ISO 20471:2013/Amd 1:2016

Overview

ISO 20471:2013/Amd 1:2016 is an important amendment to the international standard for high visibility clothing, specifically detailing updated test methods and requirements. Published by the International Organization for Standardization (ISO), this amendment enhances the original ISO 20471:2013 edition, ensuring that clothing designed for enhanced visibility meets rigorous safety and performance criteria.

This standard is developed by ISO Technical Committee ISO/TC 94, Subcommittee SC 13, which focuses on personal protective equipment, including high visibility garments. The amendment refines specific testing procedures to ensure that such clothing performs reliably in various occupational and environmental conditions.

Key Topics

• High Visibility Clothing Safety: The standard specifies requirements to maximize the wearer's visibility in various light conditions, which is crucial for safety in workplaces such as construction sites, roadworks, and emergency response.

• Test Methods: ISO 20471:2013/Amd 1:2016 introduces refined test procedures for high visibility clothing, including abrasion resistance protocols. A revised approach to abrasion testing incorporates positioning of test specimens and abrasive materials for more accurate and reproducible results.

• Abrasion Resistance: The amendment clarifies the testing sequence where test specimens must be placed on the abrasion table while the abrasive material is held in the specimen holder. This minor but critical modification ensures more reliable abrasion patterns that allow for post-abrasion testing, helping evaluate garment durability.

• Compliance and Certification: By complying with this amendment, manufacturers and certifiers can ensure their products meet internationally accepted safety and quality standards, supporting global trade and user safety.

Applications

The standard and its amendment are highly applicable in sectors requiring garments that ensure worker safety through high visibility:

• Construction and Roadwork: Workers benefit from garments meeting ISO 20471:2013/Amd 1:2016 to remain conspicuous near heavy machinery and traffic.

• Public Safety and Emergency Services: Police officers, fire fighters, and rescue teams use certified high visibility clothing to sustain operational safety during critical missions.

• Industrial and Transport Operations: Workers in warehouses, airports, and logistics roles are protected by garments that conform to this standard, reducing accident risks.

• Manufacturing and Quality Assurance: Textile and apparel manufacturers integrate these testing methods into their quality control systems to verify the durability and performance of high visibility clothing.

Related Standards

ISO 20471:2013/Amd 1:2016 forms part of a suite of standards governing protective clothing and personal safety equipment, including:

• ISO 20471:2013 (Base standard on high visibility clothing requirements and test methods)
• ISO 12947-2 (Textile abrasion testing methods, referenced for abrasion test clarifications)
• ISO/TC 94 Series (Broader standards on personal protective equipment for individual safety)
• IEC/ISO Directives (Framework documents guiding the development and revision of international standards)

Practical Value

Adherence to ISO 20471:2013/Amd 1:2016 ensures that high visibility garments not only meet functional visibility requirements but also pass stringent durability tests such as abrasion resistance. This results in clothing that maintains its safety features throughout its service life, reducing accidents and improving occupational safety worldwide.

Manufacturers and safety managers benefit from incorporating these updated test methods into product design and evaluation-improving product reliability, compliance, and user confidence in critical safety apparel.
