This CP gives a description of the procedures and requirements related to documentation, design and type testing applicable for TA of sandwich adhesives.

This CP does not set the design requirements for sandwich adhesives. TA is based on compliance with design requirements given in the Society's rules and standards. 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 type approval of sandwich adhesives are separated into two different quality grades:

Grade 1: required quality of sandwich adhesives for hull constructions.

Grade 2: required quality of sandwich adhesives for less critical applications.

A type approval certificate issued by the Society will be valid for one quality grade of the actual product with the possibility to include variants.

For sandwich adhesives this means:

quality grade: one base resin/chemical composition

variants: different additives and fillers, and different densities.

All variants shall fulfil the requirements for the same quality grade.

A type approval certificate issued by the Society is normally limited to one manufacturer at one production site, however, other arrangements may be agreed with the Society.

Type tests 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.
