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.
sample :
Actual sample 1 individual
