Full title and description

St ISO 4641-2024 — Rubber hoses and hose assemblies for water suction and discharge — Specification. This international standard specifies the minimum requirements for textile‑reinforced, smooth‑bore rubber water‑suction and discharge hoses and hose assemblies, including classification by duty type, basic construction and performance expectations for use in water transfer and dewatering applications.

Abstract

ISO 4641:2024 defines minimum requirements for textile‑reinforced, smooth‑bore rubber hoses and hose assemblies intended for water suction and discharge. The edition specifies three hose types classified by operating duty (ambient and water temperature ranges) and sets requirements for materials, construction, dimensions, performance (pressure/resistance), testing and marking to ensure safe, reliable operation in the stated temperature ranges.

Scope

ISO 4641:2024 applies to textile‑reinforced, smooth‑bore rubber hoses and hose assemblies used for suction and discharge of water. It covers classification into three types according to operating duty (ambient temperature and water temperature during operation), typical temperature ranges (ambient −25 °C to +70 °C; water in service 0 °C to +70 °C), basic construction and performance requirements, assembly practices and marking. The standard is intended for hoses used in industrial, municipal and mobile pumping, dewatering, drainage and general water‑handling duties.

Key topics and requirements

• Classification of hose types by duty and temperature range (three types).
• Materials and construction: requirements for inner lining, textile reinforcement and covers.
• Dimensional requirements and tolerances (inside diameter, wall/thickness tolerances, lengths).
• Performance requirements: working/proof/burst pressure guidance and suction resistance.
• Required tests and inspection: hydrostatic/proof testing, burst testing, vacuum/suction resistance, flexibility/bend tests, adhesion and ageing/ozone resistance where applicable.
• Requirements and guidance for hose assemblies, fittings and couplings used with the hoses.
• Marking, traceability, test reporting, packaging and storage instructions.

Typical use and users

Typical uses include industrial and municipal water transfer, site dewatering, construction and mining water handling, agriculture irrigation and general-purpose suction/discharge applications. Primary users are hose manufacturers, hose assembly fabricators, procurement and specification engineers, quality managers, test laboratories and end‑users specifying hoses for pumps, mobile units and fixed installations.

Related standards

Commonly referenced and related standards include ISO 1402 (hydrostatic testing of hoses and hose assemblies), ISO 7233 (resistance to vacuum), ISO 10619 (flexibility/bending tests), ISO 8033 (adhesion tests), ISO 8330 / ISO 8331 (vocabulary and marking for hoses and hose assemblies) and other ISO test-method standards used to verify performance.
