3 quality level
3. 1 rating principle
The quality level of the product is determined according to the adopted standards, the technical level of the product, the inspection of the finished product, the quality inspection during the production process and the opinions of the user evaluation. It is divided into two grades: the qualified product and the first-class product.
3. 1. 1 qualified product
3. 1. 1. 1 Organize production according to current standards, and the physical quality level meets the requirements of the corresponding standards.
3. 1. 1. 2 The quality of the production process is stable.
3. 1. 1. 3 accessories and supporting products can ensure that the host reaches the level of qualified products.
3. 1. 1. 4 User evaluation Product performance meets the requirements for use.
3. 1. 2 first-class products
3. 1. 2. 1 The quality index of structure, performance, precision, safety, hygiene, reliability and life of the product has reached the international general level, and the physical quality level has reached the general level of international similar products.
3. 1. 2. 2 The quality of the production process is stable.
3. 1. 2. 3 Accessories and supporting products can ensure that the host reaches the first-class level.
3. 1. 2. 4 User evaluation The product has a good effect and the product has competitiveness in the domestic market.
3. 2 Quality Grade Index The quality grade index of the agitation tank should meet the requirements of Table 1 .
3. 3 finished product inspection
The finished product inspection project shall comply with the requirements of Table 2 .
3. 4 quality inspection during production
3. 4. 1 Assembly, painting and packaging quality inspection items shall comply with the requirements of Table 3 .
3. 4. 2 The quality of the main parts processing and manufacturing (key projects and major projects) inspection items shall at least include the contents specified in Table 4 .
3. 5 User evaluation comments should have three user certification materials or performance test reports for product quality evaluation as the basis for assessing the quality level.
4 test methods
4. 1 test conditions
4. 1. 1 The test product shall be a qualified product.
4. 1. 2 test site:
a) The ambient temperature should be in the range of 0~40 °C;
b) The ambient noise value should be lower than the measured sample noise value by 10 dB(A) ;
c) the power supply voltage deviation shall not exceed ± 5% ;
4. 2 test content
4. 2. 1 The finished product, assembly, painting and packaging quality inspection items, methods and required instruments shall comply with the requirements of Table 5 .
4. 2. 2 Major parts processing and manufacturing quality inspection items (key projects and main projects), methods and required instruments shall comply with the requirements of Table 6 .
5 inspection rules
5. 1 sampling method
5. 1. 1 Sample of finished product inspection One piece of product produced in small batches is taken.
5. 1. 2 Samples in the production process The products produced in small batches are taken from one to three or from the whole machine.
5. 2 decision rules
5. 2. 1 All test items are only allowed to be inspected and evaluated in the sample. If any item fails, it is not allowed to double the spot check.
5. 2. 2 During the test, the following items are judged as unqualified items:
a) If the item to be inspected is not tested (the main items between the processes can be checked according to the original inspection record);
b) The physical properties, chemical properties, flaw detection, carburizing layer and other items of the material are not detected on site and there is no original record or test report.
5. 3 assessment results
5. 3. 1 According to the measured results of the product, four indicators should be calculated:
a) the pass rate of the finished product inspection project;
b) the qualification rate of assembly, painting and packaging quality inspection items;
c) the pass rate of key parts of major parts;
d) The main project qualification rate of major parts.
5. 3. 2 Assess the quality level of the entire batch of products according to the lowest level of the measured results.
5. 3. 3 A batch of products of a grade, each of which shall not be rated higher than the grade specified in the batch.
