This document does not provide engineering data, performance data or data on processing conditions which may be required to specify a material. If such additional properties are required, they are intended to be determined in accordance with the
47、test methods specified in ISO 20568-2, if suitable.In order to specify a thermoplastic material for a particular specification, the requirements are to be given in data block 5 (see 4.1).2 Normative referencesThe following documents are referred to in the text in such a way that some or all of their
