1 Scope
This part of ISO 14910 specifies the methods of preparation of test specimens and the standard test methods
to be used in determining the properties of thermoplastic polyester/ester and polyether/ester
moulding and extrusion materials. Requirements for handling test material and/or for
conditioning both the test material before moulding and the specimens before testing
are 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 made are given. Properties and test methods which are suitable and necessary to
characterize thermoplastic polyester/ester and polyether/ester moulding and extrusion
materials are listed.
The properties have been selected from the general test methods in ISO 10350‑1. Other test methods in wide use for or of particular significance to these moulding
and extrusion materials are also included in this part of ISO 14910, as are the designatory properties specified in ISO 14910‑1 (hardness, melting temperature and tensile modulus).
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 14910. Values determined will not necessarily be identical to those obtained using specimens
of different dimensions or prepared using different procedures.
NOTE This part of ISO 14910 has been developed on the basis of ISO 10350‑1 as, at the moment, no standard exists for the acquisition and presentation of comparable
single-point data for thermoplastic elastomers. After publication of this part of
ISO 14910 and the analogous document for polyurethanes (ISO 16365‑2), it is the intention to develop ISO 10350‑3 for the acquisition and presentation of comparable single-point data for thermoplastic
elastomers, based on this part of ISO 14910 and ISO 16365‑2, as the basis for the development of thermoplastic-elastomer material standards.
