The Pressure Systems Safety Regulations 2000 (PSSR) require pressure systems to be inspected in accordance with a Written Scheme of Examination.
The regulations apply to owners and users of relevant fluids including steam, gases under pressure and any fluid kept artificially under pressure and which becomes a gas when released to the atmosphere.
There is a legal requirement for thorough examination of pressure vessels and receivers that contain steam, compressed air and refrigerants. Any pressure vessel containing compressed gas over 250 bar / litres capacity requires inspection.
To establish whether a vessel requires inspections multiply the vessel operating pressure (in bar units) by the vessel capacity (in Litres) i.e. 10 bar x 50 Litres = 500 bar / litres Capacity and therefore is above the 250 bar / litre threshold and requires an inspection with a written scheme of examination.
Owner / users of refrigeration plant containing pressure vessels, with compressor power over 25 kilowatts also require a written scheme of examination and inspection.
SIS can provide you with full compliance, by means of thorough examination together with Written Scheme of Examination documentation.
