Furthermore, for the approval scope the following limitations apply:

approval for chain does not cover accessories or vice versa

approval for stud link chain does not cover studless chain or vice versa

approval for a higher grade, e.g. VL K3, may cover a lower grade, e.g. VL K2, provided that the same material specification and manufacturing processes and delivery conditions are used in production as were used for the approval testing. Grade(s) approved on this basis will be included in the approval certificate.

Manufacturer's own heat treatment facilities shall be evaluated and approved by the Society either under this approval programme, or as an approved "heat-treatment workshop" through the separate approval programme DNVGL CP 0351.
