International Standards
ASTM Standards:
Copper Strip: Thickness tolerance refers to ASTM B152, for example, when the thickness is ≤0.1 mm, the tolerance is ±0.012 mm.
EN Standards:
Copper Plate/Copper Strip follows EN 1652 (corresponding to DIN 1787), with thickness ranging from 0.006 mm to 50 mm, and width graded by thickness (e.g. 0.5-0.8 mm width ≤600 mm).
GB/T Standards:
Copper Strip implements GB/T 2059, with a thickness range of 0.5-0.8 mm, a width tolerance of ±0.1 mm, and a condition of O60 (soft state).
