==Terminology==

In [[Polymer Testing|polymer testing]], a conventional hardness test method (see: [[Hardness|hardness]]) refers to all methods in which characteristic [[Material Value|values]] are determined using device systems that do not have any [[Electronic Instrumentation|instrumentation]], i.e., it is not technically possible to electronically record the force and deformation behaviour (penetration depth, deflection, elongation) during the [[Stress|loading]] of a test [[Specimen|specimen]]. For this reason, these hardness testing methods usually only output one characteristic value, which may be corrected by the yield value (see: [[Tensile Test Compliance|tensile test compliance]]) of the test system.

==Conventional hardness testing methods==

The following conventional hardness testing methods for [[Polymer Testing|polymer testing]] are described in more detail in this [[Lexicon Polymer Testing & Diagnostics|online lexicon]]:

* [[Barcol Hardness|Barcol hardness]]
* [[BUCHHOLZ Hardness|BUCHHOLZ hardness]]
* [[IRHD Hardness|IRHD hardness]]
* [[KNOOP Hardness|KNOOP hardness]]
* [[Ball Indentation Hardness|Ball indentation hardness]]
* [[ROCKWELL Hardness|ROCKWELL hardness]]
* [[SHORE Hardness|SHORE hardness]]
* [[Vickers Hardness|Vickers hardness]]

If the test load and penetration depth are recorded continuously and simultaneously during the test, this is referred to as [[Instrumented Hardness Testing – Method & Material Parameters|instrumented hardness testing]] or recording hardness testing.
