SIST EN ISO 22653:2018 PDF

Overview

EN ISO 22653:2018 - Footwear: Test methods for lining and insocks - Static friction (ISO 22653:2003) specifies laboratory methods to assess the frictional properties of footwear linings and insocks, regardless of material. Adopted by CEN in 2018, this standard reproduces ISO 22653:2003 and supersedes EN 12826:2000. It defines two complementary test approaches to quantify static friction, kinetic friction, and related angles of surface drag for lining and insole materials.

Key topics and technical requirements

• Scope and definitions
  • Defines coefficient of static friction (μs), coefficient of kinetic friction (μk), static angle (Ds) and kinetic angle (Dk) of surface drag.
• Two test methods
  • Method A - Flat bed (sled) method
    • Uses a sled (150 × 100 mm, mass ~700 g) with the lining/insock specimen attached.
    • Comparator material fixed to a flat bed; drive mechanism maintains relative travel at 800 mm/min ± 80 mm/min.
    • Force to initiate movement and to maintain constant velocity recorded via strain gauge/autographic recorder (response time
