The scope is defined in each section for the various disciplines and may refer to standards that apply to the discipline in general, such as for electrical systems. In these cases this document only contains requirements that are particular to diving systems, whereas the generic requirements are given in the referred rules, standard or code. The combined requirements shall then constitute the scope.

Requirements for the diving support vessels, such as the requirements for floatation and positioning ability, are not given in this standard but provided in DNVGL-RU-SHIP Pt.5 Ch.10.

Where the code requires that a particular fitting, material, appliance, apparatus, item or type of equipment should be fitted or carried in a system, or that any particular provision should be made, or any procedure or arrangement complied with, the administration may allow alternative arrangements in that system, provided that the administration is satisfied that such alternatives are at least as effective as the requirements of the code.

(See IMO code of safety for diving systems Ch.2 design, construction and survey 1.5 equivalents.)

This standard is not applicable to SCUBA diving, submersibles including atmospheric diving suits or submarines.
