to energy efficiency = (output voltage × output current) / input powerto calculate the current energy efficiency value, and then average the energy efficiency values measured under the four load conditions of 100%, 75%, 50%, and 25% to obtain the average energy efficiency value. The average energy efficiency value and no-load power value obtained from the above tests are used to determine whether it meets the energy efficiency mark according to the limit requirements of TABLE1 and TABLE2.

Certification IntroductionNRTL refers to Nationally Recognized Laboratory, which is the abbreviation of Nationally Recognized Testing Laboratory in English. The Occupational Safety and Health Administration (OSHA) under the U.S. Department of Labor requires that products used in the workplace must be tested and certified by a nationally recognized laboratory. Ensure the personal safety of users. In North America, manufacturers who legally sell products for civilian or industrial use in the market must conduct rigorous testing in accordance with national standards. The product can only be legally sold in the market if it has passed the relevant tests of the Nationally Recognized Laboratory (NRTL). Nationally Recognized Testing Laboratories (NRTL) are third-party organizations that certify products for the North American market. NRTL is accredited by the Occupational Safety and Health Administration (OSHA) under 29 CFR1910.7 to provide safety testing and certification services for products used in workplaces in the United States. In Canada, only accreditation bodies accredited by the Standards Council of Canada (SCC) can carry out such services.NRTL agencyNRTL-MET Laboratory NRTL-UL Laboratory NRTL-CSA Laboratory NRTL-TUV Laboratory NRTL-NEMKO LaboratoryNRTL-ITS LaboratoryCertified product scopeThe authorized scope of each NRTL certification is different.

The technical certification officer issues the certificate. 5. Carry out regular factory supervision and follow-up to ensure the credibility of the certificate.NRTL meaningJust like China's CCC certification, it is a mandatory safety certification for products on the market in North America. However, unlike CCC certification, which is highly mandatory, and there is no unified certification logo, there are only 16 testing laboratories authorized by the US Occupational Safety and Health Administration (OSHA), and manufacturers legally sell domestic or industrial products in the market. The products used must be strictly tested according to the US national standards. NRTL certification is more helpful to improve the brand awareness of enterprises in related industries and markets in North America, and guide consumers to purchase products that meet the safety requirements. Through the structural inspection of the product and related tests, it can effectively protect the safety and health of consumers, increase customer satisfaction, and thus gain a larger market.

Certification IntroductionEnergy Star is an energy conservation program led by the U.S. government, mainly for consumer electronics. The ENERGY STAR program was launched in 1992 by the U.S. Environmental Protection Agency (EPA) and the U.S. Department of Energy (DOE) to reduce energy consumption and reduce greenhouse gas emissions. The scheme has since been adopted by Australia, Canada, Japan, Taiwan, New Zealand and the European Union. The program is voluntary, and ENERGY STAR standards are typically 20-30% more energy efficient than U.S. federal standards. The earliest products to cooperate with this plan are mainly computer and other information appliances, and then gradually extended to electrical machinery, office equipment, lighting, home appliances and so on. Later, it was extended to buildings. The US EPA has actively promoted the Energy Star Building Program since 1996. The EPA assists voluntary participants in evaluating the energy use status of their buildings (including lighting, air conditioning, office equipment, etc.), planning the building. The energy efficiency improvement action plan and follow-up work of things, so some residential or industrial and commercial buildings that have introduced new concepts of environmental protection can also find the ENERGY STAR logo.Development statusSeven countries and regions around the world have participated in the ENERGY STAR program promoted by the US EPA, namely the United States, Canada, Japan, Taiwan, Australia, New Zealand, and the European Union. Since 2001, the International Energy Star Program Conference has been held annually. Now the products included in the scope of this certification have reached more than 30 categories, such as household appliances, heating/cooling equipment, electronic products, lighting products, etc. Currently, lighting products, including energy-saving lamps (CFL), are the most popular in the Chinese market. , light fixtures (RLF), traffic lights and exit lights.Applicable product scopeComputers and office equipment: such as monitors, printers, fax machines, copiers, all-in-one machines, etc.; household appliances and similar household products: such as refrigerators, air conditioners, washing machines, televisions, video recorders, etc.; heating and cooling equipment: heat pumps, boilers, Central air-conditioning, etc.; large commercial buildings and newly built houses, doors and windows, etc.; industrial and commercial products, such as transformers, power supplies, etc.; lighting: such as household lamps, etc.; commercial food equipment: such as commercial ice cream machines, commercial dishwashers, etc.; others Commercial products: vending machines, channel signs, etc. Products currently targeted are: fluorescent lamps, decorative string lights, LED lamps, power adapters, switching power supplies, ceiling fan lights, consumer audio-visual products, battery charging equipment, printers, home appliances and a variety of other products.Test contentTest content included with ENERGY STAR:Safety, EMI, surge, noise (non-Energy Star energy efficiency test items) Optical performance and energy efficiency test items:1.

