Large Scale Mattress Fire Test | 16 CFR 1633 Open Flame Test The 1633 Large Scale Mattress Fire Test Equipment, in accordance with 16 CFR Part 1633, is used to measure the flammability performance of a mattress specimen by exposing a defined flaming source on its top and side in a controlled test chamber. All mattress sets defined in 16 CFR Part 1633.2(c) must pass the 1633 test before the sale or being introduced into commerce. The test sets two targets to limit the spread of flame on the mattress or mattress set, these are: the maximum heat release rate (HRR) from the mattress/mattress set must not exceed 200 kW during the 30-minute test period and the total heat release (THR) must not exceed 15 MJ during the first 10 minutes of the test. Exhaust Hood and Duct • A stainless steel made hood is installed out of the test room, the size is 2.44 meters by 2.44 meters. • The hood is used to collect the combustion gas and transfer to the exhaust pipe by the plenum chamber on the top. • The exhaust pipe is 406mm in diameter and 8 times diameter in length. • The hood and duct are connected to the exhaust system that capacity not less than 8,000 m3/h. Instrumental Section • The instrumental section is installed in the end of exhaust duct, equipped with thermocouples, differential pressure transducer, sampling probe, and white light system. • The flow sensor used in the exhaust duct is a bi-directional probe, the probes are made of 316 stainless steel. • The pressure transducer with a range of at least (0-200) Pa and an accuracy of ±2 Pa. Response time of 90% of the output of the pressure transducer is not more than 1s.
