1 Scope
This part of ISO 16365 specifies the methods of preparation of test specimens and the standard test methods
to be used in determining the properties of thermoplastic polyurethane moulding and
extrusion materials. Requirements for handling test material and for conditioning
both the test material before moulding and the specimens before testing are also given.
Procedures and conditions for the preparation of test specimens in a specified state
and procedures for measuring properties of the materials from which these specimens
are given. Properties and test methods which are suitable and necessary to characterize
thermoplastic polyester/polyurethane and polyether/polyurethane (TPU) moulding and
extrusion materials, are listed.
The properties have been selected from the general test methods in ISO 10350. Other test methods in wide use or of particular significance to these moulding and
extrusion materials are also included in this part of ISO 16365, as are the designatory properties specified in ISO 16365‑1.
In order to obtain reproducible and comparable test results, it is necessary to use
the methods of preparation and conditioning, the specimen dimensions, and the test
procedures specified in this part of ISO 16365. Values determined are not necessarily identical to those obtained using specimens
of different dimensions or prepared using different procedures.
NOTE This part of ISO 16365 has been developed on the basis of ISO 10350‑1 as at the time of publication a standard on 'acquisition and presentation of comparable single point data' for thermoplastic elastomers' does not exist yet. After acceptance and publication of this part of ISO 16365, it is the intension to develop ISO 10350‑3, based on the two International Standards mentioned before, as starting point for the development of thermoplastic elastomer material standards.
