The updated ISO 28017:2026 standard establishes comprehensive requirements for wire- or textile-reinforced rubber hoses used in demanding dredging environments, with nominal sizes from 100 to 1300 mm. Dividing hoses by type (floating or submarine), class (based on working pressure), and grade (focused on construction and reinforcement), the standard addresses hoses for both suction and delivery of water mixtures containing silt, sand, coral, or stones.

Scope and Highlights:

• Details types (floating for delivery, submarine for suction/delivery) and available classes/grades (including low temperature “-LT” variants).
• Specifies construction, lining and cover material thickness, and robust end fittings.
• Sets physical and mechanical performance requirements (e.g., hydrostatic pressure, bending, abrasion resistance, and minimum reserve buoyancy for floating hoses).
• Lays out marking, documentation, and packaging/storage recommendations.

Key changes from previous versions include revised ambient temperature ranges, a new larger nominal size (1300 mm), and additional brittleness requirements for low-temperature hoses. This update is crucial for marine engineering firms, dredging operators, and hose manufacturers supplying to global infrastructure projects.

Key highlights:

• Coverage for two hose types, seven pressure classes, and three grades
• Enhanced mechanical and physical testing protocols
• Updates for low-temperature performance and larger diameters
