Iso 13857 Today

anthropometric data (human body measurements). It addresses three primary reaching scenarios: Reaching Over: How high a fence needs to be based on its distance from the hazard. Reaching Through: How far a hazard must be from a guard based on the size of the opening (slots, squares, or round holes). Reaching Under: Distances to prevent lower limb access. Key Takeaways for Engineers and Safety Managers Opening Size Matters: A slot wide enough for a finger requires a much smaller standoff distance than an opening that admits a whole arm. For example, slot openings larger than 180mm or round openings over 240mm are considered to permit full body access. The 95th Percentile: The values in the standard are selected to cover 95% of the population. However, it's worth noting that individuals with "extreme dimensions" might still be able to reach hazard zones, which is why a thorough risk assessment remains critical. Integrated Design: ISO 13857 is intended to be used with protective structures like guards or impeding devices. It is now more closely aligned with

It does apply to:

However, for static guards, derived from anthropometric data (5th percentile adult female to 95th percentile adult male). iso 13857
