GB/T 6679 General rules for sampling solid chemical products Preparation and storage of specimens 3 3.1 laboratory sample Using GB/T 6679 stipulated in laboratory sample preparation and storage methods. 3.2 original sample For some geometric properties measured for testing certain physical and physico-chemical properties, as well as for determination of hygroscopic moisture. Take about 300g solid Laboratory sample (3.1), which was stored in a sealed container, the container is almost filled sample is appropriate. 3.3 drying specimens Chemical tests for the determination of certain geometrical characteristics and certain physical and chemical physics test. 3.3.1 Sample grinding The sample was milled and sieved until all of 0.125mm sieve pore size of up. The sample mixing sieved at 110 ℃ ± 5 ℃ drying 2h. 3.3.2 Equipment 3.3.2.1 test sieve. its sieve size of 0.125mm. Not tested by introducing an impurity element material, and be based on potassium fluoroborate Properties measured impurity element selected test sieves. 3.3.2.2 mortar. steel made of jade or agate. 3.3.2.3 electric oven. Natural convection ventilation, to control the temperature of 110 ℃ ± 5 ℃. 3.3.3 Procedure 3.3.3.1 About 100g laboratory sample (3.1) through the test sieve (3.3.2.1), the sieve residue particles on the mortar (3.3.2.2 ) Milled and sieved again, sieved material was added to the front of the screen carefully mixing the compound. Repeated grinding, screening, mixing until all samples All through a sieve so far. 3.3.3.2 The sample (3.3.3.1) into a platinum dish, and put into an electric oven (3.3.2.3), and at a temperature of 110 ℃ ± 5 ℃ drying 2h . and After removing the platinum dish from an electric oven, placed in the dryer to cool to room temperature. 3.3.3.3 The sample (3.3.3.2) stored in airtight containers for the storage requirements of the container volume to almost completely filled by the sample Appropriate. ......
