Houillon Viscosity Method
The term “Houillon” refers to the specific capillary tube used to measure viscosity in ISL’s VH systems. The principle — based on straight flow approach — requires less than 1 ml of sample, speeding warm-up and analysis time. Because the specimen flows through the detection points only once, the Houillon method is ideal for both transparent and opaque samples.
Test Methods
- ASTM D7279
- ASTM D2270
