11. Calibration of the Falling Ball Viscometer

The falling ball viscometer is checked according to the
HAAKE regulations before delivery. The geometry relates
strictly on the DIN 53015/ISO 12058 and therefore the listed
ball constants can be used.
The calibration of the instrument can be done using nation-
ally recyclable calibration fluids. This procedure is also rec-
ommended for new balls or after repairs and for falling ball
viscometers integrated into a measuring procedure accord-
ing to ISO 9000.
Testing ...
to be defined by the user or to be read in the QC-hand book.
Calibration fluids acknowledged in the corresponding user
country, e.g. Europe: DKD/PTB calibration fluids, in Japan:
JIS fluids or in the USA: Cannon calibration fluids.
The calibration excludes the influence of allowed tolerances
when measuring balls and falling tubes.
The following Thermo Fisher Scientific products can be used
for testing the instrument:
