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 15877-3 was prepared by the European Committee for Standardization (CEN) Technical Committee CEN/TC 155, Plastics piping systems and ducting systems, in collaboration with ISO Technical Committee ISO/TC 138, Plastics pipes, fittings and valves for the transport of fluids, Subcommittee SC 2, Plastics pipes and fittings for water supplies, in accordance with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement).

This part of ISO 15877 is part of a System Standard for plastics piping systems of a particular material for a specified application. There are a number of such System Standards.

The System Standards are consistent with general standards on functional requirements and recommended practices for installation.

This second edition cancels and replaces the first edition (ISO 15877-3:2003).

ISO 15877 consists of the following parts ¹⁾ , under the general title Plastics piping systems for hot and cold water installations — Chlorinated poly(vinyl chloride) (PVC-C):

• Part 1: General
• Part 2: Pipes
• Part 3: Fittings
• Part 5: Fitness for purpose of the system
• Part 7: Guidance for the assessment of conformity [Technical Specification]

At the date of publication of this part of ISO 15877, System Standards Series for piping systems of other plastics materials used for the same application are the following:

ISO 15874 (all parts), Plastics piping systems for hot and cold water installations — Polypropylene (PP)

ISO 15875 (all parts), Plastics piping systems for hot and cold water installations ― Crosslinked polyethylene (PE-X)

ISO 15876 (all parts), Plastics piping systems for hot and cold water installations ― Polybutylene (PB)

ISO 22391:— ²⁾ (all parts), Plastics piping systems for hot and cold water installations ― Polyethylene of raised temperature resistance (PE-RT)

Introduction

The System Standard, of which this is Part 3, specifies the requirements for a piping system when made from chlorinated poly(vinyl chloride) (PVC-C). The piping system is intended to be used for hot and cold water installations and for heating system installations.

In respect of potential adverse effects on the quality of water intended for human consumption caused by the product covered by this part of ISO 15877, the following are relevant.

• a) This part of ISO 15877 provides no information as to whether the product may be used without restriction in any of the Member States of the EU or EFTA.
• b) It should be noted that, while awaiting the adoption of verifiable European criteria, existing national regulations concerning the use and/or the characteristics of this product remain in force.

Requirements and test methods for materials and components, other than fittings, are specified in ISO 15877-1 and ISO 15877-2. Characteristics for fitness for purpose (mainly for joints) are covered in ISO 15877-5. ISO/TS 15877-7 gives guidance for the assessment of conformity.

This part of ISO 15877 specifies the characteristics of the fittings.

1 Scope

This part of ISO 15877 specifies the characteristics of fittings made from chlorinated poly(vinyl chloride) (PVC-C) for piping systems intended to be used for hot and cold water installations within buildings for the conveyance of water, whether or not intended for human consumption (domestic systems) and for heating systems under design pressures and temperatures according to the class of application (see Table 1 of ISO 15877-1:2009).

This part of ISO 15877 covers a range of service conditions (application classes) and design pressure classes. For values of T_D, T_max and T_mal in excess of those in Table 1 of ISO 15877-1:2009, this part of ISO 15877 does not apply.

It also specifies the parameters for the test methods referred to in this part of ISO 15877.

In conjunction with the other parts of ISO 15877, it is applicable to PVC-C fittings, their joints and joints with components of PVC-C, other plastics and non-plastics materials intended to be used for hot and cold water installations.

This part of ISO 15877 is applicable to fittings of the following types:

• fittings for solvent cement joints;
• mechanical fittings;
• fittings with incorporated inserts.
