Overview

EN ISO 4671:2022 (ISO 4671:2022) specifies standardized methods of measurement for rubber and plastics hoses and hose assemblies. Published by CEN/ISO, this fourth-edition standard defines how to measure internal and external dimensions, wall and lining/cover thicknesses, concentricity, assembly lengths, and how to verify the through‑bore of hydraulic hose assemblies. The document also covers test piece conditioning and the temperature at which measurements shall be taken. EN ISO 4671:2022 replaces the 2007 edition and incorporates amendment A1:2011.

Key topics and requirements

Measurement scope: inside diameter, outside diameter (including diameter over reinforcement for hydraulic hoses), wall thickness, concentricity, lining and cover thickness.

Multiple measurement methods: the standard provides several numbered methods (e.g., Method 1…Method 7 for inside diameter; several methods for outside diameter and wall thickness) so laboratories and manufacturers can select the appropriate technique for hose type and construction.

Length and identification: specifies methods to measure and mark the lengths of hoses and hose assemblies and defines measurement points for both loose hoses and fitted assemblies.

Through-bore verification: includes a procedure to verify the continuity/through‑bore of hydraulic hose assemblies (important for flow and safety checks).

Test conditioning and temperature: requires conditioning of test pieces and prescribes measurement temperatures to ensure reproducible, accurate dimensional results.

Mandatory language: permissions in prior editions have been elevated to requirements (uses “shall”), reflecting stricter conformity expectations.

Traceability and reporting: defines essential elements for the test report so measurements are repeatable and auditable.

Practical applications

Quality control and production inspection for hose manufacturers (dimension checks during manufacturing and final inspection).

Incoming and outgoing acceptance testing for suppliers and purchasers to confirm conformance with specified diameters, wall thickness, concentricity and lengths.

Laboratory test procedures for certification bodies and independent test labs.

Design validation and R&D when developing new hose constructions (ensuring internal/external dimensions meet design intent).

Maintenance and safety checks on hydraulic hose assemblies where through-bore verification and diameter over reinforcement are critical for system performance.

Related standards and context

EN ISO 4671:2022 was prepared by ISO/TC 45 (Rubber and rubber products) in collaboration with CEN/TC 218 (Rubber and plastics hoses and hose assemblies). It supersedes EN ISO 4671:2007 and its amendment EN ISO 4671:2007/A1:2011.

Keywords: EN ISO 4671:2022, ISO 4671:2022, rubber and plastics hoses, hose assemblies, measurement methods, inside diameter, outside diameter, wall thickness, concentricity, lining thickness, cover thickness, hose length, through-bore verification.
