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.
