T/GLCL 0001-2019 Woven Filter Material

Scope

Main technical content: This standard is based on the national textile industry standard "Woven Filter Fabrics" (FZ/T 64015-2009). In combination with the market demands and practical experience of the industry, some improvements and enhancements have been made. a. The product classification and code are largely based on the national industry standard, with some supplementary content. b. Regarding the internal quality requirements, except for the requirements of breaking strength and elongation at break, more specific requirements and calculation methods have been provided for the strength of filter materials based on the different materials and fiber forms of raw materials used in filters, as well as the different fabric structures. The basic breaking strength requirements of filter materials and the utilization coefficient of fabric breaking strength are included as appendices to the standard. Other index requirements are largely based on the national industry standard. c. The requirements for the appearance quality of products and the inspection methods have been slightly adjusted and improved, and clear provisions have been made for the mandatory inspection items and optional inspection items. d. The judgment of quality inspection results has been made more specific and practical based on actual situations. The formulation of this standard is more detailed and practical than the 2009 industry standard, making it easier to grasp and implement in the production process and market trade process.
