Global Protective Clothing Standards, Explained for Buyers

1. Flame-Resistant (FR) Clothing

Standard	Region	What it proves
EN ISO 11612	Europe / international	Clothing against heat and flame. Code A (limited flame spread) is mandatory; optional codes B (convective heat), C (radiant heat), D/E (molten aluminium/iron splash), F (contact heat). Typical industrial spec: A1 B1 C1.
EN ISO 11611	Europe	Welding and allied processes — Class 1 (lighter) / Class 2 (heavy welding). Required for welders' suits.
NFPA 2112	USA / Canada	FR garments for industrial flash fire — garment-level certification incl. manikin flash-fire testing. Standard for oil & gas, utilities.
ASTM F1506	USA	FR textiles for electric-arc exposure — pairs with NFPA 70E categories (CAT 1–4).

Inherent vs treated FR — the question that decides garment life

Inherent FR fibres (modacrylic blends, aramids) are flame-resistant at fibre level: they never wash out and survive 50–100+ industrial washes. Treated FR (e.g. Proban-treated cotton) meets the same standards when new, but the finish degrades — count industrial washes, not years, and write the wash-cycle rating (typically 50–100) into the tech pack.

2. High-Visibility Clothing

Standard	Region	Key points
EN ISO 20471	Europe / international	Classes set by minimum visible background + retroreflective area: Class 1 (lowest) to Class 3 (highest — motorway/rail work). The garment is certified as a whole: a Class 3 combination loses certification if the compliant trouser/bib is removed. Fluorescent background must pass colour/brightness after xenon fading tests.
ANSI/ISEA 107	USA	Types: O (off-road), R (roadway), P (public safety, NFPA-aligned). Classes 1–3. Many garments carry dual EN ISO 20471 + ANSI 107 certification to serve both markets.

Spec tip: always ask whether the certificate covers the garment or only the fabric. Fabric-level certificates are common; garment-level certification is what tender compliance usually requires.

3. Anti-Static & ESD

Standard	Region	Key points
EN 1149-5	Europe	Material performance + design requirements for explosive atmospheres (ATEX zones). Essential for fuel stations, paint shops, gas plants.
IEC 61340-5-1	International	ESD control program for electronics manufacturing — garments as part of a floored, wrist-strapped system, not a standalone claim.

4. Chemical, Cold & Rain

Standard	What it proves
EN 13034 (Type 6)	Light spray/liquid chemical protection — reusable suits for splash risk.
EN 14605 (Type 3/4)	Liquid-tight (3) or spray-tight (4) chemical suits.
EN 342	Cold protection as a system (garment + layers), rated by resultant effective temperature (e.g. comfort to −40 °C), via insulation (Icler) and air-permeability classes.
EN 343	Rain protection — waterproofness and breathability classes (e.g. 3/3).

5. How to Specify Without Overpaying

1. Start from the hazard, not the product. Welding → EN ISO 11611 Class 2 + EN ISO 11612; EU road crew → EN ISO 20471 Class 2 minimum (Class 3 for high-speed roads); US oil & gas → NFPA 2112 + ASTM F1506 by CAT level.
2. Ask for the certificate, then read it. Check the holder (must be the mill, garment maker or authorized brand — never a company borrowing someone else's), scope (fabric vs garment), dates, and lab accreditation (ISO/IEC 17025).
3. Match wash rating to your laundry cycle. Industrial laundry at 75 °C finishes faster than home-laundry claims — put the wash-cycle warranty in writing on the tech pack.
4. Dual-certify only when you sell both markets. EN + ANSI dual labels add testing cost; pure-EU volume doesn't need ANSI.
5. Test reports travel with the lot. Make the lot-specific test report a purchase-order line item.
