Values are PS in bar gauge for material group 3E0, thickness band vR ≤ 50 mm, taken from the 3E0 row of each PN table. Decimal commas as printed. The 450 °C row is creep-based in the standard (italic) and is the last rated temperature for this group. A separate row for the 50 < vR ≤ 150 mm band is printed in each table and is slightly lower at some temperatures.

EN 1092-1 uses PN (nominal pressure) ratings in bar: PN6, PN10, PN16, PN25 and PN40. PN16 means 16 bar nominal at ambient temperature for EN material group 1, derating with temperature per the EN 1092-1 tables. EN PN ratings are not equivalent to ASME classes in dimensions, even where the pressure looks similar.
