18、andards bodies (ISO member bodies). The work of preparing International 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 o
19、rganizations, governmental and non-governmental, in liaison with ISO, 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 i
20、ts further maintenance are described in the ISO/IEC Directives, Part 1. 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/d
21、irectives).Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights.

The reason for modi
25、fication is for applicability to other plastics materials, other sizes and/or other test conditions and alignment with texts of other standards on test methods. This edition of ISO 3501 is prepared under the Vienna Agreement, so that the content is also aligned with EN 712:1994, which will be replac

The use of this International Standard can involve hazar
28、dous materials, operations, and equipment. This International Standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this International Standard to establish appropriate safety and health practices and determine the a
29、pplicability of regulatory limitations prior to use.1 ScopeThis International Standard specifies a method for checking the ability of assembled uniaxial joints between fittings and plastic pressure pipes to withstand longitudinal tensile stresses. The test applies regardless of the design and materi
30、al of the fitting used for jointing plastics pipe.This test method is not applicable to fusion-welded joints.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
