It applies to unmodified materials ready for normal use and materials modified, for example, by colorants, additives, fillers, reinforcing materials and polymer modifiers.It is not intended to imply that materials having the sa

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
