ASTM A20/A20M,  Spécification normalisée des exigences générales applicables aux tôles en acier pour équipements sous pression (Revison 2020)

Standard specification for general requirements for steel plates for pressure vessels

Remplace ASTM A20/A20M ( de mai 2019).

This general requirements specification covers a group of common requirements that, unless otherwise specified in the applicable product specification, apply to rolled steel plates for pressure vessels covered by a number of other product specifications issued by ASTM. This general requirements specification also covers a group of supplementary requirements that are applicable to several of these product specifications. Such requirements are provided for use if additional testing or additional restrictions are required by the purchaser, and apply only if specified individually in the purchase order. Appendixes provide information on:

• coil as a source of plates for pressure vessels;

• the variability of tensile properties and of Charpy-V-Notch impact test properties in plates for pressure vessels;

• cold bending of plates, including suggested minimum inside radii for cold bending.

These materials are intended to be suitable for fusion welding. When the steel is to be welded, it is presupposed that a welding procedure suitable for the grade of steel and intended use or service will be utilized. In case of any conflict in requirements, the requirements of the applicable product specification prevail over those of this general requirements specification. Additional requirements that are specified in the purchase order and accepted by the supplier are permitted, provided that such requirements do not negate any of the requirements of this general requirements specification or the applicable product specification. For purposes of determining conformance with this general requirements specification and the applicable product specification, values are to be rounded to the nearest unit in the right-hand place of figures used in expressing the limiting values in accordance with the rounding method of Practice E29.
