1 Scope
This document specifies the methods of preparation of test specimens and the test
methods to be used in determining the properties of polyamide moulding and extrusion
materials. It gives the requirements for handling test material and for conditioning
both the test material before moulding and the specimens before testing.
This document specifies procedures and conditions for the preparation of test specimens
and procedures for measuring properties of the materials from which these specimens
are made are given. It lists the properties and test methods that are suitable and
necessary to characterize polyamide moulding and extrusion materials.
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 document, as are the designatory
properties viscosity number and tensile modulus given in ISO 16396‑1.
