DESCRIPTION

BS 6075-9:1981


This standard BS 6075-9:1981 Methods of sampling and test for sodium hydroxide for industrial use is classified in these ICS categories:
  • 71.060.40 Bases

This International Standard specifies a flame atomic absorption method for the determination of the calcium and magnesium contents of sodium hydroxide for industrial use.

The method is applicable to products having Ca and Mg contents greater than

  • 2,5 mg/kg and 0,5 mg/kg respectively, if an acetylene-air flame is used;
  • 0,6 mg/kg and 1,0 mg/kg respectively, if an acetylene-dinitrogen monoxide flame is used.
