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

This CP does not set the design requirements for the hardwood for tank supports. TA is based on compliance with design requirements given in the rules and/or other regulations and standards. The CP describes the applicable requirements and 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.

For hardwood this means:

grade: one type of wood, from a defined geographical area. Defined by density, lamination, veneer thickness, type of resin

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 [2.3], shall be carried out and verified in one of the following ways:

at one of the Society's laboratories

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

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