Certification Introduction
CEC 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 certification
With 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 scope
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. The definition range of CEC's external power supply is: single-phase voltage input AC/DC or AC/AC external power adapter.
Application information
1. Product name: provide the full name of the product
2. Product model: list all the product models, varieties or classification numbers that need to be tested in detail
3. The intended use of the product: such as home, office, factory, coal mine, ship, etc.
4. Parts list: List the parts and models (classification numbers), ratings, and manufacturers that make up the product in detail. For insulating materials, please provide the name of the raw material.
5. Electrical properties: For electronic and electrical products, provide the point schematic diagram (circuit Figure), ingredient list, etc.
6. Structure diagram: For most products, the structure diagram or exploded diagram, ingredient list, etc. of the product should be provided
7. Product photos, instructions for use, safety matters or installation instructions, etc.
Testing requirements
⑴ 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 power
to 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.
