标准摘要
This document establishes a system of designation for thermoplastic polyurethane elastomers. The designation system can be used as the basis for specifications. The designation system is applicable to all thermoplastic polyurethane elastomers. It applies to materials ready for normal use in the form of powder, granules or pellets, unmodified or modified by colourants, fillers or other additives, etc. This document does not intend to imply that materials having the same designation give necessarily the same performance. This document does not provide engineering data, performance data, or data on processing conditions which might be required to specify a material for a particular application and/or method of processing. NOTE If such additional properties are required, they can be determined according to the test methods specified in ISO 16365-2, if suitable.
