The ministerial decree of 15th March 2000 stipulates the frequency of inspections and reclassifications for hydro-pneumatic accumulators with PS.V exceeding 200 bar.l and maximum service pressure exceeding 4 bar. These inspections and reclassifications must be carried out at the operator's request. Appliances and accessories must always be in a good condition. The owner must clean, repair and make necessary replacements in due time.



INSPECTION consists in an internal and external tour of the equipment once all removable parts have been exposed and a verification of safety accessories as often as necessary depending on deterioration risks. The thickness of the sheet metal must be measured to determine feasibility of the reclassification. For hydro-pneumatic accumulators, inspections must be carried out at least every 40 months. NB: For installations abroad, regulations depend on the country of installation. Refer to the regulations in force in the country concerned.

RECLASSIFICATION consists in an internal and external inspection and a hydraulic test of the equipment at its test pressure, and a verification of safety accessories, with re-calibration or replacement, and verification of the existence and accuracy of documents associated with the pressure equipment. Reclassification of pressure equipment (hydro-pneumatic accumulators) is compulsory every 10 years. It is validated by an approved body.
