ISO 11393-4:2018

Overview

ISO 11393-4:2018 specifies performance requirements and test methods for gloves that protect against cutting by hand‑held chainsaws. Part of the ISO 11393 series on protective clothing for chainsaw users, this standard covers design requirements, protective coverage, test specimens, chainsaw cut tests, ergonomic assessment, marking and manufacturer information. Annex A provides guidance on chainsaw use and selection of appropriate gloves.

Keywords: ISO 11393-4, chainsaw protective gloves, performance requirements, test methods, PPE, chainsaw safety

Key topics and technical requirements

• Scope and definitions: Defines terms such as back of the hand, protective material, protective coverage, mitts and line of longest length to ensure consistent testing and classification.
• Designs and types: Specifies two glove types (Type 1: protection in both hands; Type 2: protection in left-hand glove only) and two designs (Design A and Design B) with required protective areas.
• Performance requirements:
  • Protection against general mechanical risks (aligned with glove standards for abrasion/tear/cut resistance).
  • Specific chainsaw cut resistance classification and requirements based on chain speed and test outcomes.
  • Ergonomic requirements and hand dexterity limits to ensure gloves remain functional and safe to use.
• Test methods:
  • Use of the ISO 11393-1:2018 test rig (flywheel-driven) for chainsaw cut tests.
  • Mounting gloves on left/right artificial hands and defined procedures for cleaning, mounting and cutting operations.
  • Assessment of protective coverage and cut‑through criteria to determine conformity.
• Marking and information: Requirements for marking, pictograms and manufacturer-supplied information to support correct glove selection and use.

Practical applications

• Design and validation of chainsaw protective gloves by manufacturers to meet internationally recognized performance criteria.
• Independent laboratory testing and certification for cut resistance and ergonomic performance.
• Procurement specifications for occupational safety professionals, forestry operations, arborists and tree surgeons seeking PPE that meets ISO criteria.
• Guidance for safety managers and trainers on glove selection, risk assessment and safe chainsaw practices (see Annex A).

Who uses this standard

• PPE manufacturers and product designers
• Conformity assessment bodies and testing laboratories
• Occupational health & safety (OHS) managers, procurement teams
• Forestry contractors, arborists and tree surgery services
• Regulators and standards committees
