The work of preparing Internationa
19、l Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO,
20、also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1
21、. In particular the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).Attention is drawn to the possibility that some of the e
22、lements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

26、erials Part 2: Preparation of test specimens and determination of properties1 ScopeThis 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. Requirements for handling test material
27、 and for conditioning both the test material before moulding and the specimens before testing are given.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
28、that are suitable and necessary to characterize polyamide 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
29、included in this document, as are the designatory properties viscosity number and tensile modulus of elasticity given in ISO 16396-1.2 Normative referencesThe following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document.

Before processing, the moisture content of the material sample shall not exceed 0,2 % (mass fraction) in the case of PAs having a viscosity number 200 ml/g and not exceed 0,1 % (mass fraction) in the case of PAs having a viscosity 2 ISO 2017 All rights reservedBS EN ISO 16396-2:2017ISO 163

For PA46, PA6T/66, PA6T/XT, PA6T/6I/66, PA6T/6I, PA6I/6T and PA NDT/INDT, the moisture content shall be less than 0,1 % (mass fraction).The moisture content of filled or reinforced materials shall be expressed as a percentage of the total mass of the compound. The moistu
44、re content shall be determined in accordance with ISO 15512 and the viscosity number in accordance with ISO 307.To ensure that the moisture content remains low, it is recommended that the sample material in the feed hopper of the injection-moulding machine be blanketed with a suitable gas (for examp
45、le, dried air, nitrogen or argon).Better results may be obtained using a dehumidifier hopper drier.If test specimens are to be prepared by laser sintering (see 4.3 and Annex A), follow the instructions given in Annex A for treatment of the material before processing.4.2 Injection mouldingFor the acq
46、uisition and presentation of comparable data, injection-moulded specimens are used so that valid comparisons between materials can be made. These data represent the most basic approach to the designation of the properties of materials.Injection-moulded specimens shall be prepared in accordance with
47、ISO 294-1, using the conditions specified in Table 1. Such specimens shall be prepared by injection moulding from dry granules. It is essential that the specimens are always prepared by the same procedure using the same processing conditions. The material shall be kept in sealed, moisture-proof cont
48、ainers until it is required for use.NOTE The ISO 294 series will be revised, defining only the injection-moulding conditions and will refer to ISO 20753 for the dimensions of the specimens. Other International Standards that have hitherto used different designations for the same specimen type will a
49、lso be revised to bring the designations into line with those in ISO 20753. Many test standards, specifying test specimen or referring to other standards as ISO 3167 and the ISO 294 series, will be revised in due time and also refer to ISO 20753.Besides injection moulding, other methods are also used to manufacture PA parts, e.g. extrusion, blow moulding and methods using mouldless technologies. Different methods of manufacture can lead to significantly different pro
