This standard is a revision of JB/T56037-92 "Quality Grading of Polyester Film and Polyester Fiber Nonwoven Soft Composite Material Products". Compared with JB/T56037-92, this standard has modified the writing format of the standard. According to the provisions of IEC60626--2:1995, the performance "normal bonding" is changed to "delamination": "hot adhesion" is changed to "heat-affected", and the other technical contents are unchanged
This standard will replace JB/T56037-92 from the date of implementation. This standard was proposed and coordinated by the National Technical Committee for Standardization of Insulating Materials. The drafting unit of this standard: Guilin Electric Science Research Institute. The drafters of this standard: Yang Shouyi, Huang Wei. This standard was first issued on November 10, 1988, revised for the first time on May 21, 1992, and revised for the second time in 1999. This standard is entrusted to the National Technical Committee for Standardization of Insulating Materials for interpretation. I

All standards are subject to revision. Parties using this standard should explore the possibility of using the latest versions of the following standards: GB/T5591.1-1985 Definition and general requirements for electrical insulating soft composite materials (IEC6062G-1:1979) GB/T5591.2-1985 Test piece method for electrical insulating soft composite materials (IEC60626-2:1978) GB/T12707-1991 Guidelines for quality classification of industrial products JB/T4060-1991
3 Classification and naming
Polyester film, polyester fiber, non-woven fabric, soft composite materials (IEC60626-3:1988 No. 500) According to the provisions of JB/4060, the products are divided into two types according to the nominal thickness of polyester fiber woven fabrics. , see Table 1, Table 1
Product plastic
4 Requirements
Nominal thickness of polyester fiber woven fabric
0.07~0.10
4.1 Product quality grading requirements for product performance, the performance requirements of 6630 type shall comply with the provisions of Table 2, and the performance requirements of 6G30A type shall comply with the provisions of Table 3. The performance requirements of qualified products in Table 2 and Table 3 are consistent with the regulations in Chapter 4 of B4060-1991. 4.2 Evaluation of product quality grades
4.2.1 Necessary conditions for superior products
4.2.1.1 After the suppression sample inspection, if one sample of the product meets the performance requirements of the superior product, it will be recorded as 5 points, if it meets the performance requirements of the first-class product, it will be recorded as 4 points, and if it meets the performance requirements of the qualified product, it will be recorded as 3 points. If the sum of the scores of the three samples of the product is less than 9 points are considered to have met the performance requirements of qualified products; 9 points or more and no sample score is less than 3 points are considered to have met the performance requirements of qualified products; 12 points or more are considered to have met the performance requirements of first-class products; 14 points or more are considered to have met the performance requirements of superior products. 4.2, 1.2 The results of the type inspection in four quarters within two years shall be that the product has met the performance requirements of superior products at least once and met the performance requirements of first-class products another time.
JB/T560371999
4.2.1.3 The enterprise shall have the conditions for stable production of superior products and be able to produce according to the performance requirements of superior products. Among the qualified products, the product shall meet the performance requirements of superior products at least once. The percentage of products that meet the performance requirements of superior products is above 80%. 34.2.2 Necessary conditions for first-class products
4.2.2.1 After the sample test, the product is judged to meet the performance requirements of first-class products according to 4.2.1.1. 4.2.2.2 At the end of the four quarterly type inspections within a year, the product shall meet the performance requirements of first-class products at least three times, and meet the performance requirements of qualified products another time:
4.2.2.3 The enterprise shall have stable working conditions for the production of first-class products, and be able to produce products according to the performance requirements of first-class products. Among the qualified products, the percentage of factory inspection items that meet the performance requirements of first-class products (including superior products) is above 80%: 4.3 Other related requirements shall comply with the provisions of GB/T5591.1. 5 Methods
