EN 1119:2009 (E) 3 Foreword This document (EN 1119:2009) has been prepared by Technical Committee CEN/TC 155 “Plastics piping systems and ducting systems”, the secretariat of which is held by NEN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by September 2009, and conflicting national standards shall be withdrawn at the latest by September 2009. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 1119:1996. The modifications are: changed title and scope to remove “reduced articulation” and clarify intent; changed testing sequence from mandatory to suggested; clarified support conditions and requirements. The material-dependent test parameters and/or performance requirements are incorporated in the referring standard. This standard is one of a series of standards on test methods which support System Standards for plastics piping systems and ducting systems. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and the United Kingdom.

EN 1119:2009 (E) 4 1 Scope This European Standard specifies test methods for flexible non-thrust resistant socket-and-spigot joints with elastomeric sealing elements for buried and above ground glass-reinforced thermosetting plastics (GRP) pipeline applications. It covers methods of test for the leaktightness and resistance to damage of the joint only, when subject to specified combinations of longitudinal extension (draw), angular movement (angular deflection), compression (misalignment) perpendicular to the pipe axis and internal pressure. This European Standard is applicable to joints for either pressure or non-pressure applications. NOTE The joints tested in accordance with this European Standard are subjected to conditions which measure their ability to function and thereby prove the design of the joint, especially for type test purposes. These test procedures are applicable to joints for pipes and fittings of all nominal sizes. The tests are suitable for the evaluation of joints intended for applications in which the liquids are conveyed at temperatures specified in the referring standards. 2 Principle A test piece comprising two pieces of pipe jointed together, by incorporation of a socket or inclusion of a double-socket coupler, is subjected to specified combinations of draw, angular deflection and misalignment. In each specified combination the test piece is subjected to a series of test pressures for specified periods of time, including an internal sub-atmospheric test pressure. In addition, joints for pressure applications are subjected to a specified cyclic pressure test. When under pressure, the joint is monitored for leakage.
Between each test condition (see Table 1 and Table 2) the joint is inspected for signs of damage. NOTE It is assumed that the following test parameters are set by the standard making reference to this European Standard: a)
the nominal size of the components to be connected by the joint (see 4.1); b)
the pressure class of the components (see 4.1); c)
the total effective length, L, of the test piece (see 4.1); d)
the number of test pieces (see 4.2); e)
if applicable, the conditioning to be applied (see Clause 5); f)
the test temperature (see Clause 6); g)
sequence of testing, if appropriate (see 7.1); h)
the joint positions (see Table 1 and Table 2); i)
the draw, angular deflection (see 7.2.3) and the force F (see 7.3.5); j)
the permissible change in negative pressure (see 7.5.4). SIST EN 1119:2009
