Key Differences
≠Temper designation systems are different. IS 407 uses alphabetic codes (O, HH, H), while ASTM uses alphanumeric codes (O60, H02, H04) and EN uses material condition codes based on minimum tensile strength (e.g., R220, R290).
≠Material grade nomenclature varies. IS 407 uses abbreviations like 'ETP' and 'DHP', whereas ASTM uses UNS numbers (e.g., C11000, C12200) and EN uses alphanumeric symbols (e.g., Cu-ETP/CW004A, Cu-DHP/CW024A).
≠Mechanical property specifications for equivalent tempers are not identical. IS 407 often specifies a range for tensile strength and hardness (min-max), while EN and ASTM typically provide a minimum value, allowing for slightly different process controls.
≠IS 407 includes a mandatory bend test for all materials and tempers, whereas in standards like ASTM B152, bend tests are typically supplementary requirements to be agreed upon between purchaser and supplier.
Key Similarities
≈All standards cover the same primary product forms: wrought copper in flat-rolled sheet and strip for general engineering applications.
≈They all specify requirements for common high-purity copper grades, including Electrolytic Tough Pitch (ETP) and Deoxidized High Phosphorus (DHP) copper.
≈The core technical requirements are consistent, with all standards specifying limits for chemical composition, mechanical properties (tensile strength, elongation, hardness), and dimensional tolerances.
≈The fundamental test methods referenced for determining properties (e.g., tensile testing, chemical analysis) are based on globally recognized principles.
