Foreword

This standard was drafted in accordance with the rules given in GB 1.1-2009. This standard replaces GB/T 15893.1-1995 "Industrial circulating cooling water turbidity measuring scattered light method" and GB/T 15893.1- Compared to 1995, the main technical changes are as follows. --- Turbidity units FNU replaced by the NTU; --- Increased formazin turbidity standard solution preparation list (see 4.3); --- Modify the scattered light turbidity meter light source incident light angle and measure the receiver (see 5.1, version 5.1 in 1995). The standard reference method using redrafted ISO 7027.1999 "Determination of water turbidity of the" establishment, and ISO 7027.1999's Non-equivalent. The standard proposed by China Petroleum and Chemical Industry Association. This standard by the National Standardization Technical Committee chemical water treatment chemicals Technical Committee (SAC/TC63/SC5) centralized. This standard is drafted by.
