To support those involved in the pressure testing of equipment and systems, EEMUA has issued a new edition of its key publication EEMUA 168 “Guide to pressure testing of equipment”, released an awareness level e-learning module on pressure testing, and made available a new data store for sharing lessons learned from pressure testing related incidents.
Pressure testing of equipment after manufacture, assembly, and when in-service, whether by hydrostatic or pneumatic means, presents hazards from stored energy and if the failure occurs may result in significant harm to people. There continue to be injuries and fatalities due to poor pressure testing practices. Root causes frequently include poor planning, lack of competence, and failure to properly risk assess or follow the rules. Many of these accidents could have been prevented had adequate training and risk management processes been in place.
EEMUA 168 (Edition 3), ‘Guide to pressure testing of equipment, guides on if, when and how pressure testing can be carried out on pressure equipment and systems, based on risk assessment and a safe system of work. Significantly, the new edition introduces a competency framework for pressure testing personnel.
The guidance applies to the lifecycle of pressure equipment and systems, from the manufacturer, and throughout their operating lifetime. It applies to all types of non-transportable industrial pressure equipment and systems, including pressure vessels and pipework. Some alternatives to pressure testing are also considered, and when it may be appropriate to employ them.
