Tensile Strength:Ultimate strength of a material subjected to tensile loading. It is the maximum stress developed in a material during a tensile test.

Tension: A force tending to stretch or elongate a sample or material.

Test Definition: Outlines the test methods including calculations, variables etc.

Test Height: The distance from the base of the sample to the top of the sample.

Test Type: Examples of test types include Tension, Compression, Burst, Peel, 3 Point Flexural, Paper, Seam, Yarn Tear and Friction.

Thickness: The dimension between two surfaces of an object, usually the dimension of smallest measure.

Thickness Gauges: An instrument for measuring the specimen thickness.

Turns: The number of turns about its axis per unit of length of a yarn or other textile strand. Twist may be expressed as turns per inch (tpi), turns per metre (tpm), or turns per centimetre (tpcm).

U

USB: Universal Serial Bus. An interface available on modern PCs.

V

Variables: User defined variables that can be used to collect extra information from the user that is not directly generated by the tester.

Y

Yield Point: The point at which the strain increases without the associated increase in stress. Only a few materials (eg steel) have a yield point and generally only under tensile forces.
