6.1 Inspection classification
The inspection of civil black powder is divided into type inspection and factory inspection. GB 18450--2001
Type inspection is conducted when production is finalized or when production is resumed after more than one year of suspension, or when there is a major change in product structure. 6.2 Inspection items
Inspection items are appearance and all items in Table 2. 6.3 Batch
Each batch shall consist of products manufactured with basically the same raw materials, processes, equipment conditions, etc. The batch size of granular medicine shall not be less than 400kg and not more than 7000kg; the batch size of powdered medicine shall not be less than 200kg and not more than 3000kg. 6.4 Sampling
6.4.1 Appearance inspection
6.4.1.1 Classification of non-conformities
a) Class B non-conformities: There are visible metal chips, glass, sand particles, and potassium nitrate white frost or yellow sulfur spots on the surface of the medicine particles.
b) Class C nonconformity: There are visible sawdust and fibers, the tumbled medicine pellets are dull and have slight lumps. 6.4.1.2 Sampling plan
The sampling of appearance inspection shall be carried out in accordance with the provisions of GB/T2828, and the required samples shall be randomly selected from the inspection batch submitted. A single sampling plan is adopted, the sample unit is box, the inspection level is the general inspection level I, the AQL value of Class B nonconformity is 1.5, and the AQI value of Class C nonconformity is 6.5.
Note: Appearance inspection is carried out during the packaging inspection process. 6.4.2 Physical and chemical performance test
The samples required for the physical and chemical performance test are randomly selected from the samples that have passed the appearance test. The total amount of samples for each product number of granular medicine should not be less than 3kg, and the total amount of samples for powdered medicine should not be less than 0.5kg; after mixing them evenly, take 100g of each and put them into a clean and dry ground-mouth bottle for analyzing the content and density of potassium nitrate, sulfur, charcoal and moisture; the remaining part of the granular medicine is put into a clean and dry cloth bag for analyzing the particle size. The remaining part of the powdered medicine is put into an unweighed cloth bag. The samples taken should be accompanied by a label indicating the product name, product number, batch number, sampling date and the name of the sampler. 6.5 Judgment rules
If all the items tested meet the requirements, the batch of products is judged to be qualified. If one of the physical and chemical performance indicators is unqualified, re-sampling can be carried out from double the number of packaging boxes, and the unqualified items can be re-tested. If the re-test is qualified, the batch of products is judged to be qualified. Otherwise, the batch of products is judged to be unqualified. 7 Marking
