Описание (английский):

This document specifies the minimum requirements for textile-reinforced, smooth-bore rubber water-suction and discharge hoses and hose assemblies. Three types of hoses and hose assemblies are specified according to their operating duty requirements, i.e. their ambient and water temperature ranges: — ambient temperatures: −25 °C to +70 °C; — water temperatures during operation: 0 °C to +70 °C.

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.

Related standards

Key normative references and related standards cited include:

ISO 1402 (hydrostatic testing)

ISO 7233 (resistance to vacuum)

ISO 10619‑1 / ISO 10619‑2 (bending tests)

ISO 7326 (ozone resistance)

ISO 8033 (adhesion)

ISO 8330 / ISO 8331 (vocabulary and use/maintenance)

ISO 1307 (hose sizes and tolerances)

EN ISO 4641:2024 is essential when specifying or testing rubber water suction and discharge hoses to meet recognized international requirements.
