EN ISO 4641:2024 PDF

Overview

EN ISO 4641:2024 (ISO 4641:2024) specifies minimum requirements for textile‑reinforced, smooth‑bore rubber hoses and hose assemblies used for water suction and discharge. Published by CEN and aligned with ISO, this sixth edition supersedes EN ISO 4641:2016 and updates test, marking and material requirement sections. The standard covers construction, dimensions, performance testing and marking for hoses designed to operate in defined ambient and water temperature ranges.

Key topics and technical requirements

• Scope and classification
  • Applies to textile‑reinforced, smooth‑bore rubber water suction and discharge hoses.
  • Hoses are classified into three types according to operating duty (ambient and water temperature ranges).
• Temperature ranges
  • Ambient: −25 °C to +70 °C.
  • Water (in service): 0 °C to +70 °C.
• Materials and construction
  • Requirements for lining, reinforcement (textile), and cover materials and construction methods.
• Dimensions and tolerances
  • Inside diameter, enlarged ends, unit lengths, lining and cover thickness tolerances.
• Performance and physical tests
  • Hydrostatic (proof) pressure and burst tests, resistance to suction flattening, low‑temperature flexibility, adhesion between components, ozone resistance of covers, and minimum bend radius requirements.
  • Testing follows referenced ISO methods (e.g., ISO 1402 hydrostatic testing, ISO 7233 vacuum resistance, ISO 10619 bending tests).
• Couplings, fittings and assemblies
  • Guidance for compatible couplings and end fittings and requirements for hose assemblies.
• Marking, test reporting and storage
  • Marking of hoses and assemblies, test reports/certificates, packaging and storage instructions.

Applications and users

EN ISO 4641:2024 is intended for manufacturers, specifiers and end users of rubber hoses for water handling, including:

• Industrial and municipal water pumping and transfer systems
• Dewatering and drainage operations
• Construction, mining and agricultural water transfer
• OEMs specifying hose assemblies for equipment and mobile units

Quality managers, procurement teams, testing laboratories and designers use this standard to ensure safe, reliable and compliant water suction and discharge hoses.
