Foreword
This standard was drafted in accordance with the rules given in GB/T 1.1-2009.
This standard replaces GB/T 23846-2009 "cobalt sulphamate for electroplating", compared with GB/T 23846-2009 main technical changes
as follows.
--- Removed the expression of molecular formula and relative molecular mass in range (see Chapter 1, Chapter 1 of.2009 edition);
--- Modify the requirements of sodium, sulphate and density index value, remove the nitrate requirements (see Chapter 3,.2009 edition of the
3 chapters);
--- Increasing the test solution preparation (see 4.2);
--- Increased nickel, copper, iron, lead, zinc, manganese, sodium and chromium content of the formula (see 4.5,4.6,4.7,4.8,4.9,4.10,4.11 and
4.2, 4.3, 4.4, 4.5, 4.6, 4.7, 4.8 and 4.9 for the.2009 edition;
--- Modify the sulfate, chloride and density analysis steps (see 4.13, 4.14 and 4.16,.2009 edition 4.10, 4.12 and
4.14);
--- Modify the determination of pH requirements (see 4.15,.2009 edition of 4.13);
--- Deleted nitrate content test method (see.2009 version 4.11);
--- Modify the content of the inspection rules (see 5.5,.2009 version 5.5, 5.6 and 5.7);
--- Added "safe" chapter (see Chapter 7).
