标准范围
This document specifies the methods of preparation of test specimens and the test methods to be
used in determining the properties of PE-UHMW 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 gives the procedures and conditions for the preparation of test specimens and
procedures for measuring properties of the materials from which these specimens are made. Properties
and test methods which are suitable and necessary to characterize PE-UHMW 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 document, as are the designatory properties specified in ISO 21304-1. This document specifies the
materials with MFR less than 0,1 g/10 min at 190 °C /21,6 kg based on ISO 17855-1.
The methods of preparation and conditioning, the specimen dimensions and the test procedures
specified in this document are used in order to obtain reproducible and comparable test results. Values
determined will not necessarily be identical to those obtained using specimens of different dimensions
or prepared using different procedures.
