In case of plate deliveries for orders under the technical supervision of the Russian Maritime
Registry of Shipping (hereinafter Registry), the Registry’s supervision is to be performed in
accordance with the applicable Registry’s Regulations.
The rolled stock delivery under the Registry’s supervision shall be carried out after

The production inspection must be made under a separate program agreed with the Registry in
accordance with the procedure established by the Registry’s Regulations.
3.3 Each plate shall be subject of:
- visual and ultrasonic inspection as per GOST 22727;

3.4 For the mechanical and elongation inspection two plates out of a lot must normally be
selected.
3.5 In case of failure to pass the test re-testing shall be made using a double number of
specimens, cut out of the inspected plate and related to the parameter in question, while the
specimens for retesting may be subjected to a metallographic examination to determine possible
causes of the failure. If any machining defects found on a specimen, such a specimen must be
discarded and replaced with another one. In case of a satisfactory test result using an additional
specimen set, such a plate may be accepted. The lot may be also accepted for delivery in case of
positive results for all other plates of the lot selected for tests. In case of unsatisfactory results of
retesting for at least one plate the plate shall be rejected. In case of two unsatisfactory test results
for plates selected for tests each plate of the lot should be tested.
4 Test methods 4.1 The mechanical inspection should be made using specimens cut at a distance of at least
40 mm off the front/end edge edgeways for at least 20 % of the original plates of each lot.
Form each plate selected for tests three specimens for tension and pull tests to be performed
as per set forth in Appendix B methods shall be sampled.

proportional flat specimens of type 1 with an initial gauge length lo= 5,65⋅ at the steel layer
side.
4.4 The surface check shall be made by a visual inspection without application any optical
devices. If on one or two plate surfaces are oxidation traces due to interaction with the explosive
mixture, such place shall be subject to sandblasting for a complete surface cleaning. The surface
imperfection depth should be determined after a control grinding. The AMg6UM layer thickness
check shall be made using the manufacturer’s method.
4.5 The geometry control shall be made with a calliper as per GOST 166 and a steel measure
tape with a division value of 1mm as per GOST 7502. The strip thickness should be measured
with a microcaliper as per GOST 6507.
4.6 The flatness deviation shall be governed by GOST 26877.
4.7 To determine the intercrystalline corrosion resistance the data of the corrosion resistant
rolled stock manufacturer’s shall be used. If the intercrystalline corrosion resistance data are
unavailable, the steel layer shall be tested as per GOST 6032 using AMU method on two
specimens, cut out along the rolling direction. The test data shall be an input or steel plates.
Plates, which failed to pass the intercrystalline corrosion resistance test at the manufacturer or by
acceptance test, shall not be used for the bimetallic plate production.
4.8 The rest of requirements with regard to acceptance regulations and test methods shall be
as per GOST 21631.
