GB/T 15077-2008 Geometric size measuring methods of precious metals and their alloy materials
Abstract
This method specifies a method for directly measuring the geometric dimensions of precious metals and their alloy sheets, strips, tubes, wires, rods, and composites. This method is suitable for measuring the geometric dimensions of precious metals and their alloy sheets, strips, tubes, wires, rods, and composites. The measurement range is as follows: for soft metals (pure gold and pure silver), the diameter of wires, rods, and strips must be greater than 0.1 mm; for hard metal wires, rods, and strips, the diameter must be greater than 0.03 mm; for soft metal (pure gold and pure silver) strips and sheets, the thickness must be greater than 0.1 mm; for hard metal strips and sheets, the thickness must be greater than 0.05 mm; and for tube diameters, the hole diameter must be greater than 3.0 mm.
