scope:

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

This CP does not set the design requirements to the adhesive systems. TA is based on compliance with design requirements given in the DNV GL rules and/or other regulations 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 scope of this class programme for adhesives is limited to pre-selecting adhesives by:

carrying out basic performance testing and

defining mechanical performance data for basic joint design.

One type approval certificate will cover one grade of the actual product with the possibility to include colour variants.

Adhesives with different chemical composition are considered different grades. Minor changes, as colour changes, may be accepted provided that it can be proven no differences in mechanical and adhesive behaviour.

Approval covering different adherends is considered variants. The mechanical and adhesive properties shall be proven for all adherends. Different aluminium series like 5000, 6000, etc. are considered variants.

One 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 a recognized and independent laboratory or a laboratory accepted by the Society

at the manufacturer's premises in the presence of a surveyor, after consultation with the the Society's responsible approval centre. It is recommended to test at external testing laboratories due to the long duration of some tests.

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