Plastics - Sulfone polymer moulding and extrusion materials - Part 2: Preparation of test specimens and determination of properties
|Publication Date:||1 January 2017|
|ICS Code (Thermoplastic materials):||83.080.20|
This part of ISO 25137 specifies the methods of preparation of test specimens and the test methods to be used in determining the properties of sulfone polymer moulding and extrusion materials. Requirements for handling test material and for conditioning both the test material before m oulding and the specimens before testing are given here.
Procedures a nd conditions for the preparation of t est specimens a nd procedures f or measuring properties o f the m aterials f rom which these specimens a re m ade are given. Properties a nd test m ethods which are suitable and necessary to characterize sulfone polymer 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 25137, as are the designatory properties specified in Part 1.
In order to obtain r eproducible a nd c omparable test results, it is necessary t o use the methods o f specimen preparation and conditioning, the specimen dimensions a nd the test p rocedures s pecified herein. Values determined will not necessarily be identical to those obtained using specimens of different dimensions or prepared using different procedures.
