Scope1.1 These test methods cover recognized methods for test-ing mattress innersprings, boxsprings, and finished mattressesor
3、 mattress sets, or both, to ensure uniformity of results.1.2 These test methods are applicable to un-upholsteredmattress core units including but not limited to innersprings, airchambers, and foam cores, un-upholstered foundations includ-ing but not limited to boxspring and build up foundations,fini
4、shed foundations and mattress constructions. Data devel-oped is for comparative analysis with no pass/fail criteriaapplicable.1.3 The durability test (Section 7), impact test (Section 8)and firmness retention test/surface deformation (Section 9)require upholstered samples. Firmness testing may be ra
