1.3 Requirements of identification of product type with certificate

The product is to be provided with visible marking, giving at least the following information:

manufacturer's name or trade mark type designation under which the product is type approved voltage

number of conductors and cross-section.

The marking is to be carried out in such a way that it is visible, legible and indelible throughout the

anticipated life of the product, and that the marks can be traced back to the Type approval certificate.

1.4

Test requirements

The testing is divided into:

visual inspection

electrical/mechanical tests

environmental tests.

4/6

1.4.1 Visual inspection

By visual inspection, it is to be verified that the test sample (e.g. prototype) is in conformity with the

approved plans.

1.4.2 Electrical/mechanical tests

The tests are to be according to the relevant parts of the following Sec.2, table of type tests.

1.4.3 Environmental tests

Tests related to endurance and reliability of the product on board ships, e.g. vibration test, should takeaccount of the environmental strains on board vessels.

1.4.4 How to pick out test samples

The DNV surveyor at DNV Hvik shall normally pick out 4 samples of each cable type to be coveredby the type approval according to the list in Sec.2 of the application form (the smallest and the largest,

and 2 sizes in between).

Cable types of almost equal construction (e.g. same insulation material and same sheath materials but

different braiding materials, or without braiding or without outer sheath) may be specially consideredwith regard to total number of sizes to be picked out for tests.

1.4.5 Production Sample Test (PST)

The production sample test is performed as random tests at suitable intervals in order to ensure that

products from subsequent production conform to result of type tests, ensuring "equal production".These tests are normally carried out by the manufacturer unless stated on the Type Approval certificate.

1.4.6 Routine Tests (RT)

The routine tests constitute the final production control and the manufacturers standard RT are to be

described in the submitted documentation. This tests is normally carried out by the manufacturer unlessstated on the Type Approval certificate.
