ActiveDetermination of six metal elements (iron, calcium, magnesium, zinc, titanium,copper) in polyolefin pipe system
聚烯烃管道中六种金属元素（铁、钙、镁、锌、钛、铜）的测定
Application Summary AI generated
This standard specifies a method for determining the concentration of iron, calcium, magnesium, zinc, titanium, and copper in polyolefin pipe materials. It is applied in quality control and material certification for manufacturers and testing laboratories to ensure that metal content in pipes used for water supply, gas distribution, or industrial fluid transport does not exceed safety or performance thresholds. The standard is particularly relevant for verifying compliance with regulatory limits on metallic impurities that could affect pipe durability, corrosion resistance, or potable water quality.
