Provision of suitable means for the calibration of portable atmosphere
testing instruments
Compliance with the provision "suitable means shall be provided for the
calibration of all such instruments" in SOLAS
regulation XI-1/7, as adopted by resolution MSC.380(94), may be achieved by portable atmosphere testing
instruments being calibrated on board or ashore in accordance with the
manufacturer's instructions.
For the avoidance of any doubt, the above clarification refers to the
calibration of portable atmosphere testing instruments, as required by SOLAS
regulation XI-1/7, and not to any pre-operational accuracy
tests as recommended by the manufacturer.
