Reading the table: The heading rows give the supply condition (AR/CR, TMCP or N) and each society; each row gives the society’s designation for one grade, for example grade A is “AB/A” for ABS, “BVA” for BV, “NV A” for DNV, “GL-A” for GL, “KRA” for KR, “LRA” for LR, “KA” for NK and “RINA-A” for RINA. State which designation your certificate should carry.
How the Four Ship Building Pages Differ
The four pages cover steel for ship building and oil platforms: classified plate in one page and three rolled section types, bulb flats, flat bars and angles, in the others. The plate page lists the grades by classification society; the section pages give size, weight and tolerance tables.
| Page | What it covers | Product form |
|---|---|---|
| PLATE (this page) | Plate sizes, standards and the classification society grade table | Plate, 3–180 mm thick |
| FLAT BULB | Bulb-flat size table with area, weight and allowable deviation | Section, 80 × 5 up to 430 × 20 |
| FLAT BAR | Flat-bar size table with area, weight and allowable deviation | Section, 8 × 100 up to 30 × 450 |
| ANGLE | Angle size table with section area and weight, and JIS G3192 tolerances | Section, L200 × 90 and larger |
State the grade, classification society and size on your enquiry; section sizes are listed as designations on the pages.
