Brytindex

Brytindex, literally "breaking index" in Swedish, is a term used in several Scandinavian technical domains to describe a measure related to a material's resistance to fracture or failure. There is no universal definition or international standard for brytindex; its exact meaning depends on the field and the organization that uses it.

In materials science and engineering, brytindex is often understood as a comparative indicator of brittleness or fracture propensity. It may be derived from mechanical testing, such as the stress at fracture, the energy absorbed in fracture, or a composite score combining multiple properties. The index may be dimensionless or expressed with units, and its interpretation requires knowledge of the test method and reference material used for normalization.

In papermaking and textile industries, brytindex is sometimes used to describe the breaking or tear strength of a sheet or fiber. Tests may measure the force required to initiate a break, with the result reported as a numeric index that allows comparison between grades or batches.

In mining or rock engineering contexts, brytindex can denote a breaking index for rock, indicating how readily rock can be broken by mechanical cutting or blasting. Such use is common in internal standards and should not be confused with general rock strength ratings.

Because there is no single universal definition, users should refer to the specific standard or method used by the issuer of a brytindex value to understand its meaning, scale, and relevance.
