Overview
ISO 8783:2015 - Alpine skis: Guidelines for conducting slope performance tests gives standardized guidance for comparative, on-slope performance testing of alpine skis. Intended to evaluate ski performance characteristics objectively and reproducibly, the standard applies to alpine skis manufactured in accordance with ISO 6289. It combines subjective expert assessment with statistical support to ensure reliable, comparable test results for ski models.
Key topics and requirements
- Test principle: Comparative rating by competent test personnel supported by sufficient individual results to allow statistical analysis and reproducibility.
- Test conditions: Tests are carried out on the same terrain for all testers, in hard, well-prepared snow; skis of the same category should be tested within a single day unless snow conditions change.
- Test personnel: Testers must be independent, neutral experts with adequate skiing and assessment ability, trained on the evaluation criteria and rating system.
- Test committee: Supervision by a committee of at least three technical experts plus a test supervisor; majority vote determines testing adequacy.
- Test skis and preparation:
- Skis must be typical of the model and tested as delivered (unless manufacturer-recommended treatment is applied).
- Running surfaces cleaned and uniformly waxed for prevailing snow conditions.
- No prior use of test skis before the official test; damaged skis removed for refurbishment.
- Criteria and rating:
- Core evaluated characteristics: movement (turnability), edge grip, steering behaviour, stability, quietness, skier friendly/ski character.
- Use of reference skis for comparison and a five-grade rating scale: very good, good, satisfactory, poor, very poor.
- Bindings and tuning: Test with manufacturer-recommended bindings; optional tuning or additional elements can be tested as sold or in separate tests.
- Test report and publication:
- Required report elements: reference to , test conditions, ski descriptions and lengths, individual ratings, total scores and standard deviations, and noted deviations (e.g., tester weight).
