ASTM A 240 method covers the chemical composition, mechanical properties, and specification for materials such as ferritic, austenitic, martensitic, Duplex, Super duplex and high moly stainless steel alloys.
Scope:
This specification covers chromium, chromium-nickel, and chromium-manganese-nickel stainless steel plate, sheet, and strip for pressure vessels and general applications.
Test procedure:
ASTM A240 is used to determine the standard specification for chemical composition and mechanical properties for the material. For Chemical composition, the Composition of carbon, manganese, phosphorous, sulfur, chromium, nickel, molybdenum, copper and other elements are determined. For the mechanical properties, tensile strength, yield strength, elongation hardness, and cold bend is determined. Yield strength is determined by the offset method at 0.2 %. an alternative method of determining yield strength may be based on the total extension under the load of 0.5 %.
Test Specimen:
The orientation of the specimens shall be longitudinal (long axis of the specimen parallel to the final rolling direction, the root of the notch perpendicular to the rolling face).
Data:
Table no: 1 Chemical Composition Requirements, %A
Table 2: Mechanical test Requirement
Conclusion:
Hence, we can say that ASTM A240 gives detailed and thorough information regarding the chemical as well as mechanical test requirements for various types of steel.

The ASTM D2674 is a standard test method for the analysis of sulfochromate etches solution used in the surface preparation of aluminum. The ASTM D2674 standard specifies a method for determining the efficacy of an etchant used to prepare the surface of aluminum alloys for subsequent adhesive bonding.
An immunological method for quantization of Hevea Natural Rubber (HNRL) proteins using rabbit anti-HNRL serum. Rabbits immunized with HNRL proteins react to the majority of the proteins present, and their sera have the capability to detect most if not all the proteins in HNRL.
