What is ISO 23826 about?
ISO 23826 focuses on gas cylinders and covers the function of a ball valve. A gas cylinder is a pressure vessel for the storage and containment of gases at above atmospheric pressure. ISO 23826 specifies design, type testing, marking, manufacturing tests and examinations requirements for valves used as follows, which convey compressed gases, liquefied gases and dissolved gases:
- Closures of refillable transportable gas cylinders, pressure drums and tubes
- Main valves for cylinder bundles
- Valves for cargo transport units [trailers, battery vehicles, multi-element gas containers]
Ball valves conforming to ISO 23826 can be expected to perform satisfactorily under normal service conditions. Pressure values given in ISO 23826 are given as gauge pressure (pressure exceeding atmospheric pressure).
ISO 23826 pays particular attention to:
- Safety (mechanical strength, impact strength, endurance, leak tightness, resistance to acetylene decomposition)
- Suitability of materials
- Testing
- Marking
Who is ISO 23826 for?
ISO 23826 on gas cylinders is useful for:
- Manufacturers and suppliers of gas cylinders and ball valves
- Powering industrial ovens sectors
- Inspection bodies that include inspection of gas cylinders in their service
- Quality control personnel
- Design engineer
Why should you use ISO 23826?
Gas cylinders ball valves are designed to withstand mechanical impact without needing additional protection, they need to comply with the highest quality standards and regulations. ISO 23826 provides you with design requirements for ball valves that ensure the correct functioning and fitting of the valve and checks for other defects in the ball valve prior to dispatch on storage. Following design guidelines given in ISO 23826 helps you to manufacture high-quality ball valves and ensure that these valves will be safe for use.
ISO 23826 states tests and examinations performed to demonstrate conformity to this document is conducted using instruments calibrated before being put into service and thereafter according to an established programme.
ISO 23826 provides you with test procedures and test requirements for testing of gas cylinder ball valves including operation test, excess flow valve test, leak tightness test, endurance test, hydraulic pressure test.
