There are significant differences among countries in regulating the supply and operation of boilers and pressure vessels. These differences include compliance with specific standard s limiting source or specification of materials, use of specific inspection bodies and discriminatory certification systems or import licenses. However, these standards have a proven history of supporting public safety and good commercial operating experience. BS ISO specifies performance requirements for boilers and pressure vessels, to ensure the integrity of the pressure boundary. An important safety requirement is the suitable provision of technical requirements taking into account the various modes of failure that can occur in boilers and pressure vessels.

ISO defines the performance requirements for the construction of boilers and pressure vessels. It is not the intent of ISO to address operation, maintenance and in-service inspection of boilers and pressure vessels. In relation to the geometry of the pressure-containing parts for pressure vessels, ISO includes welding end connection for the first circumferential joint for welded connections, first threaded joint for screwed connections, face of the first flange for bolted, flanged connections, first sealing surface for proprietary connections or fittings and safety accessories, where necessary.
In relation to the geometry of pressure-containing parts for boilers, ISO covers feedwater inlet including the inlet valve to steam outlet including the outlet valve , including all inter-connecting tubing that can be exposed to a risk of overheating and cannot be isolated from the main system, associated safety accessories and connections to the boilers involved in services such as draining, venting, desuperheating, etc.
ISO does not apply for nuclear components, railway and marine boilers, gas cylinders or piping systems or mechanical equipment, e. Check out our FAQs. Buy this standard. Therefore this version remains current. CHF 88 Buy. Life cycle A standard is reviewed every 5 years 00 Preliminary.
