scope:

This CP gives a description of the procedures and requirements related to documentation, design and type testing applicable for TA of fibre reinforced thermosetting plastic piping systems.

This CP does not set the design requirements for the fibre reinforced thermosetting plastic piping systems. TA is based on compliance with design requirements given in the rules and/or other regulations and standards referred in Sec.2 [1]. The CP describes how to document compliance with the requirements in order to obtain a TA certificate for the equipment. This includes, where relevant, technical requirements for how the type tests shall be performed.

The Society's type approval certificate will cover one grade of the actual product with the possibility to include variants.

Fibre reinforced thermosetting plastic piping systems with different resin systems are considered as different grades.

Different:

nominal pressures (both internal and external),

joining methods,

diameters,

fire endurance level,

flame spread performance,

conductive or non-conductive performance, as well as a

defined range of fittings (including flanges)

are considered variants of the same grade.

The Society's type approval certificate is normally limited to one manufacturer at one production site, however, other arrangements may be agreed with the Society.

Type tests as specified in Sec.2 [3], shall be carried out and verified in one of the following ways:

at a DNV GL laboratory

at an accredited and recognized testing laboratory or a laboratory accepted by the Society

at the manufacturer's premises in the presence of a surveyor.

The type test results shall be submitted to the Society in form of a test report according to ISO 17025 and the additional requirements for the relevant test standard for evaluation.
