Scope

Main technical content: This standard is based on the PVB industry alliance standard Q/331023LM, and some improvements and enhancements have been made in combination with the industry market demand and practical situation. a. For product classification and codes, the alliance standard is basically adopted, with slight modifications and enrichments to meet market needs. b. For product internal quality requirements, improvements are made in terms of appearance, physical and chemical properties, and mechanical performance. 1. For appearance defects, the number of joints is optimized as an indicator. 2. For internal quality, three indicators including moisture pass rate, heat shrinkage rate, and haze are modified to be more stringent. 3. The impact performance indicator of the scatter bag is deleted, and the ultraviolet transmittance ratio indicator is added. c. For the determination of quality inspection results, clearer regulations are made based on actual situations. The formulation of the above standard is more specific and practical than the 2013 industry standard, and it is easier to grasp and implement in the production process and market trade process.
