Appendix A
(Appendix to the standard)
Method for determining the vacuum degree created in the can
The vacuum degree created in the can (MPa) can be determined according to the following formula: pp+ppa
Wherein: p1 is the arithmetic mean value of the vacuum degree in the can when the canning machine continuously seals cans according to the specified production capacity, MPa, pz is the vacuum value in the vacuum chamber when sealing the can, MPa; before sealing the can, continue to evacuate the vacuum for not less than 1min, and after the vacuum degree stabilizes, measure the arithmetic mean value of the vacuum degree in the sealed can, MPa.
A2 When measuring P1 and p3, the can selected should generally be twice the number of canning stations. When measuring p1 and p3, a manual vacuum gauge for checking the vacuum degree in the can should be used, and the p2 value can be directly read from the vacuum gauge on the canning machine. 430A manual vacuum gauge should be used to check the vacuum degree in the can. The p2 value can be read directly from the vacuum gauge on the can sealing machine.A manual vacuum gauge should be used to check the vacuum degree in the can. The p2 value can be read directly from the vacuum gauge on the can sealing machine.
