METHOD FOR CONTROLLING PRESSURIZATION OF CORKED PRODUCTS Russian patent published in 2005 - IPC

FIELD: testing equipment.

SUBSTANCE: method includes placing product into hermetic chamber, forming a pressure change on product walls, and pressurization is evaluated by comparing pressure in chamber to control pressure, which matches previously measured pressure in same chamber with hermetic standard product, identical to controlled one, while pressure change in chamber with hermetic standard product and controlled product is formed by changing gas amount therein for one and same value, and pressure in chamber is measured in same time after forming pressure change, if pressure in chamber matches control pressure. Pressurization is evaluated on basis of change of pressure in certain time duration, and as standard product a product with minimal volume is selected, maximally close to allowed limit for control product.

EFFECT: higher trustworthiness.
