5.1 the method of chemical analysis was carried out according to GB 5069.

5.2 the particle size determination was checked by international standard sieves, that is, 120 mesh and 100 mesh were inspected with the international standard sieve 0.125mm and 0.15mm respectively.

Inspection rule editing

6.1 the weight of each batch is not more than 120 t per batch.

6.2 the sample size should be sampled before the batch. The samples for chemical analysis should be sampled after the batch. 25kg take one sample per 20 bags, and each big bag (1000kg) takes one sample.

After mixing the obtained granularity samples, the particle size was determined by 10~20g. After mixing, the samples were reduced to 200g and sent to laboratory for analysis.

6.3 if a chemical component is not qualified or abnormal, a double number of samples in the same batch of products are rechecked once, and the result of the reinspection is the final test result of the product.
