Methods for proving the gas tightness of vacuum or pressurized plant
METHODS FOR PROVING THE GAS TI
Ten methods for application to evacuated plant, seven to pressurized plant.
Five involve direct measurement of quantities but are insensitive or lengthy. Others use search gas and detectors sensitive to such gas.
Four use vacuum gauges which may be able to serve another purpose on plant.
Each method describes apparatus, special precautions, procedure, interpretation of results, working principles, sensitivity.
Design of plant; contracts; blockage of capillary leaks; leak rates of different fluids; worked examples; safety precautions; bibliography; methods of leak location.
