6 Test methods
6.1 The measurement of deformation shall be carried out in accordance with GB/T3300. QB/T1464 1992
6.2 The measurement of caliber error, height error and defect size shall be carried out in accordance with GB/T3301. 6.3 The measurement of water absorption shall be carried out in accordance with GB/T3299, and the sample may be a fragment of the same type of product. 6.4 Determination of thickness: Use an ultrasonic thickness gauge to measure the area above and below the center line of the product height. 7 Inspection rules
Production inspection is divided into factory inspection and type inspection, and the number of unqualified products per 100 units of products (piece counting method) is used for inspection. Products must be inspected and qualified by the inspection department of the manufacturer before they can be shipped, and documents proving the quality of the products must be attached when they are shipped. 7.1 Factory inspection
7.1.1 The factory inspection items are the contents specified in Articles 5.3, 5.5, 5.6 and 5.7 of this standard. 7.1.2 Factory inspection shall be carried out in accordance with the provisions of GB/T2828. The classification of unqualified items, qualified quality level, inspection level and sampling method of each inspection item are shown in Table 4.

7.1.4 The sampling of samples is carried out randomly. The sample quantity of a single product shall be drawn according to the provisions of Table 4: the number of boxes (including sets or stalls) of products shall be drawn according to the special inspection level S-2 of GB/T2828, and then the sample quantity of the batch of products shall be drawn from the number of boxes drawn according to the provisions of Table 4 of this standard.
When it is determined to be an unqualified batch after inspection, the batch of products shall be reworked and reclassified by the delivery party before it can be submitted for inspection again. 7.2 Type inspection
Type inspection shall be carried out once a year. Type inspection shall also be carried out in the following circumstances. 7.2.1
Changes in product raw material formula;
Changes in production process method:
Suspension of production for more than six months and then resumption of production;
An unexpected accident occurs during the production process: The factory inspection results are significantly different from the type inspection results; The national quality supervision agency puts forward the requirements for type inspection. 7.2.2 Type inspection items are all the contents of Articles 5.1 to 5.7 of this standard. 7.2.3
The samples for type inspection shall be drawn from the products within the grade after being fully inspected and graded by the manufacturing inspection department during the current cycle. Type inspection shall be carried out in accordance with the provisions of GB/T2829. The classification of unqualified items, unqualified quality level, discrimination level and 7.2.4
