JB/T 53022-1999
This standard is a revision of JB/T53022-92 "Sliding Valve Vacuum Pump Product Quality Classification".
Compared with JB/T53022-92, the main technical contents of this standard have been changed as follows: the sampling method has been modified;
the noise index has been modified;
the specific power index has been modified;
-the limit total pressure index has been added;
-the exhaust efficiency index at 2Pa has been added for two-stage pumps. This standard replaces JB/T5302-92 from the date of implementation. This standard is proposed and managed by the National Vacuum Technology Standardization Technical Committee. The drafting unit of this standard is Shenyang Vacuum Technology Research Institute, and the main drafters of this standard are Li Yuying and Ren Lihua. This standard was first issued in 1992.

3 Product Quality Grade
3.1 Products are divided into qualified products, first-class products and superior products according to their quality level and use value. 3.2 Product Assessment Items and Indicators
a) Products of all grades shall meet the requirements of 5.2.2 and 5.2.3 of JB/T1246-1997; b) Products of all grades shall also meet the corresponding indicators specified in Table 1 and Table 2. 4 Inspection Rules and Evaluation Methods
4.1 Sampling Method
4.1.1 Composition of Inspection Lots
Products that have passed the inspection in the production plant and entered the warehouse (or the user's place) constitute the inspection lot. The inspection batch can be the same as or different from the production batch, sales batch, and transportation batch, and can be composed of single pumps of the same or different specifications and models, the same quality grade, and basically the same production conditions and production time, but the batch size of each inspection batch shall not exceed 250 units. When there is no clear provision, the composition of the batch, the batch size, and the method of identifying the batch, etc., shall be determined through negotiation. 4.1.2 Sampling plan
A single sampling plan is adopted, with 2 samples per batch and 0 qualified judgment number. 4.1.3 Sample extraction
Samples should be randomly selected from the inspection batch, and sampling can be carried out after the batch is formed or during the batch formation process. 4.2 Test method
4.2.1 The average trouble-free working time shall be assessed using the test report or user use report (continuous or cumulative operating time) within the past 3 years. 4.2.2 Other items shall be inspected in accordance with the provisions of Chapter 7 of JB/T12461997. 4.3 Assessment method
Approved by the State Machinery Industry Bureau on December 30, 1999, and implemented on June 1, 2000
JB/T53022-1999
To determine the quality grade of a product, it must meet the requirements of all assessment items of the grade, otherwise the grade shall be determined according to the lowest indicator achieved. The quality grade of a batch shall be determined by the lowest grade of the two samples. Table 1
