Complete ISO 20345 Overview

CERTIFIED STANDARDS FOR SAFETY FOOTWEAR

There are 2 MAIN STANDARDS for safety footwear: ASTM 2413 & EN ISO 20345. Besides these 2 main standards, Safety Jogger pays attention to other safety footwear standards as well (AS/NZS, JIS, LA, SNI, SIRIM, GOST, OHSC) but they are generally based on ASTM & ISO, which are explained below.

› ASTM 2413 - 17

The American Society for Testing and Materials (ASTM) is an international standards organization that develops and publishes voluntary consensus technical standards or certifications. ASTM announced in 2005 that their ANSI Standard was withdrawn and replaced by two new ASTM standards, titled F2413 Standard for Performance Requirements and F2412 Standard for Foot Protection Test Methods. These new safety footwear standards provide safety and performance previously put forward by ANSI since 1967.

The biggest difference with ASTM 2413 conforming safety footwear to other standards is that the outsole must be completely insulated for electric shocks. Other requirements for ASTM 2413 conforming safety footwear are impact / compression resistance for the toe area, puncture resistance for safety shoes, and more.

› EN ISO 20345 - 11

The current safety footwear standard across Europe is updated in 2011 to make it stricter, all products must be manufactured, tested and certified under EN ISO 20345. This safety footwear standard requires all safety shoes to have front foot protection against a 200 joule impact. This is the amount of energy the toe region can absorb before breaking. Under the EN ISO 20345 standard there are different safety classes like S1 or S3 for example. Every safety shoe according to the EN ISO 20345 safety footwear standard will be tested on all possible aspects and will be granted an S-class. Below you can find a complete overview of the minimum requirements for each safety class within the EN ISO 20345 safety footwear standard.
