Appendix B
Glossary
The following glossary of terms related to mechanical
tests of materials will assist you in the application of
your testing system. As materials are commonly speci-
fied by their properties, defining a property and measur-
ing it is generally done by a mechanical testing
procedure. The procedures cited here refer to American
Society for Testing and Materials (ASTM) standards and
test methods. Most of these standards have an equivalent
DIN or ISO standard.
Understanding these tests and their applications is basic
to performing them. The terms listed in this glossary are
chosen because of their relation to the types of tests
within the capability of a Series 4400 testing instrument.
Bend Test.
Method for measuring ductility of certain materials.
There are no standardized terms for reporting bend test
results for broad classes of materials; rather, terms asso-
ciated with bend tests apply to specific forms or types of
materials. For example, materials specifications some-
times require that a specimen be bent to a specified in-
side diameter (ASTM A-360, steel products). A bend
test for ductility of welds is given in ASTM E-190. Re-
sults of tests of fiberboard are reported by a description
of the failure or photographs (ASTM D-1037).
