Foreword
This standard is drafted in accordance with the rules given in GB/T 1.1-2009.
This standard replaces YS/T 642-2007 "platinum/niobium anode composite wire for cathodic protection". This standard compared with YS/T 642-2007, the main
Have the following changes.
--- increase the product specifications φ4mm ~ φ10mm and allow deviation requirements;
--- modify the chemical composition of raw materials requirements;
--- increase the product combination strength detection method.
This standard is proposed by the National Committee for Standardization of Nonferrous Metals (SAC/TC243).
