This document specifies requirements and test methods for the non-metallic inserts with resistance against mechanical perforation, intended to function as components of PPE footwear (e.g. as described by ISO 20345, ISO 20346 and ISO 20347).
Abstract
Overview
ISO 22568-4:2021 specifies requirements and test methods for non-metallic perforation resistant inserts used as components of PPE footwear (for example in footwear conforming to ISO 20345, ISO 20346 and ISO 20347). The standard defines how to evaluate mechanical perforation resistance, flexing durability, environmental stability and (optionally) electrical resistance of inserts intended to protect the foot and sole from sharp objects.
Key topics and technical requirements
- Perforation resistance (Types PL and PS)
- Type PL: tested with a conical nail of 4.5 mm diameter (Method PL, Annex A). All four reported results must “pass” at 1100 N and no “tent effect” is allowed.
- Type PS: tested with a conical nail of 3.0 mm diameter (Method PS, Annex B). The average perforation force must be ≥ 1100 N, and **no single value may be
