Full title and description

ST ISO 20471-2013 amd1-2016 — Officially published as ISO 20471:2013/Amd 1:2016, "High visibility clothing — Test methods and requirements — Amendment 1". This amendment applies to ISO 20471:2013 and provides a short technical/editorial update to the original high‑visibility clothing standard.

Abstract

ISO 20471 specifies requirements and test methods for high‑visibility clothing intended to visually signal the user’s presence to vehicle operators and other mechanized equipment operators in daylight and under vehicle headlight illumination. Amendment 1 (2016) is a published one‑page amendment to the 2013 edition that clarifies or corrects points in the original document.

Scope

ISO 20471:2013 (with Amendment 1:2016) covers high‑visibility clothing designed to provide conspicuity of the wearer in daylight and under vehicle headlights in dark conditions. It sets performance requirements for fluorescent (background) materials and retroreflective materials, minimum visible areas and placement rules, and associated test methods for colour, photometric performance and durability. Amendment 1 is a short, technical/editorial change that applies to and updates the 2013 text.

Key topics and requirements

• Performance requirements for fluorescent (background) materials and retroreflective materials (photometric and colourimetric tests).
• Garment classification into three protection classes (Class 1, Class 2, Class 3) determined by minimum visible areas of fluorescent and retroreflective materials. Example minimums: fluorescent — Class 3: 0.80 m², Class 2: 0.50 m², Class 1: 0.14 m²; retroreflective — Class 3: 0.20 m², Class 2: 0.13 m², Class 1: 0.10 m².
• Requirements for placement and 360° visibility (bands/arrangements to ensure visibility from front, back and sides).
• Durability and conditioning tests (including wash/dry cycles, ageing and simulated use) to verify retained colour and retroreflective performance after care procedures.
• Marking and user information (class identification, colour/retroreflective performance, and guidance on maximum wash cycles or expected durability).

Typical use and users

The standard is used by PPE manufacturers, product designers, conformity assessment bodies, test laboratories, procurement specialists and safety managers to design, test, specify and certify high‑visibility garments for highway/road works, rail, emergency services, construction, utilities, ports, and other high‑risk situations where conspicuity is critical. It is also used by regulatory bodies and employers when selecting garments for tasks that expose workers to vehicle traffic or moving equipment.

Related standards

Commonly associated standards and references include the parent ISO 20471:2013 main publication, national/adopted variants (for example EN ISO 20471 in Europe), the replaced EN 471 legacy standard, and other high‑visibility specifications such as ANSI/ISEA 107 (United States). ISO 20471 is part of the PPE family of standards and is referenced alongside general PPE requirements (e.g., ISO 13688) and regional adoptions.

FAQ

Q: What is this standard?

A: ISO 20471:2013 is the international standard that specifies test methods and performance requirements for high‑visibility clothing; ISO 20471:2013/Amd 1:2016 is Amendment 1 to that 2013 standard (a short technical/editorial amendment published in October 2016).

Q: What does it cover?

A: It covers the colours and photometric performance of fluorescent and retroreflective materials, minimum visible areas, placement/garment design rules to ensure 360° conspicuity, durability and conditioning tests (including wash/ageing), and labeling/user information required for conformity.

Q: Who typically uses it?

A: PPE manufacturers, test laboratories, certification bodies, safety managers, procurement officers, and regulators use this standard to design, test, certify, buy and mandate high‑visibility garments for workers in road, rail, emergency response, construction and other high‑risk environments.

Q: Is it current or superseded?

A: As of the amendment publication, ISO 20471:2013 plus Amendment 1 (2016) is the active published text. ISO maintains lifecycle information and periodic review; users should check national adoption or the ISO catalogue for any later revisions or a revised edition (ISO has had follow‑on work and draft activity noted in ISO lifecycle records). For authoritative purchase or confirmation consult the ISO publication records.

Q: Is it part of a series?

A: ISO 20471 is part of the protective clothing/PPE standards family (managed by ISO/TC 94/SC 13) and is frequently paired with regional implementations (EN ISO 20471) and other PPE standards such as ISO 13688 (general requirements). Amendment 1 is explicitly an update to the 2013 edition rather than a standalone new edition.

Q: What are the key keywords?

A: High‑visibility, retroreflective, fluorescent, PPE, ISO 20471, garment classes (Class 1/2/3), conspicuity, photometric tests, durability, amendment 2016.
