Foreword
This standard was drafted in accordance with the rules given in GB/T 1.1-2009.
This standard replaces GB/T 23851-2009 "road deicing deicing salt," compared with GB/T 23851-2009, in addition to editorial changes
The main technical changes are as follows.
--- Modify the standard name;
--- Modify the scope (see Chapter 1,.2009 edition Chapter 1);
--- Added terms and definitions (see Chapter 3);
--- Increased classification (see Chapter 4);
--- Modify the appearance (see 5.1,.2009 version 3.1);
--- Modify the name of the technical indicators, from the "dissolution rate" to "solid dissolution rate" (see 5.2,.2009 edition 3.2);
--- Modify the name of the technical indicators, from "melting ice snow capacity" to "relative snow melting ice capacity" (see 5.2,.2009 edition 3.2);
--- Modify the "carbon steel corrosion rate" target (see 5.2,.2009 edition 3.2);
--- Removed the "concrete corrosion rate" indicators of the project (see.2009 version 3.2);
--- Modify the "road friction attenuation rate" indicator (see 5.2,.2009 edition 3.2);
--- Modify the mercury, cadmium, chromium, lead, arsenic five indicators of the unit (see 5.2,.2009 edition 3.2);
--- Increased the "relative damage rate of plant seeds" "solid water" "water insoluble" and "chloride" indicator project (see 5.2);
--- Increasing the "deicing salt test solution" concentration requirements (see 6.3);
--- Modify the "Relative deicing ice capability" determination (see 6.5,.2009 edition 4.5);
--- Increasing the "mercury content" determination (see 6.11.2);
--- Increasing the "determination of cadmium content" (see 6.12.2);
--- Increasing the "chromium content" determination (see 6.13.2);
--- Increasing the "lead content" determination (see 6.14.2);
--- Modify the "arsenic content" determination (see 6.15,.2009 edition of 4.15);
--- Modify the "factory inspection project" (see 7.1,.2009 edition 5.1.2);
--- Modify the "batch output" (see 7.2,.2009 version 5.2);
--- Modify the "solid product packaging" (see 9.1,.2009 edition 7.1.1).
