ISO 20864:2004 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 materials method 2: applicable to solvent activated materials method 3: applicable to non-thermoplastic fibreboard
