Under the Pressure Systems Safety Regulations 2000 (PSSR) the user/owner is responsible to ensure there is a written scheme of examination in place before your expansion vessel is in operation. This applies to any system with a vessel that has a pressure X volume greater than 250 bar litres, contains a relevant fluid and operates above 0.5 bar should have a written scheme of examination in place. You should also periodically undertake expansion vessel examination by a competent person to ensure you remain compliant.
Users/owners of pressure vessels are required to demonstrate that they know the safe operating limits of their system, and that the system is safe under those conditions. Expansion vessel testing to meet PSSR 2000 will generally include external examination every 24 months and an internal examination at 60 months.
It is also worth noting that compliance to pressure testing regulations will not be met by your annual service, this is a separate inspection and all written schemes need to be undertaken by an IEng or CEng qualified engineer.
Below is an example of where expansion vessels are utilised:
- Heating systems
- Hot water systems
- Fire protection
- Refrigeration & air conditioning
