DNV DNVGL-CP-0109 PDF

This CP gives a description of the procedures and requirements related to documentation, design and type testing applicable for TA of shop primers for corrosion protection of steel plates and sections.

This CP does not set the design requirements to the shop primers for corrosion protection of steel plates and sections. TA is based on compliance with design requirements given in the 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.

A type approval certificate will cover one grade of the actual product with the possibility to include variants. For shop primers this means:

grade: the basis of a shop primer, e.g. zinc epoxy, zinc silicate, iron oxide and percentage (%) level of zinc

variants: colours, pigments and additives.

This type approval concerns only the verification that the shop primer has no detrimental effect on the finished weld.

A type approval certificate is normally limited to one manufacturer at one production site.

Type tests as specified in Sec.2 [3], are to be carried out and verified in one of the following ways:

at a Society's 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.
