Overview
ISO 10286:2025 - Gas cylinders - Vocabulary provides a standardized set of terms and definitions for the manufacture, use, transport and inspection of gas cylinders and other pressure receptacles and their fittings. The sixth edition consolidates terminology across metal and composite cylinders, tubes, pressure drums, bundles, MEGCs, closed cryogenic receptacles, metal‑hydride storage systems and associated accessories. It aligns many entries with the UN Model Regulations and includes French and German equivalents (Annex B) and illustrative figures (Annex C).
Key Topics (what the standard defines)
- Scope and structure: Clause 3 organizes terms into topics such as pressure receptacles, accessories, manufacture, testing and inspection, characteristics/pressures and materials.
- Pressure receptacle types: Definitions for cylinder, tube, pressure drum, bundle of cylinders, salvage pressure receptacle, tank, MEGC and battery‑vehicle.
- Composite classifications: Type 1–5 categories (metal and composite cylinder types, liner/load‑sharing distinctions).
- Specialized receptacles: Closed cryogenic receptacles, metal hydride storage systems, acetylene cylinders, aerosol dispensers and small gas cartridges (with water‑capacity thresholds where provided).
- Manufacture/test/inspection vocabulary: Terms such as minimum design wall thickness, external coating, pressure receptacle shell, and precautionary label.
- Normative positioning: No normative references in the document; references to related ISO guidance (e.g., ISO 10241‑1 terminology presentation) and UN Model Regulations are used.
Practical applications and who uses it
ISO 10286:2025 is essential for anyone working with gas cylinders and pressure receptacles who needs clear, harmonized terminology:
- Manufacturers and designers - to ensure consistent product specifications and documentation.
- Standards developers and regulatory bodies - to align national and international rules (ADR, RID, ADN, UN Model Regulations).
- Inspection and testing laboratories - to standardize reporting, test descriptions and acceptance criteria terminology.
- Transport and logistics operators - for correct classification, labeling and communication of hazards.
- Safety managers, maintenance personnel and trainers - to improve training materials, operating procedures and incident reporting.
- Translators and technical authors - benefits from the bilingual/multilingual equivalents in Annex B for accurate documentation.
Related standards and references
- UN Model Regulations (for transport/terminology alignment)
- ISO/TC 58 (Gas cylinders) and linked technical committees (ISO/TC 220, ISO/TC 197)
- ISO 10241‑1 (terminology presentation) and referenced ISO documents (e.g., ISO 7225, ISO 80000‑4) for contextual use
Using ISO 10286:2025 ensures consistent gas cylinder terminology, reduces ambiguity in design, testing and transport documentation, and supports regulatory compliance across international supply chains.
