Key Topics and Requirements
- Scope & product forms
- Round tubes (straight lengths): outside diameters 3 mm to 450 mm; wall thickness 0.3 mm to 10 mm.
- Round tubes (level wound coils): outside diameters 3 mm to 30 mm; wall thickness 0.3 mm to 10 mm.
- Square/rectangular tubes: major outside dimension 5 mm to 150 mm; wall thickness 0.5 mm to 10 mm.
- Material designation
- Material symbols and numbers (e.g., Cu-ETP / CW004A, Cu-OF / CW008A) and defined material condition designations: D (cold worked), H… (hardness-based), R… (tensile-based).
- Mechanical and electrical properties
- Mandatory checks for tensile strength, hardness (Vickers or Brinell), electrical resistivity, and freedom from hydrogen embrittlement.
- Dimensions, tolerances and form
- Requirements for outside dimensions, corner radii, wall thickness, length (manufactured or fixed length), form tolerances, and mass tolerances.
- Sampling & test methods
- Specified sampling procedures and tests: chemical analysis, tensile testing, hardness testing, electrical resistivity, hydrogen embrittlement and bend tests. Rounding and retest rules are included.
- Marking, packaging and conformity documentation
- Declaration of conformity and inspection documentation requirements for supply chain traceability.
