All the joint points (which contain gas) are covered air tight with thin sheets of polythene, for more than 8 hours. As the joints are now covered, the gas density inside them is measured by inserting a gas detecting port of a detector through these covers.

Most countries have legislation or pressure vessel codes which requires vessels to be regularly tested, for example every two years (with a visual inspection annually) for high pressure gas cylinders and every five or ten years for lower pressure ones such as used in fire extinguishers. Gas cylinders which fail are normally destroyed as part of the testing protocol to avoid the dangers inherent in them being subsequently used.
