ISO 17357-2:2014 specifies requirements for low-pressure floating pneumatic rubber fenders (initial pressure typically 7 kPa), including clamped end type (≤2.3m diameter) and moulded end type (≥2.8m diameter). It defines material specifications, performance criteria (GEA at 60±5% deflection), dimensional tolerances, and essential tests (air leakage ≤10 mbar/60min, durability, compression recovery). The standard ensures fenders safely absorb berthing energy while maintaining structural integrity in marine environments.
