SCOPE
This MDS specifies the selected options in the referred standard and modified requirements which shall supersede the corresponding requirements in the referred standard.
QUALIFICATIONS
Base material information, shall be submitted with the bid/ be established prior to delivery.
The documentation of base material shall cover both delivered and PWHT condition and shall include strain ageing tests (ref. option 12), typical tensile test results for plates and weldability tests according to Annex E (option 18) within each of the following thickness ranges that are relevant for the order:
25<t ? 40mm
40<t ? 63mm
63<t ? 100mm
100<t ? 150mm
Other thickness ranges related to same chemistry and manufacturing process may apply. In such cases the thickest material in the range shall be tested. The results from PWHT condition shall also meet the specified requirements.
CTOD testing shall be included for weldability testing for t > 40 mm and shall meet a requirement of min. 0,25 mm in as welded condition, and min 0,20 in PWHT condition unless lower values have been accepted by the purchaser. CTOD testing for thicknesses below 40 mm may be required on the basis of special design criteria.Documentation of base material and weldability tests shall cover both as-delivered and PWHT condition and the material shall comply with the specified requirements in PWHT condition. CTOD testing shall be included and shall meet a requirement of min. 0.25 mm (as-welded)/min. 0.20 mm (PWHT condition), unless a lower value has been accepted by the purchaser.

DELIVERY CONDITION
CHEMICAL COMPOSITION
Option 6 and 9.
TENSILE TESTING
Mechanical properties given in Table 5C shall be modified as follows:
Yield Strength (min.) : 460 MPa (all thicknesses)
Tensile Strength : 550 - 700 MPa (all thicknesses)
IMPACT TESTING
EXTENT OF TESTING
SURFACE CONDITION
NON DESTRUCTIVE TESTING (NDT)
SURFACE PROTECTION
All surfaces shall receive a preliminary protective primer coat. Blast cleaning shall comply with ISO 8501-1 Sa 2? and the surface shall remain at Sa 2? until application of the primer. The primer shall consist of 1 coat zinc ethyl silicate primer with 15 microns. Measured on a plane polished steel or glass test plate the DFT shall be maximum 25 microns.
