TR 1010/2 Tu-4 cups are equipped with a copper cup and a stand, suitable for laboratory viscosity testing, with a capacity of 100±1ml.
Tu-4 cup is designed in accordance with GB/T 1723 standard. It is usually suitable for viscosity measurement of products with an outflow time of less than 150 seconds. The time for a certain amount of sample and a certain temperature to flow out of a hole with a specified aperture is in seconds. (s) said.
The obtained sample outflow time t (s)
Use the following formula to convert to kinematic viscosity value (mm2/s):
When t<23s, t=0.154μ+11
When 23s≤t≤150s, t=0.223μ+6.0
