ISO 11393-6:2018

Overview - ISO 11393-6:2018 (Protective clothing for chainsaw users - upper body protectors)

ISO 11393-6:2018 specifies performance requirements and test methods for upper body protectors intended to reduce the risk of cutting injuries from hand-held chainsaws. The standard covers design, sampling and pre-treatment, measurement of protective coverage, apparatus and procedures for cutting-resistance testing, ergonomic performance tests, marking and manufacturer information. Annex A provides guidance on chainsaw use and selection of appropriate upper body protectors.

Key technical topics and requirements

• Performance requirements: general safety, innocuousness (no harmful effects from materials), sizing and ergonomic features to ensure practical wearability and protection.
• Protective coverage: defined minimum areas for front, rear and sleeve designs (multiple jacket designs A and B), including optional collar coverage and rules for fastenings and joins.
• Resistance to cutting: test methods and apparatus to assess how the protective material behaves on chain contact - including classification according to chain speed.
• Sampling and pre-treatment: procedures for cleaning and pre-treating garments prior to testing (including a 60 °C spin-drying pre-treatment when applicable) to evaluate dimensional and other changes caused by maintenance.
• Dimensional and durability testing: methods to measure dimensional change and other alterations after cleaning or thermal/spin pre-treatment.
• Ergonomic testing: practical performance tests to evaluate mobility, surface conditions and wearer comfort.
• Attachment and closure strength: tests for secure fixing of padding and durability of closures (zips, buttons, fasteners).
• Marking and information: mandatory labelling, pictogram and manufacturer-supplied information for correct selection and use.

Practical applications - who uses ISO 11393-6:2018

• PPE manufacturers developing upper body protectors for forestry, arboriculture, utility work and landscaping.
• Test laboratories and certification bodies conducting standardized cutting-resistance and ergonomic tests.
• Procurement and safety managers selecting compliant chainsaw protective clothing for field crews.
• Regulators and auditors assessing workplace PPE compliance and conformity with international test methods.
• Designers and R&D teams optimizing the balance of protection, comfort and durability in chainsaw PPE.
