ISO 20344 specifies the fundamental test procedures used to evaluate the performance and safety of protective, safety, and occupational footwear. It does not set the safety requirements themselves; rather, it provides the "how-to" for tests referenced by other standards like ISO 20345 (safety footwear) and ISO 20347 (occupational footwear).
