Overview
ISO 13993:2019 - "Rental ski shop practice - Sampling and inspection of complete and incomplete alpine ski‑binding‑boot systems in rental applications" - specifies a uniform method for sampling and inspecting alpine ski/ binding/ boot systems used in rental operations. It covers both complete systems (all components supplied by the rental facility) and incomplete systems (customer‑owned boots or skis/bindings). The standard excludes alpine touring systems and equipment rented for 15 days or more. ISO 13993 is intended to help rental shops perform consistent functional checks to reduce the risk of binding‑related injuries while clarifying that compliance does not guarantee injury prevention.
Key topics and requirements
- Scope and definitions: clear terminology for system, complete/incomplete systems, reference boot/binding, interchangeability, test device and more.
- Range classes: classification of acceptable deviation and re‑adjustment tolerances (Range class I, II, III). Note: Range class I has special treatment for children’s bindings (reference moment example cited).
- Preseason vs in‑season inspection: distinct procedures for preseason checks (including a simplified option when inventory components are unused) and routine in‑season sampling.
- Sampling requirements: rules for sample size, sampling frequency, random sampling, and how to handle deviations.
- Inspection procedures: step‑by‑step checks for boots and bindings, preconditioning for tests, lubrication testing and evaluation, measurement of release moments using compliant test devices.
- Test and measurement: use of ISO‑compliant test devices (ISO 11110) to determine measured release moment, comparison to selected reference moment, and calculation of correction values and accepted tolerances.
- Reporting and corrective action: documentation of test results, troubleshooting and actions (repair, replacement, readjustment).
Applications and users
ISO 13993 is primarily for:
- Ski rental shops and rental operators
- Ski shop technicians and workshop managers
- Ski area safety officers and quality managers
- Organizations that need a standardized approach to sampling, testing and documenting binding/boot safety in short‑term rental contexts
Practical uses include establishing an inventory inspection program, training rental staff on interchangeable vs non‑interchangeable systems, defining sampling plans by rental skier day, and applying consistent re‑adjustment and corrective procedures.
