This document specifies three methods for determining the shape retention properties and compression strength of a domed test specimen. These methods are the following and they are applicable to footwear toepuff and stiffener:Method 1: Applicable to heat activated materialsMethod 2: Applicable to solvent activated materialsMethod 3: Applicable to non-thermoplastic fibreboardNOTE Although it is usual to determine both the shape retention properties and the compression strength of a domed test specimen, either can be determined alone by carrying out the procedures relating to the respective property.
