3 Terms and definitions

The terms and definitions defined by IEC 61196-1 and the following apply to this document.

3.1

Gauge gaugelength

Used to measure the mark length of the extended test section.

3.1.1

Original gauge length originalgaugelength

Lo

The gauge length before applying force.

3.1.2

Gauge gaugelengthatfracture at break

Lt

The gauge length at which the specimen breaks.

3.2

Tensilestrength tensile strength

Rm
