AbolishedTest methods for aluminium and aluminium alloy foils - Part 1: Determination of thickness by gravimetric method
铝箔试验方法 第1部分：厚度的测定 重量法
Application Summary AI generated
This standard specifies a gravimetric method for determining the thickness of aluminium and aluminium alloy foils by weighing a sample of known area and calculating thickness from its density. It is primarily applied in the quality control and inspection of aluminium foil products used in packaging, electronics, and thermal insulation industries. The method is suitable for verifying foil thickness in manufacturing and testing contexts where direct mechanical measurement is impractical.
