Scope: 1.1 These methods apply to slab flexible cellular foams known as urethane foam. Urethane foam may be generally defined as an expanded cellular product produced by the interaction of active hydrogen compounds, water, and isocyanates. NOTE 1—These methods have been developed primarily for slab foam. Tests for molded foam are covered in ASTM Methods D 2406, Testing Molded Flexible Urethane Foam.2 1.2 This document covers test procedures only. The numerical specifications will be developed as separate documents by appropriate groups based on end use, such as automotive, etc. 1.3 Unless specifically stated otherwise, between the vendor and the purchaser, all tests shall be made in accordance with the methods specified in Sections 5 to 101 which include test procedures for the following: Sections Basic Tests: Steam Autoclave Test 5 to 11 Constant Deflection Compression Set 12 to 18 Test Load Deflection Tests Method A, Indentation (to specified 19 to 25 deflections) Method B, Indentation (to specified 26 to 31 loads) Air Flow Test 32 to 38 Suffix Tests: Compression Load Deflection Test 39 to 44 (Suffix D) Dry Heat Test (Suffix A) 45 to 51 Fatigue Test (Suffix H) 52 to 68 Sections Density Test (Suffix W) 69 to 73 Tear Resistance Test (Suffix G) 74 to 80 Tension Test (Suffix T) 81 to 88 Resilience (Ball Rebound) Test (Suffix 89 to 94 R)
