Category I:

—	equipment related to safety for which a DNV certificate is required.

Category I equipment is subdivided into IA and IB categorisation.

Category II:

—	equipment related to safety for which a works certificate prepared by the manufacturer is accepted.

Ch.3 Sec.2 A
103   For equipment category I, the following approval procedure shall be followed:

—	design approval, followed by a design verification report (DVR) or type approval certificate
—	fabrication survey followed by issuance of a product certificate.

Ch.3 Sec.2 A
104   Depending on the required extent of survey, category I equipment is subdivided into IA and IB with the specified requirements as given below:

Category IA:

—	pre-production meeting, as applicable, prior to the start of fabrication
—	class survey during fabrication
—	witness final functional, pressure and load tests, as applicable
—	review fabrication record.

Category IB:

—	pre-production meeting (optional)
—	witness final functional, pressure and load tests, as applicable
—	review fabrication record.

The extent of required survey by DNV is to be decided on the basis of manufacturer's QA/QC system, manufacturing survey arrangement (MSA) with DNV and type of fabrication methods.

Guidance note:
It should be noted that the scopes defined for category IA and IB are typical and adjustments may be required based on considerations such as:

-	standard type approved products / MSA agreement
-	complexity and size of a delivery
-	previous experience with equipment type
-	maturity and effectiveness of manufacturer's quality assurance system
-	degree of subcontracting.
