7 Inspection rules
7.1 Inspection classification
Product quality inspection is divided into factory inspection and type inspection. 7.1.1 Production inspection
The thread should be inspected and certified by the manufacturer before it can be shipped out of the factory:
) and the product quality standard is attached.
7.1.2 Type control inspectionWww.bzxZ.net
The full test items specified in the technical standard shall be carried out on a daily basis. When one of the following is required, a formal inspection shall be carried out for new products or products transferred from the factory:
) When the raw materials and process have changed,
) In normal production, the annual inspection shall be no less than 1 time;
) After the product is produced for a long time, the net production year shall be compared with the factory inspection. When the difference between the last type inspection and the quality inspection requirements are large, the core organization shall send a formal inspection. 7.2 Typical
7.2.1 The inspection room shall be based on the actual production points, and the two ends shall be taken for about 1.1 years for picking, and the total loss surface quality shall be up to 6 (1.1) two-dimensional belt code wire inspection. 2.2 Type price inspection shall be based on the first car production two-dimensional neutral non-product quality rate (two wires of the disk, take at least 3 meters at the head to 5 meters at the end of the production, and 1 meter reverse inspection. Among them, the surface quality and size of the disk shall be inspected (net inspection 7.3 judgment period
7.31 factory inspection - there must be - no non-conformity, the product is defined as unqualified product. 7.3.2 to the type effect inspection, as long as there is one item does not contain the qualification, the degree of sampling will be carried out for all the support effects. If one item is unqualified, Then the type of pull test will not be set.
Daily supply method, packaging and marking
.1 Hong degree method
1 The surface of the belt should be eliminated and the taste should be removed. In order to produce the effect of the light steam wire factory, 1.m should be used for even wire. If the light wire Hong needs to be opened in pairs, the wire should be opened in pairs. 1.2 The wire should be made of one wire (porcelain), and the manufacturer should not be pregnant with children's heads. Pay attention to the serious bend and cleanliness. Daily.3 If the wire (reel) is not in the table, the wire diameter r:
