This test is used to evaluate the sample being exposed to heavy impact forces perhaps caused by a person dropping themselves down into the seat. Each seating position will be tested separately for two drops. Each seating position not being tested will be loaded with 225 lb. of dead weight. For the first load load, 225 lb. will be dropped from 6 in. above the seat. For the second load, 300 lb. will be dropped from 6 in. above the seat.
