Overview
ISO 8330:2022 - Rubber and plastics hoses and hose assemblies - Vocabulary - is the fourth edition (2022) of the international vocabulary for the hose industry. The document standardizes terminology used for rubber, plastic and thermoplastic hoses, hose assemblies, reinforcements, fittings, and related components. It also points users to recommended terminology for electrical conductivity/resistance (see ISO 8031:2020, Annex A).
Key topics covered
ISO 8330:2022 organizes and defines terms across the whole hose lifecycle and product family. Major technical topics include:
- General definitions: hose, flexible hose, tube, tube inner lining, operating conditions.
- Types of hose: rigid, flexible, flat, spiral, corrugated, preformed, semi‑rigid, hybrid, hydraulic, OSD (oil suction/discharge) and more.
- Reinforcements and components: textile braids, metal spirals, helices, woven/knitted reinforcements, sleeves and couplings.
- Fittings and hose assemblies: hose ends, connections, assembly methods and parts of fittings.
- Geometric and dimensional terms: bore, wall thickness, bend radius, reinforcement angle and spacing.
- Mechanical properties: flexural stiffness, burst/working considerations (terminology rather than test values).
- Electrical aspects: terminology for conductivity and resistance (with guidance to ISO 8031).
- Manufacturing and testing vocabulary: production methods (mandrel-built, moulded, machine-made), common tests, deformations and defects.
- Additions and editorial updates introduced in the 2022 revision (restructured clauses, revised numbering, new/removed terms and an alphabetical index).
Practical applications and users
ISO 8330:2022 is essential for:
- Hose manufacturers and designers for consistent product specifications and technical documentation.
- Procurement and specification writers to avoid ambiguity in purchase orders and contracts.
- Testing laboratories and quality assurance teams to harmonize test reports and defect descriptions.
- Standards committees, regulators and certification bodies that reference consistent terminology.
- Maintenance and operations personnel for clear communication about components, failures and replacements.
Using a common vocabulary reduces misunderstandings in design, procurement, testing and field service, and improves interoperability across international supply chains.
Related standards
- ISO 8031:2020, Annex A - recommended terminology for electrical conductivity/resistance of rubber and plastics hoses.
- Developed by ISO/TC 45 (Elastomers) in cooperation with CEN/TC 218 - useful context for harmonized European/international practice.
