The production qualification standards for industrial filter cloth are mainly carried out in accordance with relevant national and industry standards. The following are some common standards and specifications:

GB/T 26333 Quality Requirements and Test Methods for Filter Cloth: This standard specifies the quality requirements for filter cloth, including six aspects: mechanical properties, pollution analysis, anti-aging performance, softness, non-toxic ingredients and fineness. In addition, requirements for the size, surface treatment, processing technology, dyes, and waterproofing of the filter cloth are also specified.

HG/T 21618 "Chemical Filter Cloth" and HG/T 21574 "Pharmaceutical Filter Cloth": These two standards specify the classification, requirements, test methods, marking, packaging, transportation, and storage requirements for chemical and pharmaceutical filter cloths.

ISO 2942 "Acceptance and Inspection of Hydraulic Filter Components": This international standard specifies the acceptance and inspection methods for hydraulic filter components, including requirements for the size, material, filtration accuracy, pressure loss, hydrophobic performance, and other aspects of the components.

FZ/T 64015-2009 "Machine woven filter cloth": This standard specifies the classification, technical requirements, test methods, inspection rules, marking, packaging, transportation, and storage of machine woven filter cloth.

GB/T 5542-2007 "Determination of large particles of dyes - Single layer filter cloth filtration method": This standard specifies the method of using single-layer filter cloth filtration method to determine large particles of dyes.

GB/T 24119-2009 "Determination of Water Permeability of Woven Filter Clothes" and GB/T 24219-2009 "Determination of Bubble Point Aperture of Woven Filter Clothes": These two standards respectively specify the methods for determining the water permeability and bubble point aperture of woven filter fabrics.

These standards and specifications provide clear requirements and guidance for the production qualification of industrial filter fabrics, helping to ensure that the quality and performance of filter fabrics meet the needs of the industry and users. With the continuous advancement of technology and changes in market demand, these standards will also be updated and revised accordingly to adapt to new challenges and opportunities.
