2、 revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 These test methods cover nationally recognized methodsfor testing mattress innersprings and boxsprings to ensureuniformit

3、y of results.1.2 These test methods are applicable to un-upholsteredinnersprings and boxsprings only and are not applicable tofinished upholstered mattresses or boxsprings. Any conclusionscovering such items are outside the scope of these testmethods.1.3 The durability test (Section 7), impact test
