Canvas Shoes, Rubber Sole — Specification (Third Revision)

This Indian Standard outlines the technical requirements, testing methods, and quality parameters for canvas shoes with rubber soles, commonly used for sports, physical training, and general wear.

Updated as the third revision, it incorporates all previous amendments, aligns test methods with updated IS/ISO standards, and aligns the requirements with current manufacturing practices. The standard introduces two types of canvas shoes—Type 1 and Type 2 —and prescribes detailed requirements for materials such as upper fabrics, linings, bindings, laces, eyelets, and rubber components. Fabric strength parameters like breaking load, ends and picks per decimetre, and colour fastness are clearly specified to ensure durability and consistent performance. Rubber components, including soles, heels, foxing, and toe-caps, must meet strict criteria for hardness, flexing resistance, tensile strength, ageing resistance, abrasion, and slip performance.

Construction provisions cover stitching quality, reinforcement, foxing dimensions, toe-cap design, and overall workmanship to ensure robust, comfortable footwear. Mandatory performance tests—such as adhesion, consolidation, seam strength, slip resistance, and banned azo dye detection — ensure user safety and product reliability. Mass limits are also prescribed for uniformity across sizes.

This further details packing and marking requirements, including size, type, and manufacturer identification, along with eligibility for BIS Standard Mark certification. Comprehensive sampling criteria are provided to verify conformity within consignments. Through these measures, the standard strengthens quality control, enhances user safety, and promotes uniform, dependable manufacturing of canvas shoes across the industry.
