Overview
EN ISO 6224:2024 (adopted by CEN as EN ISO 6224:2024) is the international specification for textile‑reinforced thermoplastics hoses intended for general‑purpose water‑discharge applications. The fifth edition (ISO 6224:2024) updates the 2011 edition and sets requirements for materials, construction, dimensions, physical properties, testing, marking, packaging and storage for non‑potable, non‑firefighting water hoses.
Key topics and technical requirements
- Scope & exclusions: Applies to general‑purpose water discharge hoses only; explicitly not intended for potable (drinking) water, washing‑machine inlets, firefighting hoses, special agricultural machines or consumer gardening hoses.
- Materials & construction: Hoses must consist of a flexible thermoplastic lining, a textile reinforcement (natural or synthetic) and a flexible thermoplastic cover. Linings and covers must be uniform, concentric, fully gelled and free from visible defects.
- Classification / Pressure ratings: Hoses are classified into three types by maximum working pressure:
- Type 1 (Low pressure) - 0.6 MPa (6 bar) at 23 °C; 0.36 MPa (3.6 bar) at 60 °C
- Type 2 (Medium pressure) - 1.0 MPa (10 bar) at 23 °C; 0.65 MPa (6.5 bar) at 60 °C
- Type 3 (High pressure) - 2.5 MPa (25 bar) at 23 °C; 1.6 MPa (16 bar) at 60 °C
- Dimensions & tolerances: Inside diameters, tolerances, minimum wall thicknesses and length tolerances are specified (see Table 1 and ISO 1307/ISO 4671 references). Concentricity tolerance between inside diameter and outside cover surface is maximum 1.0 mm.
- Testing & conformity: Standard defines type, routine and production tests, with Annex A normative (type and routine testing) and Annex B informative (recommended production tests). Requirements for test certificates/reports and marking are included.
- Quality aspects: Includes physical property requirements for thermoplastic materials and finished hoses and references standard test methods for ageing, flexibility, hydrostatic testing and dimensional measurement.
Applications and users
- Typical users: hose manufacturers, component suppliers, OEMs, procurement/specification engineers, testing laboratories, and quality/standards professionals.
- Typical applications: industrial water transfer, irrigation systems (non‑consumer), construction site water discharge, cooling water lines and similar general‑purpose water conveyance where potable or firefighting certification is not required.
