13、oximately 200 - 250 mm x 75 mm with the longer dimension parallel to the roll direction and also 3 specimens across the roll direction. It is important that both the original sample and the individual test specimens are not folded or creased prior to testing. Bend the test specimen, without undue te
14、nsion or pressure around form A with the face side to the clear acrylic form. Inspect the specimen through the acrylic sheet for evidence of creasing or collapse of the laminate foam. If the specimen is acceptable on form A repeat the test on form B then C, or until evidence of creasing occurs. Report the identification letter of the test form with the smallest radius on which the majority of test specimens pass.
