QB/T1655—1992
5.1.2 Method and steps
Wipe the unwritten water-based ballpoint pen tip clean, and then place it on the workbench of the projector so that the pen tip image is displayed on the projection screen. Adjust the focal length to make the projection image clear. Move and rotate the workbench so that the horizontal and vertical coordinate axes on the projection screen are tangent to the ball through the ball seat edge, and read the angle values β, β2 indicated by the instrument when they are tangent, and then calculate the initial writing angle α according to formula (1) or formula (2). When α is 45°, use formula (1); when α is less than 45°, use formula (2). a=45°+ IB=Bal
α=45°

The inspection of water-based water-measuring pens is divided into type inspection and factory batch inspection. 6.7 Type inspection
6.1.1 Type inspection must be carried out when the following situations occur. a. In normal production, there should be regular inspections at least twice a year; b. When designing new products, improving old product designs and production technical conditions have major changes; c. When production is resumed after suspension of 3 months or more; c. When the national quality supervision agency proposes the requirement for type inspection, 6.1.2 During type inspection, more than 40 products should be randomly selected from the products as samples, of which 10 products should be used as inspection samples, and all items listed in Chapter 4 should be inspected item by item. The inspection pass rate is calculated on a single item basis. Among the 5 appearance requirements, except for "complete parts" which is calculated on a single item basis, the pass rate of the other 4 items is calculated comprehensively (see Appendix A for details). Among the inspection items, the pass rate of initial writing performance, line length, pen tip sliding force, pen tip strength and complete parts is 100%, and the pass rate of other items is 90%. 6.2 Factory batch inspection

(AQL) value
Determination of batch quality is expressed according to the number of unqualified products per hundred units of products for each item in accordance with GB/T2828. Only when the products reach the qualified quality level specified in both A and B categories can the inspection batch be judged as qualified. 6.2.4 Disposal after inspection
a. Class A unqualified products shall not be shipped out of the factory. The production department may sort out the products and submit them for inspection again. They may be shipped out of the factory only after passing the inspection. However, the initial inspection of the batch is still considered unqualified; b. Class B unqualified batches can be reworked or downgraded by the production department. When downgrading, the products should have obvious downgraded Chinese symbols such as "substandard" or "substandard products". 7 Marking, packaging, transportation, storage
