ISO 14790:2005

Overview

ISO 14790:2005 - "Snowboard plate-bindings without a release mechanism - Requirements and test methods" defines essential safety, performance and quality requirements for non-releasable snowboard plate bindings for adults and children. It excludes bindings with release mechanisms and soft bindings. The standard prescribes functional criteria, mechanical and fatigue test methods, marking and user/mounting instructions to ensure reliable boot-to-board connection in winter conditions.

Key Topics

• Scope & types
  • Applies to non-releasable plate bindings for adults (Type A) and children (Type C - ≤ 45 kg).
• Functional requirements
  • After testing, bindings must show no fractures/permanent deformation, must retain and release the boot in normal use, and prevent boot slip.
• Mechanical limits & forces
  • Defined torque limits for three axes (x, y, z); e.g. Type A: ±Mx 300 N·m, ±My 550 N·m, ±Mz 150 N·m; Type C values are lower.
  • Loading-rate guidance for quasi-static torque application (torsion, forward and lateral bending).
• Fatigue testing
  • 50,000 sinusoidal cycles at up to 1 Hz in the ±My direction. Test torques: ±100 N·m for adults, ±(66 ± 3.3) N·m for children.
• Environmental & cold testing
  • Mechanical tests include preconditioning at −20 °C and use of cold test soles to verify performance under low temperatures.
• Additional requirements
  • Minimum breaking force for retaining-leash mounting point and leash: 500 N.
  • Binding must latch with a minimum 2 mm snow pack between boot sole and binding.
  • Bindings must be supplied with appropriate mounting screws (preferably M6 class g or per ISO 6004).
• Sampling & measurement
  • Three pairs required for testing; measurement accuracy ±2% for torsion/forward bending.
• Marking and documentation
  • Marking: manufacturer/trademark and max user mass for children’s bindings (45 kg).
  • Required mounting and user instructions (mount points, drill template, boot requirements, maintenance, leash use, antiskid pad guidance).

Applications

ISO 14790:2005 is practical for:

• Manufacturers designing and validating non-releasable snowboard plate bindings
• Independent test laboratories performing compliance and fatigue testing
• Importers, retailers and mount technicians ensuring safe installation and consumer information
• Product safety assessors and regulators specifying minimum performance for non-releasable bindings
