Ten-yearly: complete all shorter-interval activities; test every nozzle for free and unobstructed flow with a continuous flow of nitrogen or a suitable alternative; hydrostatically test transportable gas cylinders more than 10 years past their last test to AS 2030.1 (first test due 10 years after first fill or, if unknown, cylinder manufacture); and internally inspect engineered pressure vessels such as low pressure carbon dioxide tanks to AS/NZS 3788 (first inspection due 10 years after manufacture).
The graph holds this control, the 0 it maps to, and the evidence behind each claim, over MCP and REST.
