This standard is a revision of QB1659-92 "Toothbrush". The main revisions are: the bristles of all toothbrushes must be rounded, and the products sold must be packaged. In addition, it is added that disposable toothbrushes are also applicable to this standard, which can effectively protect the interests of consumers and fight against counterfeiting and inferior products.
This standard also quotes part of GB9689-88 "Food Hygiene Standard". This standard is proposed by the Quality Standards Department of the China Light Industry General Association. This standard is under the jurisdiction of the National Daily Miscellaneous Products Standardization Center. The drafting units of this standard are: Shanghai Kitchen Factory, Suzhou No. 9 Plastic Factory, Procter & Gamble (China) Co., Ltd., and Beijing No. 2 Light Industry Center Measurement Station.
The main drafters of this standard are: Gong Ting, Zhu Bairong, Gao Jie, Huang Liang, and Zhang Xiaojing. From the implementation of this standard, the former Light Industry Ministry Standard QB165992 "Toothbrush" will be invalid. Scope

5.5.1 Inspection of grinding single filament top wheel hemp
(1)
5.5.1.1 For flat-bristle toothbrushes, take three points on the bristle surface at random, then remove the three points of the hair bundle, stick them on the paper surface, observe them under a microscope of 30 times or more, and calculate the qualified rate. 5.5.1.2 For special-shaped bristle toothbrushes, take one point each on the high, middle and low sides of the bristles, remove the three points of the hair bundle, stick them on the paper surface, observe them under a microscope of 30 times or more, and calculate the qualified rate. Grinding qualified rate (%) = n/mx100
Where: n-
- number of qualified top wheel contours of single filaments
- total number of single filament samples.

6.2.3 If the acceptance inspection determines that a batch is unqualified, the batch of products shall be reworked before re-inspection. When the consignee proposes physical and chemical test requirements beyond this standard, the supply and demand parties shall negotiate to resolve the issue. 6.3 Type inspection
6.3.1 For the type inspection, 25 samples shall be randomly selected from the qualified products of the delivery inspection for inspection of all technical requirements.
Type inspection shall be carried out in any of the following cases. a)
Trial production and identification of new products or old products for transfer to factory production: when there are major changes in structure, materials, and processes after normal production, which may affect product performance: during normal production, it shall be carried out once a year, and when production is resumed after the production is stopped for 1 year;
When there is a major difference between the factory inspection results and the last type inspection: when the national quality supervision agency proposes a type inspection requirement. Type inspection shall be carried out in accordance with the provisions of GB2829, using a single sampling plan of discrimination level I. The classification of unqualified products, inspection items, technical requirements, test methods, unqualified quality level (RQL), and discrimination array are shown in Table 5. Table 5
