As a general rule, shore-calibration is only required for |
|
|
|
|
|
|
|
|
reference equipment/instruments. |

|
a reference instrument. |

When testing the ESD a system should be in place to insure all ESD activation points are part of a rotation system such that they are all tested as part of the testing regime with-in 12 months. Valves must close smoothly in the required time period as stated in the IGC Code (less than 30 seconds after ESD activation), but allowing sufficient time to avoid surge pressure if activated during cargo transfer.
