FM Global Reduced-Commodity Testing

A reduced-commodity test was developed by FM Global that captured the flammability characteristics inherent in a rack storage fire while limiting the total quantity of test commodity to approximately one pallet load per test due to the significant costs, as previously discussed. 

Thirteen reduced-commodity fire tests were conducted focusing on a comparison of the flammability characteristics of FM Global standard commodities and the three types of cartoned Li-ion battery products. All tests were free bum fire tests that measured the heat release rate and the evaluated time of battery involvement for the Li-ion products. Each test was conducted in a two by one by three high pallet load rack storage arrangement that represents storage up to 15 ft tall.
