Topic | Comparing international PPE-standard scopes: general clothing, welding, high visibility, and occupational footwear

ISO 13688, ISO 11611, ISO 20471, and ISO 20347 address different clothing or PPE topics. This topic compares scope rather than ranking standards, helping teams avoid using one standard to cover every work risk.

Source-backed points

• ISO 13688 covers general protective-clothing requirements and says it should be combined with specific-performance standards.
• ISO 11611 addresses clothing for welding and allied processes.
• ISO 20471 focuses on high-visibility clothing, while ISO 20347 addresses general-purpose occupational footwear.

Editorial context

The most common procurement misuse is stacking standard numbers. A better method defines risk and task first, then identifies product standards, general requirements, combination compatibility, and management procedure for each PPE element.

Use boundary and next step

• Create a risk–PPE body area–standard scope–verification file matrix.
• Ask competent people to review cross-standard references and applicability.
