Certification and testing standards for LED lighting products exported to Europe and the United States

Nowadays, the lamps exported to Europe and the United States are mainly LED products. When it comes to LED standards, Chinese manufacturers say, Europe and the United States high demand for technical and safety standards are invisible technical barriers to trade. The industry believes that domestic LED lighting practitioners to break these technical barriers to overseas markets, first need to understand the European and American LED standards for LED lighting products, safety, electromagnetic compatibility, performance and other requirements.

  First, Europe and the United States the main standards bodies and certification mark

UL: UnderwriterLaboratoriesInc. abbreviation, UL safety testing institute is the most authoritative in the United States, but also in the world engaged in safety testing and identification of the larger civil institutions.

FCC:FederalCommunicationsCommission,isanindependentagencyoftheU.S.Government,directlyresponsibletoCongress.TheFCCcoordinatesdomesticandinternationalcommunicationsthroughthecontrolofradio broadcasting,television,telecommunications,satellitesandcable.

ETL: short for ETL ElectricalTestingLaboratories, ETL Laboratories was founded by American inventor Thomas Edison in 1896, and enjoys a high reputation in the United States and around the world. The "us" in the lower right indicates that it applies to the U.S., and the "c" in the lower left indicates that it applies to Canada, while both "us" and "c" are applicable in both countries.

EnergyStar: EnergyStar is a U.S. government-led energy conservation program for consumer electronics products. The EnergyStar program was launched in 1992 by the U.S. Environmental Protection Agency (EPA) to reduce energy consumption and greenhouse gas emissions from power plants.

IEC: International Electrotechnical Commission, is the world's earliest established international electrical standardization body, responsible for electrical engineering and electronic engineering in the field of international standardization work, the world's countries have nearly 100,000 experts in the development of standards to participate in the IEC, the revision of work.

ENEC: EuropeanNormsElectricalCertification, the European standard electrical certification is for specific and in line with European standards for products (such as lighting, components, and office & data equipment) used by the general European standard, ENEC mark is the European safety certification of the general mark, the beginning of the year 2000, the original only allowed European manufacturers to use "ENEC". In 2000, the "ENEC" mark was only allowed to be used by European manufacturers, and it is now open for use by all manufacturers in the world.

Second, LED products exported to the EU market standards

  Exported to the European Union countries need to be certified by including safety certification tests and electromagnetic compatibility certification tests, the main certification labeling CE and ENEC, certification standards mainly include: IEC/EN:60598-1 (general requirements and testing of lamps and lanterns), IEC/EN:60598-2-3 (road and street lighting fixtures and safety requirements), IEC/EN62031 ( LED module general safety requirements), IEC/EN62031 ( LED module general safety requirements), IEC/EN62031 ( LED module general safety requirements), IEC/EN62031 ( LED module general safety requirements), IEC/EN62031 ( LED module general safety requirements). General safety requirements for LED modules) IEC/EN:61000-3-2 (Limits for harmonic current emissions from equipment with single-phase input currents ≤16A),IEC/EN:61000-3-3 (Limits for voltage fluctuations and flicker in low-voltage power supply systems),IEC/EN61547 (Requirements for electromagnetic compatibility immunity of equipment used for general illumination),IEC/EN55015 ( Electrical lighting or type of equipment radio harassment characteristics of the limits and measurement methods).

 Third, LED products exported to the North American market standards

The main certifications for export to the North American market are UL, ETL, FCC and ENERGYSTAR, etc. LED road lighting products UL certification references UL8750 or UL60950, UL1598 two standards, do not test the lamps and lanterns of the EMC characteristics of the ETL certification test references are exactly the same as the UL standard.FCC certification references FCCPart15B, ClassAdigitaldevice. FCC certification references FCCPart15B, ClassAdigitaldevice test limit standards, do not test the safety characteristics of the lamps; ENERGYSTAT (ENERGY STAR) is mainly for residential and commercial lighting class LED lamps and lanterns photoelectricity performance requirements, LED road lighting is not listed.

