Nevada School Bus Law Incorporates Stringent Cal TB 133 Flammability Standards for Seat Cushions

The state of Nevada passed Senate Bill 318 effective July 1, 2011, which applies to school busses purchased on or after July 1, 2014, and requires that the flammability of the occupant seating must pass the equivalent of California's stringent TB 133 performance standard for upholstered furniture used in certain public occupancies.(ASTM E1537) This standard requires that no more than three pounds mass can be lost from the seat assembly subjected to the open flame test during the first 10 minutes, and the heat release rate must not exceed 80 kW. The bill also regulates the flammability of plastic components within the engine compartment in accordance with UL 94 (rating of V-O). View Bill Here
