ISO 20347:2021/Amd 1:2024 is the latest amendment to the international standard covering personal protective equipment for occupational footwear. This amendment updates requirements and testing methods to enhance safety, comfort, and performance of work shoes designed for various industrial and commercial environments. Developed by ISO Technical Committee ISO/TC 94 and European Committee for Standardization CEN/TC 161 under the Vienna Agreement, this document ensures harmonized global standards for occupational footwear compliance.
Key updates improve material specifications, water vapor permeability, tear resistance, and electrical properties, ensuring occupational footwear meets modern workplace safety demands. This amendment supports manufacturers, safety professionals, and users focusing on footwear that protects while promoting wearer comfort.
Normative References Update Incorporates the latest ISO 20344:2021+Amd.1:2024 testing standard, reflecting new testing protocols for occupational footwear.
Material Performance Enhancements Increased requirements for tear strength and water vapor permeability in footwear uppers improve durability and breathability, essential for prolonged workplace wear.
Water Vapor Permeability & Coefficient Footwear must comply with specific permeability levels depending on the proportion of non-permeable material, optimizing foot comfort by reducing moisture build-up.
Chromium VI Content Limits Leather components are required to have chromium VI contents below 3.0 mg/kg, ensuring compliance with health and environmental safety regulations.
Design and Construction Specifications Defines classification and height requirements for hybrid footwear materials, clarifying performance expectations between different material zones.
Electrical and Antistatic Properties Details guidance on antistatic footwear usage to minimize electrostatic build-up, emphasizing the need for regular performance testing and environmental compatibility. Specifies that the standard does not cover electrically insulating footwear, which falls under EN 50321-1:2018.
Mechanical Resistance and Durability Tests Updates to cutting, flexing, and bonding resistance tests for outsoles and multi-layer constructions ensure occupational footwear maintains integrity under demanding conditions.
Scuff Cap Requirements New ergonomic testing mandates scuff caps effectively prevent upper-ground contact during kneeling, enhancing protection and durability.
ISO 20347:2021/Amd 1:2024 is essential for manufacturers designing and producing occupational footwear that conforms to stringent international safety criteria. Key application areas include:
Industrial Workforces Footwear for manufacturing, construction, logistics, and warehousing that demands protection from mechanical hazards and chemical exposure.
Healthcare and Laboratory Settings Ensures footwear provides chemical resistance and is free from harmful chromium VI contamination, protecting health professionals.
Electronics and Flammable Environments Antistatic footwear adapted for environments where electrostatic discharge could pose explosion or equipment damage risks.
Ergonomic Use Cases Innovations such as scuff caps enhance protection for workers frequently kneeling or performing repetitive movements, reducing injury risk.
Safety officers and compliance managers rely on this amendment to align workplace footwear protocols with international standards, promoting workforce safety and operational efficiency. Manufacturers benefit from clear guidelines on material and design requirements, facilitating global market access.
ISO 20344:2021+Amd.1:2024 - Specifies test methods for protective footwear, referenced throughout the amendment for performance validation.
