This standard is a revision of JB/T5352394 "Multi-rope friction hoist product quality classification". The product standard based on this standard is GB/T10599-1998 "Multi-rope friction hoist". Compared with JB/T5352394, this standard has basically not changed the main technical content except for the editorial modification of the original standard. However, in order to be more perfect and accurate, the expression of some technical contents has been modified, and some specific contents have been supplemented, mainly: - the product standard based on it has been changed to the new standard GB/T10599-1998 - the specific size, accuracy, and surface roughness of the original standard inspection part in Table 4 have been cancelled and replaced with the functional name of the part; - the accuracy requirements related to the inspection part and the measuring point diameter are supplemented with different inspection requirements corresponding to different diameters of the measuring point. This standard replaces JB/T53523-94 from the date of implementation. This standard is proposed and managed by the National Technical Committee for Standardization of Mining Machinery. The responsible drafting unit of this standard: CITIC Heavy Machinery Company. The main drafters of this standard: Jiang Zhaoqiu, Zhang Yingshuang, Li Gang, Cai Jingying, Tian Min. This standard was first issued in November 1987 as JB/ZQ8116-87, and the standard number was adjusted to JB/T53523-94 in September 1994. 1 Scope

3.1 Grading Principles
The quality grade 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 in the production process and the user's evaluation opinions. It is divided into three grades: qualified products, first-class products and superior products. 3.1.1 Qualified products
Approved by the State Bureau of Machinery Industry on March 30, 2000, implemented on October 1, 2000
JB/T53523—2000
Organize production according to current standards, and the quality level of the actual products meets the requirements of the corresponding standards. 3. 1. 1. 1
The quality of the product production process is stable.
3.1.1.3 The accessories and supporting products can ensure that the main machine reaches the level of qualified products. 3.1.1.4 Users evaluate that the product performance meets the use requirements. 3.1.2
First-class products
3.1.2.1 The quality indicators of the product's structure, performance, accuracy, safety, hygiene, reliability and life span reach the general international level, and the quality level of the actual products reaches the general level of similar international products. 3.1.2.2 The quality of the product production process is stable. 3.1.2.3
Accessories and supporting products can ensure that the main machine reaches the first-class level. Users evaluate that the product has a good use effect and the product is competitive in the domestic market. 3.1.2.4
3.1.3 Superior products
3.1.3.1 The quality indicators of the product such as structure, performance, accuracy, safety, hygiene, reliability and life have reached the international advanced level, and the physical quality level has reached the advanced level in the past five years compared with similar foreign products. 3.1.3.2 The quality of the product production process is stable. 3.1.3.3 Accessories and supporting products can ensure that the main machine reaches the superior level. 3.1.3.4 Users evaluate that the product quality is equivalent to the advanced level of similar international products and the product is competitive in the international market. 3.2 Quality grade indicators
