What is ISO 22568‑4 about?
PPE footwear needs to offer higher protection than every day-use footwear. ISO 22568‑4 is the fourth part of a multi-series on foot and leg protectors. ISO 22568‑4 specifies requirements and test methods for the non-metallic inserts with resistance against mechanical perforation, intended to function as components of PPE footwear.

ISO 22568‑4 on inserts for PPE footwear is used by:
- Footwear manufacturers
- Footwear component manufacturers

Why should you use ISO 22568‑4?
ISO 22568‑4 on safety, protective and occupational footwear defines the performance and required properties of the footwear.
