Description

technical field

[0001] The invention relates to an oxidizing solid testing device, in particular to an improved testing device for testing oxidizing solids which can separate the testing system from the measuring system, has high measurement precision, is safe and reliable. Background technique

[0002] An oxidizing substance is a substance that does not necessarily burn itself, but usually may cause or promote the combustion of other oxidizing substances due to the release of oxygen. It belongs to category 5 in the classification of hazardous chemicals. The hazards of oxidizing substances are multifaceted. Therefore, before storage and transportation, oxidizing substances must be identified and further classified to assess their hazards. At present, the latest oxidizing solid test methods and devices used at home and abroad refer to Supplement 2 of the fifth edition of the "Recommendations on the Transport of Dangerous Goods Manual of Tests and Criteria" which is in charge ...