Switching cycle6. Luminous maintenance rate7. Chroma maintenance rate8. Size9. Electrical parametersENERGY STAR Residential ProgramThe EPA's ENERGY STAR Residential Program is a nationwide volunteer program to build a new type of home that is 30 percent more energy efficient. Eligible ENERGY STAR homes are subject to third-party verification that the builder has appropriately implemented energy efficiency measures. As long as they can see the ENERGY STAR logo, home buyers who are not experts can make purchasing decisions with confidence. In general, ENERGY STAR homes are 30% more energy efficient than homes built to common energy codes, while protecting the environment and saving occupants energy bills. The construction of ENERGY STAR homes benefits not only buyers but also builders, mortgage lenders and other organizations in the housing industry, so home builders across the country support the ENERGY STAR Residential Program. Homes are usually new construction because it is much simpler to build a home that complies with energy efficiency regulations than to renovate an existing home. While retrofitting a home to earn ENERGY STAR can be expensive, it can significantly reduce energy bills, so retrofitting an existing home with energy efficiency is still a good idea. When replacing air conditioning, electrical equipment or lighting, you should also consider purchasing products that bear the ENERGY STAR logo, which can further improve the energy efficiency of your home. The ENERGY STAR Residential Program uses the Residential Energy Rating System (HERS) to determine a home's energy efficiency score. Both new and existing homes must meet the same energy efficiency standards to receive the ENERGY STAR badge. In order to get a HERS assessment, or to seek a path to the ENERGY STAR mark, it is also necessary to consult a local qualified residential energy assessment agency to compare a model home (which is the same size and shape as the home being assessed and meets the minimum energy code requirements), the HERS evaluation system conducts objective and standard evaluations of residential energy efficiency. HERS assessment scores range from 0 to 100. The score for the model home is 80. Compared with the model house, every 5% reduction in energy consumption equals one point increase in HERS. The lowest HERS rating for an Energy Star home is 86. The HERS assessment includes on-site inspection of the residence. This inspection includes blower door testing and duct leak testing. The results of these tests, along with other information about the residence, are fed into a simulated computer program to calculate the HERS score and estimate the annual energy bill. Energy Efficient Windows ENERGY STAR Homes are equipped with high performance energy efficient windows that increase the energy efficiency of the home. Quieter indoor environment - multi-layer glazing and sealed window frames block external noise; prevent fading of curtains, furniture and floors - energy efficient windows are covered with a low reflectivity coating that blocks 98% of UV rays; lower operating costs - -Energy-saving windows make the house reduce heat loss in winter and prevent heat absorption in summer; quality improvement - energy-saving windows are made of high-quality materials, easy to use, and provide users with additional protection. Windows occupy about 10-25% of the exterior wall area of a house. Depending on the climate, it consumes 25-50% of energy when heating and cooling a room. Therefore, when building a new home, it is crucial to consider the use of energy efficient windows. Heating and Cooling Equipment ENERGY STAR homes are equipped with properly sized, efficient heating and cooling equipment. With proper attention to air duct sealing, home insulation, and energy efficient windows installed during home construction, heating and cooling equipment in ENERGY STAR homes is often less wattage than homes built to general energy codes. Lower cost of ownership - heating and cooling equipment does not need to be overloaded; less maintenance problems - heating and cooling equipment always operates at an optimal state; quieter home environment - no need to constantly and frequently switch over-power equipment. The lack of tight air and ventilation ducts means that the heating and cooling equipment of ordinary houses needs to be increased in power to quickly meet its cooling and heating requirements. But this kind of high-power equipment has great disadvantages: ① It cannot run for a long time to reach its most efficient operating level; ② When the system cannot run for a long time to remove moisture from the air, it leads to the problem of house humidity; ③High-power equipment often causes the equipment to be paralyzed quickly because of frequent startup. Tight air and ventilation ducts reduce the need for air-conditioning gas to heat and cool the home, thereby avoiding the need for high-power equipment. Improved Insulation ENERGY STAR homes have greatly improved insulation performance compared to those built to common energy codes. The improved thermal insulation not only prevents excess heat and cold from spilling out, but also maintains a constant temperature between rooms. Increased comfort - maintains a constant temperature throughout the home and between rooms. Lower cost of ownership - HAVC equipment compensates for the small amount of heat and cold exchange in the house in winter and summer. In order to effectively maintain the temperature of the house, continuous thermal insulation inside and outside is necessary. The insulation must be laid without cracks, curls or compressions. ENERGY STAR homes must also pay attention to thermal insulation around obstructions such as pipes, electrical wiring and outlets. Sealed ConduitENERGY STAR homes have significantly higher conduit tightness requirements than homes built to common energy codes. Sealed ducts are essential for saving energy and maintaining the comfort of your home. More sustained comfort—assignment to each room significantly improves indoor air quality—reduces room intake of dust and other pollutants from the outside world. Lower cost of ownership - reduce the need for air conditioning gas in the room. In a typical American home, 20-30% of the air leaks from the ducts, which means a lot of unnecessary money is spent to make the room warmer or cooler. Duct systems should be kept sealed and locally tested to reduce air-conditioning gas leakage. energy-efficient retrofitting existing homes can use the ENERGY STAR Residential Benchmark, an internet-based assessment tool, to compare the annual energy consumption of similar homes in their country. This tool helps owners of completed homes understand whether their homes meet energy efficiency requirements and whether they should upgrade their home energy efficiency measures to increase energy efficiency. On the ENERGY STAR website, the tool also helps owners of established homes quickly decide which home retrofit options to choose to improve energy efficiency. The ENERGY STAR Residential Program also offers a Residential Retrofit Toolkit to assist in energy-efficient retrofits in established homes. The average household spends 1,400 per year on energy use bills. The help of the "Home Improvement Toolkit" can reduce these expenditures by 30%, and almost 400 When repairing, rebuilding or improving an existing home, the energy saving measures in the "Home Improvement Toolbox" It helps homeowners improve the energy efficiency, value and comfort of their homes, and protects the environment by reducing energy consumption. For homeowners, the Home Improvement Toolkit makes home improvement and renovation projects easier.
