Kink test. Method for determining ductility of metal wire. A short section of wire is looped and drawn in tension to produce a kink. Relative ductility is indicated by the occurrence or non-occurrence of failure and extent to which kink may be opened up without failure.

 

Knoop hardness number. Measure of indentation hardness of a material (especially an organic coating) measured with a pyramidical diamond indentor of prescribed dimensions. (ASTM D-1474).

 

Knot strength. Tenacity of a fiber in which an overhand knot is tied. Knot strength is a measure of a fiber’s sensitivity to compressive and shear stresses.
