If the cylinder passes all the previous inspections it is ready to be hydrostatically tested, when it is filled with water and connected to the test panel. The cylinder is pressurised to fill pressure twice to check accuracy of the panel and remove air bubbles from the system.
The cylinder is then pressurised to its test pressure and held there for one minute. The pressure is slowly released and the expansion measured on a manometer tube. The maximum allowed expansion is the water capacity of the cylinder in kilograms divided by five. The cylinder is disconnected from the test panel and inverted to drain after which it is dried using warm air. After a final internal inspection to ensure proper drying the neck “o”ring is replaced and the valve installed.
The cylinder is then stamped, filled, leak tested at the neck and the test certificate completed. Failed cylinders are destroyed in accordance with the standard.
Scuba Cylinders are high pressure vessels and as such should be handled carefully. They should be washed after use and the valves serviced every twelve months the same as your other valuable gear. In Sweden all scuba cylinders are required to be hydrostatically tested every 5 years. This is carried out in accordance with MSBF 2016:8 Standard 2016 by a Certified Test Station. The cylinder is then stamped around the neck area indicating the month and year it was tested along with the test station number.
