Meets ASTM Designation: F 1080, Standard Test Method For Determining The Consistency Of Viscous Liquids Using A Consistometer. Meets MIL-R-81294B
A 75ML sample of material is poured into the reservoir and the distance of flow in a horizontal direction is read from an engraved ruled track after a fixed time following the materials release from the spring loaded gate reservoir.
