    Abstract - (Show below) - (Hide below)

    Provides basic requirements for diaphragm gas meters under tender, to ensure optimum performance, both, when purchased, and after extended service; and to satisfy the requirements of statutory authorities after due consideration is given to variations in accuracies of meter testing. Covers the working environment, materials of construction and performance required of diaphragm meters of Qmax up to 8 m3/h when tested at standard conditions (MSC) on air.

    Scope - (Show below) - (Hide below)

    This Standard specifies requirements on the working environment, materials of construction and performance of diaphragm meters of maximum flow rate (Qmax) up to 8 m3/h when tested on air at pressure absorption of 125 Pa. (Meters up to this capacity are generally produced in large quantities.) The design and construction requirements are intended to provide for an expected minimum working life of twenty years.
