DANSK DSF/PREN ISO 24026-2 PDF

1.1 This part of ISO XXXXX specifies the methods of preparation of test specimens and the test methods to be used in determining the properties of Poly(methyl methacrylate)PMMA moulding and extrusion materials. Requirements for handling test material and for conditioning both the test material before moulding and the specimens before testing are given here. 1.2 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 Poly(methyl methacrylate) moulding and extrusion materials are listed. 1.3 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 XXXXX-1. 1.4 In order to obtain reproducible and comparable test results, it is necessary to use the methods of specimen preparation and conditioning, the specimen dimensions and the test procedures specified in this document. Values determined will not necessarily be identical to those obtained using specimens of different dimensions or prepared using different procedures.
