Detailed introduction

Particle size was determined by international standard sieving test. Light burnt magnesia powder (120 mesh and 100 mesh) was tested by international standard sieving test with pore size of 0.125 mm and 0.15 mm, respectively.

Inspection Rules

The weight of each batch of finished products is not more than 120 t.

Samples for particle size determination should be sampled before group batches and samples for chemical analysis should be sampled after group batches. Samples were taken in small bags (25kg) for every 20 bags and in large bags (1000kg).

After fully mixing the obtained particle size samples, the particle size was determined by point sampling of 10-20g. The mixed samples were reduced to 200 g and sent to the laboratory for analysis.

If a chemical composition is unqualified or abnormal, double quantity of samples will be re-examined in the same batch of products, and the re-examination results will be the final inspection results of the batch of products.
