IEC 63458-2:2026 pdf download,High pressure water jet machines – Safety – Part 2: High pressure hoses, hose lines and connectors.
IEC 63458-2:2026 is an international safety standard that forms Part 2 of the IEC 63458 series, specifically addressing high-pressure hoses, hose lines, and connectors for high-pressure water jet machines. It focuses on mitigating severe hazards such as hose rupture, leakage, and connector failure, which can cause serious injury or equipment damage in industrial cleaning, cutting, and surface preparation applications.
The standard applies to components operating at pressures typically exceeding 250 bar, defining mandatory requirements for material selection, mechanical strength, pressure resistance, temperature tolerance, and compatibility between hoses and connectors. It specifies design criteria for robust construction, including reinforcement layers, corrosion resistance, and resistance to fatigue under repeated pressure pulsations.
Key provisions cover type testing, production testing, and marking requirements, ensuring components meet minimum safety margins (e.g., burst pressure at least 2.5 times the rated working pressure). It also mandates guidelines for safe assembly, installation, maintenance, and replacement, addressing factors like minimum bend radius, torque limits for connectors, and inspection intervals to prevent degradation in service.
As a critical complement to Part 1 (general machine safety), this standard provides manufacturers, installers, and users with a unified global framework to ensure the reliability and safety of high-pressure fluid transfer systems, reducing risks in high-pressure water jetting operations worldwide.
