This document specifies the requirements for three types, three classes and two categories of textile-reinforced rubber hose for compressed air, up to a maximum working pressure of 2,5 MPa (25 bar) with an operating-temperature range of −40 °C to +70 °C, depending on the type and category.

Abstract

Overview

EN ISO 2398:2024 - Rubber hoses, textile-reinforced, for compressed air - Specification (ISO 2398:2024) is a CEN-endorsed European adoption of the ISO standard defining requirements for textile-reinforced rubber hoses used with compressed air. It covers hoses up to a maximum working pressure of 2.5 MPa (25 bar) and operating temperatures from −40 °C to +70 °C depending on type and category. This edition supersedes EN ISO 2398:2016 and aligns with ISO/TC 45 and CEN/TC 218 work.

Key topics and requirements

Classification
- Types by pressure rating: Type 1 (1.0 MPa / 10 bar), Type 2 (1.6 MPa / 16 bar), Type 3 (2.5 MPa / 25 bar).
- Classes by oil resistance: Class A (non-oil-resistant), B (normal oil resistance), C (good oil resistance).
- Categories by temperature range: N-T (−25 °C to +70 °C), L-T (−40 °C to +70 °C).
Materials & construction
- Hose construction: rubber lining, textile reinforcement (natural or synthetic), rubber cover.
- Lining and cover must be uniform, concentric and free from defects; cover may be smooth or fabric-marked.
Dimensions & tolerances
- Inside diameters and tolerances specified for hose sizes from 4 mm to 102 mm (see Table 1).
- Concentricity tolerance: ≤ 1.0 mm for inside diameters up to 76 mm; ≤ 1.5 mm for larger sizes.
- Length tolerances follow ISO 1307.
Minimum thickness
- Type 1: lining 1.0 mm / cover 1.5 mm
- Type 2: lining 1.5 mm / cover 2.0 mm
- Type 3: lining 2.0 mm / cover 2.5 mm
Physical properties
- Rubber compound requirements (lining and cover): minimum tensile strength 7.0 MPa, minimum elongation 250% (ISO 37).
- Ageing limits and liquid-resistance limits are specified (ageing: change in tensile ±25%, change in elongation ±50%; liquid resistance per ISO 1817 vary by class).
Testing, marking & documentation
- Normative type and routine tests defined (Annex A); testing frequency, test reports/certificates and marking requirements are included.

Applications and users

Typical applications: pneumatic tools, workshops, compressed-air distribution, construction, automotive maintenance and industrial pneumatic systems operating up to 25 bar.
Primary users: hose manufacturers, OEMs, quality and compliance engineers, procurement/specification teams, testing laboratories, and safety officers.

Related standards

Normative references include ISO 37, ISO 188, ISO 1307, ISO 1402, ISO 1817, ISO 4671, ISO 7326, ISO 8330, ISO 8033, ISO 10619-1/2 - all relevant for testing, dimensions, terminology and performance verification.

Keywords: EN ISO 2398:2024, rubber hoses, textile-reinforced, compressed air, hose specification, working pressure, hose testing, concentricity, tensile strength, oil resistance.
