Annotation

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

This CP does not set the design requirements to the sandwich core materials. TA is based on compliance with design requirements given in the DNV GL 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 Society's type approval certificate will cover one grade of the actual product with the possibility to include variants.

Grade: Sandwich core materials with different chemical composition.

Variants: Different densities with the same chemical composition.

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

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