Overview
SIST EN ISO 28017:2026 sets out the specifications for rubber hoses and hose assemblies, either wire- or textile-reinforced, for use in dredging applications. Developed by CEN in cooperation with ISO, this international standard covers hoses with nominal sizes from 100 to 1,300 mm. The hoses are designed for transporting seawater or freshwater mixed with silt, sand, coral, and small stones, with a specific gravity from 1.0 to 2.3, at temperatures between -10°C and +40°C or -20°C to +40°C for low-temperature variants. SIST EN ISO 28017:2026 ensures safety, reliability, and product compatibility for floating and submarine dredging hoses.
Key Topics
-
Scope and Classification
- Two primary types:
- Type 1 (Floating Hoses): Equipped with flotation material for delivery applications where buoyancy is necessary.
- Type 2 (Submarine Hoses): Designed for both delivery and suction, suitable for submerged use.
- Seven classes defined by maximum working pressure (from 5 to 40 bar).
- Type 2 hoses further categorized by grades based on reinforcing helical wires, enhancing structural integrity for demanding dredging tasks.
-
Performance and Material Requirements
- Specifies physical and mechanical properties for abrasion resistance, tear strength, ozone resistance, and temperature brittleness.
- Details hydrostatic performance, change in length under pressure, bending radius, adhesion between components, and minimum tensile strength.
- Outlines requirements for the construction of linings, reinforcement, covers, and flotation materials to ensure robustness in harsh environments.
-
Testing, Marking, and Documentation
- Prescribes type and routine testing for quality assurance, including hydrostatic, bending, vacuum resistance, and flotation recovery.
- Requirements for clear marking of hoses with type, size, pressure rating, temperature class, and manufacturing information.
- Mandates the provision of test certificates or reports upon request.
Applications
SIST EN ISO 28017:2026 is vital for sectors that rely on the safe and efficient movement of slurry and aggregate materials via rubber hoses in dredging operations. Typical applications include:
- Dredging of Harbors, Rivers, and Waterways: Ensuring the safe transit of sediment-laden water for maintenance and expansion of navigable channels.
- Land Reclamation Projects: Transferring sand and sediments from dredged areas to land reclamation sites.
- Mining and Aggregate Handling: Moving abrasive mixtures in mining, quarries, or similar industries.
- Environmental Remediation: Removing contaminated sediments from water bodies.
- Infrastructure Construction: Supporting foundation work where underwater material transport is necessary.
By adhering to SIST EN ISO 28017:2026, producers, specifiers, and users ensure hose assemblies offer proven performance, safety, and interoperability in demanding marine and industrial environments.
