Standard gas cylinder

A standard gas cylinder is a pressure vessel that stores a mixture of gases of known composition. It is used to calibrate single and multi gas detector / analyzers. The details of a standard gas cylinder and its components are stored in a Standard Gas Cylinder record and Standard Gas Component records, respectively. You must create these records before you calibrate single or multi gas detector / analyzers. Note that for each component in the cylinder, you must create one Standard Gas Component. A Standard Gas Cylinder is linked to each Standard Gas Component through the Has Component relationship.
