ASTM A947M-95(2000)

Standard Specification for Textured Stainless Steel Sheet [Metric]

SCOPE
1.1 This specification covers stainless steel, textured sheets, especially for use in electronic packaging applications, for example, cabinet, rack, enclosure, and shelf constructions for telecommunication, computer, and data-processing equipment.  
1.2 This specification applies to all finished flat-rolled stainless products specified by standards organizations such as International Standards Organization (ISO), American Society for Testing and Materials (ASTM), European Committee for Standardization (CEN), German Institute for Standardization (DIN), and others participating in a global standards harmonization effort.  
1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
