Plastics -- Polybutene-1 (PB-1) moulding and extrusion materials -- Part 2: Preparation of test specimens and determination of properties
Это стандарт пересмотрен ISO 21302-2:2019
ISO 8986-2:2009 specifies the methods of preparation of test specimens and the test methods to be used in determining the properties of polybutene‑1 (PB‑1) 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 specified.
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. Properties and test methods which are suitable and necessary to characterize PB 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 8986, as is the designatory property specified in Part 1.
