ISO 12162:2009(E) © ISO 2009 – All rights reserved iii Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards 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 organizations, 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. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 12162 was prepared by Technical Committee ISO/TC 138, Plastics pipes, fittings and valves for the transport of fluids, Subcommittee SC 5, General properties of pipes, fittings and valves of plastic materials and their accessories — Test methods and basic specifications. This second edition cancels and replaces the first edition (ISO 12162:1995), which has been technically revised. SIST EN ISO 12162:2010

ISO 12162:2009(E) iv © ISO 2009 – All rights reserved Introduction The revision of this International Standard incorporates the introduction of a CRSθ,t value (categorized required strength at a temperature θ and time t), in addition to the MRS classification and the introduction of minimum design coefficients for additional materials. The classification in this International Standard does not qualify a material for a specific application. For specific applications, the relevant product standards require that additional mechanical and physical properties be met. SIST EN ISO 12162:2010

INTERNATIONAL STANDARD ISO 12162:2009(E) © ISO 2009 – All rights reserved 1 Thermoplastics materials for pipes and fittings for pressure applications — Classification, designation and design coefficient 1 Scope This International Standard establishes the classification of thermoplastics materials in pipe form and specifies the material designation. It also specifies a method for calculating the design stress. It is applicable to materials intended for pipes and fittings for pressure applications. NOTE 1 Classification, minimum design coefficient and calculation method are based on the resistance to internal pressure with water at 20 °C for 50 years, derived by extrapolation using the method given in ISO 9080. NOTE 2 Design coefficients for multilayer pipes are described in the appropriate product (system) standards. 2 Normative references The following referenced documents are indispensable for the applicati
