Overview
The Ford viscosity cup (Ford-5 #) is a Viscometer made according to the American Society for Testing and Materials standards ASTM D 1200, D333, D365. It is specially designed to determine the viscosity of inks, coatings, paints and other materials. It is made of high-quality aluminum and has a capacity of about 100 ml. It has a standard outflow hole at the bottom. It can be easily compared by measuring the time required for a specific volume sample to flow out.
Features
According to international standards ASTM D 1200, D333, D365 production, reliable measurement results.
2. The cup body is made of cathode aluminum oxide material, and the nozzle is made of brass material, which is sturdy and durable.
3. The design is simple, the operation is convenient, and the viscosity comparison test can be carried out quickly.
4. Capacity of about 100 ml, flow hole diameter 5.2 mm, suitable for specific viscosity range (about 215~ 1413cSt) measurement.
Principle
The Working Principle of the Ford viscosity cup is to evaluate the viscosity of a fluid based on the measurement of the time it takes for it to flow. A specific volume (approximately 100 ml) of the sample to be tested is injected into the cup, and the sample flows vertically from a standard small hole in the bottom of the cup under the action of gravity. The time required for the sample to start flowing out until the first breakpoint occurs (in seconds) is accurately recorded by the stopwatch, which represents the relative viscosity of the sample.
Applications
Inks viscosity determination, coating viscosity determination, paints viscosity determination
Standards
ASTM D1200、ASTM D333、ASTM D365
Steps
1. Thoroughly clean the cup body and flow hole with a suitable solvent before use to ensure no residue and dry it.
2. Choose the appropriate cup number according to the estimated viscosity to ensure that the outflow time is between 20 and 80 seconds.
Stir the sample evenly and filtrate, adjust the sample and flow cup temperature to (23 +/- 0.5 ° C) or the agreed temperature.
4. Adjust Ford viscosity cup holder to level (horizontal bubble centered).
5. Plug the flow hole with your finger or baffle, fill the sample with Ford viscosity cup, scrape the liquid level with a scraper, and place the receiving container.
6. Release the finger or baffle to let the sample flow vertically, and immediately start the stopwatch timing. Stop the timing when the flow appears at the first breakpoint and record the number of seconds.
7. repeability measurement three times, take the average value as the final viscosity value.
8. Immediately after the test, clean the cup with a suitable solvent to avoid using metal tools to clean the flow hole.
Notice
• During use, it should be handled with care to avoid damage or deformation of the flow hole caused by drop or collision, which will affect the Measurement accuracy.
• The cup body and flow hole must be thoroughly cleaned before and after each use to ensure that there is no residue from the last test.
• Do not use metal cleaning tools or wires when cleaning to prevent scratching the flow hole. If there is dry dirt in the flow hole, after applying solvent softening, carefully pull and clean with a soft cloth.
• The instrument is recommended to be calibrated regularly once a year to ensure measurement accuracy (users are usually not required to calibrate themselves within the first year of leaving the factory).
• Standard silicone oil should be used for calibrating and in accordance with the relevant national viscosity cup Measurement regulations.
