Foreword

This standard is identical with ISO 718:1990 "Laboratory glassware thermal shock and thermal shock strength test method", is only for a small amount of editing Modifications, with the same technical content.

This standard replaces GB/T 6579-1986 "laboratory glassware thermal shock test method." This standard and GB/T 6579-1986 compared to the main changes are as follows.

--- The name was changed to the standard "laboratory glassware thermal shock and thermal shock strength test method";

--- Deleting the contents of the original standard Method A;

--- Original standard content Method B and Method C combined;

--- Increasing the terms and definitions, impact strength test procedures, and test results are shown representation reported. The standard proposed by China National Light Industry Council.
