DNV DNVGL-CP-0098 PDF

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

This CP does not set the design requirements to the plywood. 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 material. This includes, where relevant, technical requirements for how the type tests shall be performed.

The Society's type approval certificate will cover one quality grade of the actual product with the possibility to include variants. For plywood this means:

— Grade: one type of wood, from a defined geographical area

— variants: different numbers of plies, i.e. construction, are considered as variants .

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 accepted by DNV GL

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