FCC is the U.S. federal law of the radio harassment of teletext products (EMI) characteristics of the limit value of mandatory certification, LED lamps and lanterns of the FCC certification test and the European Union CE in the EMC certification test has a big difference, the main performance as follows:

1, LED lamps and lanterns of the FCC certification only test EMI, does not include EMS test items; CE in the electromagnetic compatibility test are two need certification test;

2, LED lamps and lanterns FCC certification is divided into ClassA and ClassB two categories, the two types of test limits are completely different, CE certification of radio harassment test limit standard only one, limit size and FCC ClassB equivalent;

3, LED lamps and lanterns FCC certification conducted harassment sweep test frequency from 0.15MHz to 30MHz end, CE certification in the conducted harassment sweep test frequency from 9KHz to 30MH end;

4, LED lamps and lanterns FCC certification space radiation harassment sweep test frequency from 30MHz to 1GHz end, CE certification in the space radiation harassment sweep test frequency from 30KHz to 300MH end;

5, FCC certification requirements are more demanding, its EMI certification test limit standards usually require a margin of 6dB or more, CE certification of EMI test margin of 3dB or more can be;

U
  In the UL certification of LED lighting products, drive power certification test can choose UL1310 or UL60950. the main differences between the two standards are as follows:

1, UL1310 is CLASSII (provide limited voltage and capacity of the power supply) power supply equipment safety standards, through the UL1310 certified power supply for the CLASSII power supply, the use of CLASSII power supply to do the cUL (Canadian market) certification of LED lighting fixtures can be exempted from the relevant safety tests; UL60950 is information technology class (referred to as IT) equipment UL60950 is the information technology class (referred to as IT) equipment safety standards, the scope of its applicable certification is greater than UL1310, but the use of UL60950 certified power supply to do cUL (Canadian market certification) LED lighting certification, not exempted from the relevant safety tests;

2, UL1310 standard output voltage under any load conditions in the power supply maximum output voltage (including no load) of the peak exposed contact voltage of 42.4V, when the equipment does not contain can be automatically in the output circuit disconnect device maximum output volt-ampere is not more than 100 volt-ampere; UL60950 is the definition of the output voltage under normal conditions, the voltage between any two touchable circuit parts, or The voltage between any two accessible circuit parts and the protective grounding terminal of Class I equipment does not exceed 42.4V AC peak, or 60V DC value;

3, UL1310 certification applies only to 120 or 240Vac nominal voltage in the grid CLASSII power supply equipment, UL60950 applies to the rated input voltage does not exceed 600Vac information technology products, for the 277V voltage system UL certification of LED lighting products drive power supply, can only refer to the UL60950 standard certification test.

UL certification

UL certification in the United States is a non-compulsory certification, mainly product safety performance testing and certification, the scope of its certification does not include product EMC (electromagnetic compatibility) characteristics. The following is a brief introduction to the LED road lighting products involved in UL8750, UL1310 and UL60950. UL8750 applies to the minimum safety requirements for LED lighting components that will be installed in non-hazardous locations rated at 600V branch circuit or lower, and the same applies to the minimum safety requirements for LED light sources connected to batteries, fuel cells, etc., isolated (no effective connection) power supply. UL1310 applies to CLASS2 power supply equipment that contains an input voltage of 120 or 240 Vac through software or direct plug-in connections to 15 or 20 A AC branch circuits or potentially less than 150 V grounded, that uses an insulated transformer and that can be incorporated into rectifiers and other components to provide DC or AC electrical energy, and that is intended to be used to provide energy for low-voltage electrical operations; UL60950 applies to safety standards for information technology (IT) equipment, including cell phones, computers and their peripherals, such as projectors, printers, etc., but also includes the output of the power supply can be taken with the LPS (restricted power supply) safety circuit;

In the UL certification of LED lighting products, drive power certification test can be used UL1310 or UL60950. the main differences between the two standards are as follows:

1, UL1310 is CLASSII (provide limited voltage and capacity of the power supply) power supply equipment safety standards, through the UL1310 certified power supply for the CLASSII power supply, the use of CLASSII power supply to do cUL (Canadian market) LED lighting fixtures certification, exemption from the relevant safety tests; UL60950 is information technology class (referred to as IT) equipment UL60950 is the information technology class (referred to as IT) equipment safety standards, the scope of its applicable certification is greater than UL1310, but the use of UL60950 certified power supply to do cUL (Canadian market certification) LED lighting certification, not exempted from the relevant safety tests;

2, UL1310 standard output voltage under any load conditions in the power supply maximum output voltage (including no load) of the peak exposed contact voltage of 42.4V, when the equipment does not contain can be automatically in the output circuit disconnect device maximum output volt-ampere is not more than 100 volt-ampere; UL60950 is the definition of the output voltage under normal conditions, the voltage between any two touchable circuit parts, or The voltage between any two accessible circuit parts and the protective grounding terminal of Class I equipment does not exceed 42.4V AC peak, or 60V DC value;

3, UL1310 certification applies only to 120 or 240Vac nominal voltage in the grid CLASSII power supply equipment, UL60950 applies to the rated input voltage does not exceed 600Vac information technology products, for the 277V voltage system UL certification of LED lighting products drive power supply, can only be cited as the UL60950 standard certification test.
