ISO 11088:2023

Overview

ISO 11088:2023 - "Alpine ski/binding/boot (S‑B‑B) system - Assembly, adjustment and inspection" provides practical, shop‑level procedures for assembling, adjusting and inspecting alpine ski binding mechanisms as part of a complete ski‑binding‑boot (S‑B‑B) system. Intended primarily for retailers and ski technicians, the standard integrates requirements from related international standards and applies when at least one component of the S‑B‑B system is owned by the user, or for systems rented for 15 days or more.

Key technical topics and requirements

• Scope and applicability: Procedures apply to complete and incomplete S‑B‑B systems owned by the user or rented ≥15 days (ISO 13993 covers rentals <15 days).
• Skier parameters: Determination of skier mass, height, age, boot sole length and skier type (see Annex A) to select individual release values in accordance with ISO 8061.
• Release values and tolerances:
  • Selected individual release value defined per ISO 8061.
  • Inspection range: measured release value must be within ±15% of the selected value, or ±3 Nm (twist) / ±10 Nm (forward lean), or one row on manufacturer chart - whichever is greater.
  • Re‑adjustment range: corrective actions allowed up to ±30% (or ±6 Nm twist / ±20 Nm forward lean).
• Assembly & mounting:
  • Follow binding and ski manufacturer instructions; recommended drilling practices (Annex E); new holes min. 10 mm from old holes; maximum screw tightening typically 4 Nm unless specified otherwise.
• Compatibility & fitting:
  • Boot‑binding compatibility checks and Table 1 marking guidance (ISO 5355, ISO 23223, ISO 9523 compatibility).
  • After sole pad replacement, perform release tests and re‑marking where applicable.
• Functional checks & measurement:
  • Initial indicator adjustment (binding manufacturer tables), functional inspection, measurement of release values (clause 6.7) and reporting (clause 6.8).
• Annexes: normative flowchart (Annex C), setting method (Annex B), diagnostic tests (Annex D) and drilling guidance (Annex E).

Practical applications - who uses ISO 11088:2023

• Ski retailers and fitters performing shop assembly, adjustment and inspection.
• Rental shops managing equipment rented ≥15 days.
• Ski service technicians verifying release values and compatibility after repairs or sole replacement.
• Technical trainers and quality assurance personnel establishing shop procedures.
• Manufacturers and importers for aligning product instructions with shop practice.
