Lamps appliances certification
Currently, the lamps exported to Europe the United States are mainly LED products. When it comes to LED stards, for Chinese manufacturers, the high technical safety stards in Europe the United States are invisible technical trade barriers. The industry believes that if domestic LED lighting practitioners want to break these technical barriers enter overseas markets, they first need to underst the safety, electromagnetic compatibility, perance other requirements of European American LED stards for LED lighting products.
1. Major European American stards bodies certification marks
UL: is the abbreviation of Underwriter Laboratories Inc., the UL Safety Laboratory is the most authoritative in the United States the largest private institution engaged in safety testing identification in the world.
FCC: Federal Communications Commission (Federal Communications Commission) is an independent agency of the U.S. government, directly responsible to Congress. The FCC coordinates domestic international communications by controlling radio broadcasts, television, telecommunications, satellites cables.
ETL: ETL is the abbreviation of American Electronic Testing Laboratories. ETL Laboratory was founded by American inventor Edison in 1896 enjoys a high reputation in the United States around the world. The "us" in the lower right means that it applies to the United States, the "c" in the lower left means that it applies to Canada. Having both "us" "c" means it applies to both countries.
Energy Star: Energy Star is an energy conservation program led by the U.S. government, mainly targeting consumer electronics. The Energy Star program was launched by the U.S. Environmental Protection Agency (EPA) in 1992 with the purpose of reducing energy consumption Reduce greenhouse gas emissions from power plants.
IEC: International Electrotechnical Commission, is the earliest international electrotechnical stardization organization in the world. It is responsible for international stardization work in the fields of electrical engineering electronic engineering. Nearly 100,000 experts from all over the world participate in the ulation of IEC stards. Revision work.
ENEC: (EuropeanNormsElectricalCertification), European stard electrical certification is a common European stard used for products that are specific comply with European stards (such as lighting equipment, components, office & data equipment). The ENEC mark is a common European safety certification mark, 2000 The "ENEC" mark, which was originally only allowed to be used by European manufacturers, is now open to use by all manufacturers around the world.
2. Stards for exporting LED products to the EU market
Exports to EU countries need to pass safety certification testing (LVD) electromagnetic compatibility certification testing (EMC). The main certification marks are CE ENEC. The certification reference stards mainly include: IEC/EN:60598-1 (General requirements for lamps test), IEC/EN:60598-2-3 (Safety requirements for road street lighting fixtures), IEC/EN62031 (General safety requirements for LED modules) IEC/EN:61000-3-2 (single-phase input current ≤16A Equipment harmonic current emission limits), IEC/EN: 61000-3-3 (Limits of voltage fluctuations flicker in low-voltage power supply systems), IEC/EN61547 (Electromagnetic compatibility immunity requirements for general lighting equipment), IEC/EN: EN55015 (Limits methods of measurement of radio disturbance characteristics of electrical lighting or type equipment).
3. Stards for exporting LED products to the North American market
The main certifications exported to the North American market include UL, ETL, FCC ENERGYSTAR (Energy Star). The UL certification of LED road lighting products refers to two stards: UL8750 or UL60950 UL1598. The EMC characteristics of the lamps are not tested. The ETL certification test is quoted. Exactly the same as UL stards. FCC certification refers to the test limit stard of FCC Part 15B, Class A digital device, does not test the safety characteristics of lamps; ENERGYSTAT (Energy Star) mainly targets the photoelectric perance requirements of LED lamps for residential commercial lighting, LED road lighting is not included for the time being.
FCC is a matory certification for the radio interference (EMI) characteristic limits of telex video products stipulated by US federal law. The FCC certification test of LED lamps is quite different from the electromagnetic compatibility certification test in the EU CE. The main perances are as follows:
1. The FCC certification of LED lamps only tests EMI (radio interference) does not include EMS (radio anti-interference) test items; the electromagnetic compatibility test in CE requires certification testing for both items;
2. The FCC certification of LED lamps is divided into two categories: ClassA (LED lamps used in industrial commercial environments) ClassB (LED lamps used in residential environments). The test limits of the two categories are completely different. Radios in CE certification There is only one disturbance test limit stard, the limit value is equivalent to Class B in the FCC;
3. The conductive disturbance scan test frequency for FCC certification of LED lamps starts from 0.15MHz ends at 30MHz, the conductive disturbance scan test frequency for CE certification starts from 9KHz ends at 30MH;
4. The FCC certification space radiation disturbance scanning test frequency of LED lamps starts from 30MHz ends at 1GHz, the space radiation disturbance scanning test frequency in CE certification starts from 30KHz ends at 300MH;
5. FCC certification requirements are more stringent. Its EMI certification test limit stard usually requires a margin of more than 6dB. When the EMI test margin of CE certification is 3dB or more (including the margin after the reading point);
UL certification is a non-compulsory certification in the United States. It mainly tests certifies product safety perance. Its certification scope does not include the EMC (electromagnetic compatibility) characteristics of the product. The following is a brief introduction to LED road lighting products involving UL8750, UL1310 UL60950. UL8750 applies to the minimum safety requirements for LED lighting source components that will be installed in non-hazardous locations rated at 600V branch circuits or lower. It also applies to the minimum safety requirements for LED light sources connected to isolated (no effective connection) power sources such as batteries fuel cells. Requirements; UL1310 is applicable to 15 or 20A AC branch circuits containing input voltages of 120 or 240Vac connected via software or direct plug-in or potentially less than 150V to ground, using an isolating transer that may be incorporated into rectifiers other components to provide DC or AC energy. , is expected to be used to provide energy to CLASS2 power equipment operated by low-voltage electricity; UL60950 is applicable to the safety stards of ination technology (IT) equipment, including mobile phones, computers their peripheral equipment, such as projectors, printers, etc., Including power supplies whose outputs can be equipped with LPS (Limited Power Supply) safety loops;
In the UL certification of LED lighting products, UL1310 or UL60950 can be used for driving power certification testing. The main differences between the two stards are as follows:
1. UL1310 is a safety stard for CLASSII (power supply with limited voltage capacity) power supply equipment. The power supply certified by UL1310 is a CLASSII power supply. When using CLASSII power supply for cUL (Canadian market) LED lighting fixture certification, relevant safety tests can be exempted; UL60950 is a safety stard for ination technology (IT) equipment. Its applicable certification scope is larger than UL1310. However, when using a power supply certified by UL60950 for cUL (Canadian market certification) LED lighting fixtures certification, the relevant safety tests cannot be exempted. ;
2. The UL1310 stard stipulates that the maximum output voltage of the power supply under any load condition (including no load) has a peak exposed contact voltage of 42.4V. When the equipment does not contain a device that can automatically cut off the power in the output circuit, the maximum output volt-ampere is not more than 100 VA; UL60950 defines that under normal output voltage conditions, the voltage between any two accessible circuit components, or the voltage between any accessible circuit component the protective grounding terminal of Class I equipment, shall not exceed 42.4V AC peak value, or 60V DC value;
3. UL1310 certification is only applicable to CLASSII power supply equipment in the power grid with a calibrated voltage of 120 or 240Vac. UL60950 is applicable to ination technology products with a rated input voltage not exceeding 600Vac. For the driving power supply of UL-certified LED lighting products with a 277V voltage system, it can only be Quoted from UL60950 stard certification testing.
