Each oil purifier must be inspected by the quality inspection department of the manufacturer and be accompanied by a product quality certificate Only after receiving the inspection certificate can it leave the factory. 7.2 Inspection Categories
The product inspection of oil purifiers is divided into two categories: factory inspection and type inspection. Batch products should undergo factory inspection one by one. Type inspection should be carried out when one of the following situations occurs:
a) Trial type identification of new products or old products transferred to factory for production; b) After formal production, if there are major changes in structure, materials, and processes, it may affect Product performance: c) During formal production, a periodic inspection should be carried out regularly or after accumulating a certain amount of production; d) When the product resumes production after a long-term suspension; e) When the factory inspection results are significantly different from the last type inspection: f ) When the national quality supervision agency proposes type inspection requirements. During the type inspection of the oil purifier, sampling and grade assessment should be carried out in accordance with the provisions of relevant standards 7.3
