Description (English):

This document specifies requirements and test methods for assessing the resistance to cutting of gaiters by hand-held chainsaws and other properties. It includes a requirement and a test method for assessing the strength of underfoot straps of gaiters. This document is applicable to gaiters used in conjunction with safety footwear with a steel toecap conforming to ISO 20345 design "C" or "D". These gaiters are designed to be used only in association with a defined model of footwear and tested together. NOTE These products are intended, but are not limited, to be used in combination with a defined model of orthopaedic footwear. This document does not apply to gaiters intended for use in situations where there is a significant risk of tripping, such as tree climbing or in forests.

Abstract

Overview

ISO 11393-5:2018 specifies performance requirements and test methods for protective gaiters intended to reduce the risk of cutting from hand‑held chainsaws. The standard covers gaiters worn over safety footwear (with a steel toecap conforming to ISO 20345 design “C” or “D”) and requires gaiters to be tested together with a defined model of footwear. It is focused on assessing cut resistance, attachment strength, twisting resistance, ergonomics and innocuousness of materials. Note: ISO 11393-5 does not apply to gaiters for activities with a significant tripping risk (e.g., tree climbing or certain forest work).

Key topics and technical requirements

Cut resistance and test methods: Gaiter-plus-footwear systems are tested for resistance to cutting by a chainsaw; the system must show no cut‑through under the specified test conditions.
Classification by chain speed: Protection classes are defined for three chain speeds - 20 m/s (class 1), 24 m/s (class 2), and 28 m/s (class 3).
Attachment system strength: The underfoot strap and fastening (attachment system) shall not fail below 250 N when tested.
Twisting resistance: After loading and release, maximum twisting displacement must be ≤ 10 mm in the direction of force.
Specified protective area: The protective material must cover a defined area of the boot including at least 15 mm overlap over the back of the toecap.
Ergonomics and adjustability: Gaiters must minimise movement restriction and score ≤ 2 on the standard’s ergonomic assessment; adjustment systems must not become incorrectly set without the wearer’s knowledge.
Innocuousness and cleaning: Materials must not release harmful substances (per ISO 13688:2013) and, where applicable, pre‑treatment (cleaning) shall follow manufacturer instructions.

Practical applications and users

ISO 11393-5 is used by:

PPE manufacturers designing and certifying gaiters for chainsaw users.
Test laboratories performing chainsaw cut‑resistance, attachment and ergonomic testing.
Safety managers and procurement specialists specifying compliant gaiters for forestry, arboriculture and utility work where foot/ankle protection against chainsaw contact is required.
Orthopaedic footwear producers who supply defined boots to be tested in combination with gaiters. The standard helps ensure products provide a validated level of foot and lower‑leg protection against chainsaw contact while meeting usability and safety criteria.
