Tbs following instruments are checked «t least once per year.
Examination equipment supplied by outside firns is checked before
their use in the KKC.
Examination instruments :
Check on the basis of
Yoke magnets :
KKG-Q-PSO22 and DIN 5U31/T2 for
adequate magnetic induction
Bloch light lamps
Determination of maximum permissible
distance for light Intensity
i 8W/m using * Bloch light-meter.
the Bloch light-meter is checked once
per year by the supplier.
Tangential field strength
With reference to the permanent
magnetic calibration Bloch (before every measurement).
For the other magnetization instruments, the adequacy of
magnetization must be demonstrated on the examination area with the
magnetic field Indicator.
The results of instrument checks are entered as HT-records.
