1 Scope This European Standard specifies the functional requirements and test methods for adhesives used for joining the components of unplasticised poly(vinyl chloride) (PVC-U), chlorinated poly(vinyl chloride) (PVC-C), acrylonitrile -butadiene-styrene (ABS) thermoplastic piping systems for fluids under pressure. It provides for the evaluation of conformity of the adhesive for this EN. 2 Normative references The following referenced documents are indispensable for the application of this document.

Unless otherwise specified in this clause, the test pieces shall fulfil the following requirements set in Tables 1 and 2:

The value and tolerances proposed for PVC-C systems are not based on a wide experience. The proposed value, 0,6 mm, seem to be the most adequate at the moment, but it will be followed closely throughout the implementation of this standard. Changes will be introduced, if necessary, in the future revision of this standard.

The value and tolerances proposed for PVC-C systems are not based on a wide experience. The proposed values seem to be the most adequate at the moment, but they will be followed closely throughout the implementation of this standard. Changes will be introduced, if necessary, in the future revision of this standard. b To prevent deformation of the fitting during 60 °C test at PVC-U it is recommended to use a fitting with greater wall thickness (e.g. use PN 16 fitting when tested for 10 PN) or to support the fitting. c PN – Nominal pressure (MPa).
When the adhesive is specified for a piping system with conical fittings, these fittings shall be used for testing the internal pressure resistance. The inside diameter of the sockets shall be in accordance with the relevant standards. 4.4 Shelf life The adhesive, stored in unopened containers in accordance with the manufacturer's instructions for the specified shelf life shall still meet the requirements in Table 3 at a setting time of 1 day and conform to the manufacturers specifications for application properties. 5 Evaluation of conformity 5.1 General The conformity of the adhesives for pressure thermoplastic piping systems to the requirements of this standard and with the stated values shall be demonstrated by: • initial type testing;
• factory production control by the manufacturer, including product assessment; • batch release test.

Initial type testing 5.2.1 General Initial type testing shall be performed at the beginning of the production of a new adhesive for thermoplastic piping systems or at the beginning of a new method of production (where this may affect the stated properties). Historical data may be used insofar as tests previously performed on the same adhesive in accordance with the provisions of this standard (same characteristic(s), test method, sampling procedure, system of attestation of conformity, etc.) may be taken into account. 5.2.2 Characteristics All characteristics in Table 5 shall be subject to initial type testing.

The results of all initial type tests shall be recorded and held by the manufacturer for at least ten years after the product for which the ITT is representative ceases production (see 5.2.1). 5.2.3
Sampling, testing and conformity criteria 5.2.3.1 Sampling Initial type testing shall be performed on samples of adhesives for thermoplastic piping systems representative for the manufactured adhesive type. 5.2.3.2 Conformity criteria For the conformity with the requirements of this standard, all test results shall equal or exceed the values for the test. 5.3 Factory production control (FPC) 5.3.1 General The manufacturer shall establish, document and maintain an FPC system.
