The designation starts with a letter that shows the part in which the materials belongs to. G = Corrosion, Deterioration, and Degradation of Materials ASTM standards that are more than 1200, have been classified in the sevens parts.Ĭ = Ceramic, Concrete, and Masonry Materials ASTM develops materials standards for a variety of uses in different fields and not just for Boiler and high Pressure Vessels.
So, the name of each material start with SA if it belongs to part A and SB for materials in part B then followed by a number.ĪSTM, on the other hand, is not a code but a standard. Part C - Specifications for Welding Rods, Electrodes, and Filler MetalsĪs you see in ASME Section II, only in two first parts, there are materials. Part B - Nonferrous Material Specifications The 4 parts of ASME BPVC Section II are : In the two first parts, ASME introduces those ASTM materials which can be used in boiler or pressure vessel service. But what are the differences between them?ĪSME B&PVC (Boiler & Pressure Vessel Code) Section II is an American code that consists of 4 parts.
This cooperation is often referred to as “joint action”.
Often the ASTM and ASME material specifications are the same and the materials may reflect this fact with a dual ASTM and ASME specification. ASTM and ASME have cooperated with each other in order to prepare material specifications.
