Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009. This standard replaces GB/T 23847-2009 "nickel sulphamate for electroplating", and GB/T 23847-2009 compared to the 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 indicators of cobalt, calcium, magnesium, sulphate and density, remove the nitrate, free ammonia requirements (see Chapter 3, 2009 Edition Chapter 3); --- Increasing the cobalt, copper, iron, lead, zinc, manganese, calcium, magnesium and chromium content of the formula (see 4.5.5,4.6.5,4.7.1.5,4.7.2.5,4.8.1.5, 4.8, 4.5, 4.9.1.5 and 4.9.2.5,.2009, versions 4.2, 4.3, 4.4, 4.5, 4.6, 4.7, 4.8, 4.9 and 4.10); --- Modify the test method of iron content (see 4.5,.2009 edition 4.4); --- Modify the analytical procedures for sulphate and chloride (see 4.10 and 4.11,.2009 edition 4.11 and 4.13); --- Modify the determination of pH requirements (see 4.12,.2009 edition of 4.15); --- Deleted nitrate content and free ammonia content of the test method (see the.2009 edition of 4.12 and 4.14); --- Modify the method of determination of density (see 4.13,.2009 edition of 4.16); --- 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). This standard proposed by the China Petroleum and Chemical Industry Federation. This standard by the National Standardization Technical Committee sulfur and sulfuric acid Technical Committee (SAC/TC63/SC7) centralized. This standard was drafted unit.
