A
Adherence — The extent to which a coating bonds to a substrate.
Adherence Index--Measure of the Adherence of porcelain enamel and ceramic coatings to
sheet metal.
Alpha Rockwell Hardness —Index of the resistance of a plastic to surface ration by a
specified indenter under specified load applied with a Rockwell Hardness tester.
Higher values
indicate higher indentation Hardness.
Axial Strain — The Strain in the direction that the load is applied, or on the same axis as the
applied load.
Analogue board — A machine circuit board, which converts analogue signals into digital signal.
Anchor Pin — A steel pin that connects a grip or jig to an eye end
Auto Return — Auto Return,
automatically to its
Zero point at the end of the test.

bend tests apply to specific forms or types of materials. For example, materials specifications
sometimes require that a specimen be bent to a specified inside diameter (ASTM A-360, steel
products). A bend test for Ductility of welds is given in ASTM E-190. Results of tests of
fiberboard are reported by a description of the failure or photographs.
Bending Strength — Alternate term for Flexural Strength. It is monly used to describe
flexure properties of cast iron and wood products.
Bond Strength — Stress (tensile load divided by area of bond) required to rupture a bond formed
by an adhesive between two metal blocks.
Break Elongation —The Elongation of the specimen to the break point.
Breaking Load — Load which causes fracture in a tensile, compression, flexure or Torsion Test.
In tensile tests of textiles and yarns, breaking load also is called breaking strength. In tensile
tests of thin sheet materials or m
