Ford Flow Cup Ford Viscosity Cup Number 1#2#3#4#5#6# with Cup Stand Bracket 

I. Introduction

Ford cup according to the paint and raw materials standards ASTM D 1200, D333, D365 in the provisions of the production, used to determine the viscosity of inks, paints, lacquers and other viscosity more convenient viscometer. It is made of high quality aluminium cup with a small hole at the bottom and a capacity of about 100ml.

Ford cup through the determination of aluminium cup in a certain capacity of the test material from the bottom of the small hole in the time required to flow out to measure the viscosity of the test material.

II. Technical parameters

1. Cup volume：100±1ml

2. Various cup indicators

Cup number	Hole diameter	Measuring range	Outflow time
1#	2.10 mm	10-35 cSt	25-105 sec
2#	2.80 mm	25-120 cSt	25-105 sec
3#	3.40 mm	49-220 cSt	25-105 sec
4#	4.10 mm	70-370 cSt	20-105 sec
5#	5.20 mm	200-1200 cSt	20-105 sec
6#	6.00mm	200-1300cSt	20-105 sec

III. Use method: 

1. should be selected before the use of suitable solvents to wipe the inner wall of the cup (Note: Please pay special attention to the cleaning of the cup body small holes, can be twisted into a rope of soft paper, in the outflow holes in the repeated pull); and then dry in the air or with a cold wind blowing dry, do not allow the past measurement of the liquid residue adhering to the liquid in the cup or flow outlet.

2. choose the appropriate cup number, in order to control the outflow time between 20 ~ 80 seconds (see technical parameters)

3. the test solution is stirred and filtered in not less than 567 holes / cm2 of the sieve, and make the sample and outflow cup temperature adjustment to (23 ± 0.5 ℃) or another agreed temperature

4. Adjust the Ford Cup holder so that the top horizontal bubble is centred.

5. the sample will be injected into the Ford Cup, at the same time with a finger to block the outflow hole (if corrosive liquids can be used to block the outflow hole baffle), filled with a metal or glass plate in the cup scraping, excess sample scraped into the viscosity cup edge grooves, placed to take over the cup.

6. will release the finger or push away from the baffle, the specimen flow out vertically, and at the same time open the stopwatch. When the first breakpoint to stop the clock, the seconds of outflow time is the viscosity value of the sample to be measured.

7. repeat the measurement three times, take the average value for the final reading.

8. immediately with a suitable solvent for its cleaning. Never use metal cleaning tools or wire. If the flow out of the hole is stained by dry sediment, should be suitable solvents to make it soft, and then carefully cleaned, such as with a soft cloth through the flow out of the hole to pull the cleaning.

IV. Maintenance Precautions

Because of the Ford Cup fall, collision will make the small hole part of the damage or deformation, measurement error, in use to be very care.

 

V. Calibration 

1.the instrument should be used every year after regular calibration (factory nozzle diameter in the factory with traceable to the NIST oil Newtonian oil has been calibrated, the user in the purchase of a year after the user does not need to be calibrated)

2. calibration needs to use standard silicone oil in accordance with the relevant national viscosity cup measurement procedures.

VI. Other

The results obtained for a particular immersion cup are expressed in ‘seconds’ at a specified temperature. To convert ‘seconds’ to centistokes, refer to ASTM D 4212.
