What are the requirements of UL 2043 test for drive housing in the United States?

UL 2043 Standard name ：

UL 2043: Fire test for heat and visible smoke release for discrete products and their accessories installed in air-handling spaces

UL 2043: Fire test of individual separable products and their accessories used in air treatment places for heat and visible smoke release

UL 2043 Test summary ：

This is a fire test method , Used to determine the air handling space to be installed （ Such as above the ceiling ） Discrete products （ Electrical equipment ） Fire performance response . Place these products under an open flame ignition source , And use the product calorimeter for evaluation .

The purpose of this test is to comply with the national electrical code NFPA 70 The provisions of the , Determine the heat release rate and smoke release rate of the combustion product sample , Because they are related to the requirements of fire resistance and low smoke generation characteristics .

This test method does not provide information on the performance of the product under other fire or test conditions . This test does not investigate the toxicity of combustion products .

This test does not cover the structure of the product 、 Electrical or other performance requirements

UL 2043 Standard judgment basis ：

a) Peak heat release rate measured in each test (hrr) Should be less than or 100 kw .

b) The peak emission rate of flue gas measured in each test shall not exceed 0.21m2/s, SRRS.

c) Total smoke exhaust (10 Minutes test time ) No more than 75m2, TSR.
