Introduction<\/h1>\n

Semirigid Polyurethane Soles are widely used in footwear manufacturing because of their combination of strength, flexibility, cushioning and resistance to everyday wear. They are used in different types of footwear where a durable and properly finished sole is required.<\/p>\n

For manufacturers producing semirigid polyurethane soles in India, compliance with the applicable Indian Standard is important for maintaining consistent product quality and meeting applicable certification requirements.<\/p>\n

IS 13893:1994 \u2013 Semirigid Polyurethane Sole \u2013 Specification<\/strong> specifies requirements for semirigid polyurethane soles used in footwear applications.<\/p>\n

Qualitance India provides BIS Certification Consultancy for Polyurethane Sole, Semirigid as per IS 13893:1994<\/strong>, including assistance with product assessment, documentation, testing, BIS application and factory inspection preparation.<\/p>\n

      • Flexing behaviour<\/li>\n
      • Sole construction<\/li>\n
      • Workmanship<\/li>\n
      • Appearance<\/li>\n<\/ul>\n

        The exact requirements and applicable test methods should be confirmed against the current provisions of IS 13893:1994.<\/p>\n

        \n

        Product Requirements<\/h1>\n

        Semirigid Polyurethane Soles should conform to the applicable requirements specified in IS 13893:1994.<\/p>\n

        Important characteristics may include:<\/p>\n

        Dimensions<\/h3>\n

        The sole should conform to the specified dimensions and permissible tolerances.<\/p>\n

        Hardness<\/h3>\n

        The sole should have the required hardness suitable for its intended footwear application.<\/p>\n

        Density<\/h3>\n

        Density is an important property affecting weight, cushioning and performance.<\/p>\n

        Tensile Properties<\/h3>\n

        The material should have suitable tensile characteristics as required by the standard.<\/p>\n

        Abrasion Resistance<\/h3>\n

        The sole should demonstrate adequate resistance to wear under applicable test conditions.<\/p>\n

        Flexing Performance<\/h3>\n

        The sole should be capable of withstanding repeated flexing without unacceptable deterioration.<\/p>\n

        Workmanship<\/h3>\n

        The finished sole should be properly moulded and free from unacceptable defects.<\/p>\n

        Appearance<\/h3>\n

        The surface should have a satisfactory finish and should be free from defects that could affect its performance or appearance.<\/p>\n

        \n
