Overview
ISO 6005:2019 specifies standardized test methods for ski binding screws used to fasten alpine ski bindings to skis. The document defines test assemblies, required apparatus and step-by-step procedures to characterize screw properties such as driving torque, stripping torque, static pull-out strength, ductility and breaking moment. Acceptance criteria themselves are given in ISO 6004; ISO 6005:2019 focuses on reproducible screw test methods for quality control and comparative evaluation.
Key topics and technical requirements
- Test assemblies and materials
- Standard test assembly dimensions: 70 mm × 500 mm, core thickness 20 mm.
- Multi-layer construction representative of ski mounting areas (glass-fibre epoxy laminates, aluminium alloy, ABS, polyurethane foam).
- Bonding and ageing conditions specified for reproducible test specimens.
- Apparatus
- Drill and test jig for precise 4.1 mm H12 holes and perpendicular screw insertion.
- Friction plate, hardened bushing and pull-out apparatus with support rolls for axial tests.
- Test procedures
- Breaking moment: torsional strength per ISO 3506‑4 (stainless steel) and ISO 2702 (other alloys).
- Ductility test: screw driven into fixation, then lateral hammer blows until 10° head deformation.
- Driving torque: drive screw into assembly M (9 mm drill depth), measure torque after each half rotation; record maximum torque; repeat with at least 10 screws.
- Stripping torque: mount in assembly P (7 mm drill depth), apply increasing torque until thread failure; record maximum; minimum 10 samples.
- Static pull-out test: screw at 8 mm penetration, axial loading at 20 mm/min until pull-out; record peak load; repeat on ≥10 screws.
- Reporting
- Test report must include manufacturer, standard reference (ISO 6005:2019), screw designation, maximum stripping and driving torques, pull-out strength and test date.
Applications and who uses it
- Manufacturers of ski bindings and fasteners use ISO 6005:2019 for design validation, production quality control and supplier qualification.
- Test laboratories and certification bodies apply the specified methods to generate repeatable performance data.
- R&D and materials engineers use the test methods to compare screw designs, coatings and materials for durability and safety.
- Retailers and safety auditors can reference standardized test results when assessing product claims.
