Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009. This standard replaces GB/T 23848-2009 "Ferrous sulphate for electroplating", and GB/T 23848-2009 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 indicator values for copper, lead, manganese, sulphate and densities in the requirements and delete the requirements for nitrates (see Chapter 3,.2009 Version of Chapter 3); --- Increasing the copper, lead, zinc, manganese and chromium content of the formula (see 4.6.5,4.7.5,4.8.5,4.9.5 and 4.10.5,.2009 edition 4.3, 4.4, 4.5, 4.6 and 4.7); --- Modify the HSR, sulfate and chloride analysis procedures (see 4.5, 4.11 and 4.12,.2009 edition 4.2, 4.8 and 4.10); --- Removed the test method of nitrate content (see.2009 version 4.9); --- Modify the method of determination of density (see 4.13,.2009 edition of 4.11); --- Modify the content of the inspection rules (see 5.1, 5.2, 5.5 and 5.6,.2009 editions 5.1, 5.2, 5.5, 5.6 and 5.7); --- Added "safety" section (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. Jiangxi Nuclear Industry Xingzhong New Materials Co., Ltd., Shandong Institute of product quality inspection, Shandong Beijing Bo Controlling Unit Co., Ltd., South Institute Group. The main drafters of this standard. Du Xingsheng, Zeng Kun, Zou Huiling, Wang Honghai, Liu Nian, Zhou Jian, Xie Dongxiang, Zhang Zhitao, Lu Peng, Qiu Ailing. This standard replaces the standards previously issued as follows. --- GB/T 23848-2009. Plating with ferrous sulfamate Caution --- part of the reagents used in this standard is toxic or corrosive, part of the operation is dangerous. This standard did not indicate Possible security issues. It is the user's responsibility to take appropriate safety and health measures and to ensure compliance with the requirements of the relevant state laws and regulations.

1 Scope

This standard specifies the technical requirements for ferrous sulphamate plating, test methods, inspection rules, signs, packaging, transportation, storage and Safety. This standard applies to metal iron and sulfamic acid as raw materials for the electroplating with sulfamic acid iron.
