GARDCO STANDARD FORD VISCOSITY CUPS
VISCOSITY MEASUREMENT BY
A SERIES OF SIX GARDCO STANDARD FORD CUPS
IMPORTANT FEATURES
MEETS AND EXCEEDS ASTM D 1200
·       +/-2% Production Tolerance
·       Close production tolerance permits replacement and interchange of orifices without loss of acceptable accuracy.
·       Save a considerable sum. Purchase only one cup with all six orifices instead of six complete cups.
·       New precision “Snap-In” “Snap-Out” orifices make it easy to change cup orifice size.
·       All Gardco Ford cups are alodine finished machined aluminum with removable brass orifice.
·       Six orifice sizes: No. 0, 1, 2, 3, 4, 5.
·       Series range extends from 2 to 1413 centistokes.
·       New seconds to centistokes conversion table furnished with every cup.
·       Calibration traceable to the U.S. National Institute of Standards and Technology.
·       Qualifies under ANSI/NCSL Z540-1 or ISO/IEC 17025:2005, ISO 9001:2008 as applicable. Conforms to ISO 9000 when ordered with calibration certification.
·       Cup No. 5 compatible to requirements of Federal specification MMM-A-121 for Adhesives.
Additional Features
·       The flow formula for each cup in the series has been selected to provide results which are as close as possible to an
average of other similar Ford Cups.
·        The flow formula as applied to the physical dimensions of each cup in the series has been confirmed with the use of
standard oils traceable to National Institute of Standards and Technology and other liquids from essentially zero viscosity
to a viscosity proportional to 150 seconds flow time.
·        Cup dimensions influencing flow time conform to those specified in ASTM D-1200 except for very minor adjustment of
orifice diameter.
·       Weight of the cup has been reduced by 20% to minimize influence of cup temperature on the temperature of the
material being measured.
·       The top interior of the orifice has been shaped to provide a sharper break in the stream as the cup empties. This design
also provides for a better definable orifice length with respect to theory.
·       The taper fit of the orifice eliminates hard to clean areas.
·       The orifice is readily removable with furnished wood dowel and inserted without the use of tools.
·       The design of the bottom of the cup gives increased protection to the orifice.
·       The drip ring has been deepened to accommodate a greater amount of material.
·       A specially designed tripod support is available to enhance the use of the cup.
Care of Cup
The GARDCO viscosity cups are precision instruments. To maintain them in their initial condition and calibration, they should
be cleaned following each use with a suitable solvent and a soft brush or lint-free cloth, Particular care should be used in
cleaning the orifice to avoid leaving deposits or scratches on the internal surfaces. Nylon fishing line has been found to be
suitable. It is good practice to retain a pint of standard calibration oil which can be used to periodically insure that the
cup maintains initial calibration.
