K-Mass
An epoxy-based intumescent coating to provide fire protection. Works by endothermic reaction rather than insulation.
Key Stop
A method of restricting the travel of a ball valve from fully open to fully closed and vice versa. The stem key bears against the ends of an arc machined in or attached to the adaptor plate.
Knoop Hardness
The relative micro-hardness of a material is determined by the Knoop indentation test. In this test, a pyramid-shaped diamond indenter (called a Knoop indenter) is pressed against a material making a rhomboidal impression with one diagonal seven times longer than the other. The hardness of the material is determined by the depth to which the Knoop indenter penetrates.
