About Vacuum leak test

Dear all,

As per guidelines it is saying that tha leak test is acceptable upto 0.013 BAR, if i am using -600 bar for vacuum leak test. For that what is the acceptable leak rate.

In this case same acceptance criteria will be followed as defined in HTM 2010 .i.e leakage should not be more than 0.013 bar/10minute.

As per EN285, vacuum requirement is mentioned that 70kPA (700mbar) or below. for this the rate of pressure rise shall be not greater than 1,3 mbar/min (0.13 kPa/min). This is supporting by PDA (refer PDA technical report 01). for mentioned 600 mbar vacuum same acceptance criteria is applicable.
