Foreword

This standard was drafted in accordance with GB/T 1.1-2009 given rules. This standard replaces GB/T 7988-2002 "Determination enamels Corrosion resistant sodium hydroxide solution." And GB/T 7988- Compared to 2002, the main technical changes are as follows. --- Increased determination enamels resistant to other alkaline solution corrosion; --- Material for holding the test solution cylindrical vessel modify S31668; --- Increasing the specimen calculation basis of the total weight loss and corrosion rate. The reference to the standard ISO 28706-4.2008 "Determination of resistance to chemical attack enamel lining of Part 4 of the cylindrical container Alkali Erosion Measurement "solution. The standard proposed by China Petroleum and Chemical Industry Association. The standard glass-lined equipment by the National Standardization Technical Committee (SAC/TC72) centralized. This standard was drafted. Changshu Huamao Chemical Equipment Co., Ltd., Ningbo Mingxin Chemical Machinery Co., Ltd., Jiangyin Silicon Cape enamel Ltd., the chemical industry of non-metallic materials and equipment for Quality Supervision and Inspection Center.
