There are many different types of test which can be undertaken using a Tinius Olsen Testing Machine, these include Burst or Puncture,  Chewiness, Compression, Double Shear, Flexural, Folding Endurance, Friction, Hardness, Impact, Peel, Removal strength, Ring crush, Rupture, Sharpness, Shear, Slippage, Spreadability, Stickiness, Stiffness, Tear, Tensile, Texture, Torsion, Tuft Removal, Wet Strength, Heat Distortion, Vicat/ Penetration, Melt Flow, and many more.

Some of the more obvious tests are;

Puncture (Burst, Sharpness)

What is a Puncture test?

Simply stated, a puncture test determines the resistance of film to the penetration of a probe at a single constant test speed and tries to emulate what happens in the end use applications of the film.  Puncture strength tests are used to determine the puncture or rupture characteristics of a material and is typically a compressive type test where the specimen compressed by a probe until it ruptures, or until a defined travel limit is reached.

Puncture testing is commonly used to determine the strength of film, rubber or membrane, but is also by food processors to determine the ripeness of a product. Puncture testing may be used in medical applications for determining the sharpness of a hypodermic syringe or a scalpel blade etc.

Compression

What is a Compression test?

Simply put, a compression test allows you to see how a material behaves when subjected to a crushing, or compressive, load. The specimen is subjected to an increasing compression load and the deformation of the specimen is recorded.  Compressive stress and strain are calculated and recorded as a stress-strain curve which is then used to determine elastic limit, proportional limit, yield point, yield strength and ultimate compressive strength. 

Tensile 

What is a tensile test?

A tensile test is a test where a clamped specimen is subjected to a constant rate of tensile loading such that it stretches and ultimately breaks. Typically these tests are performed in accordance with an internationally recognised standard procedure and calculation of results so that the data is portable between labs. The rate of loading can be applied as either a constant rate of extension, constant rate of strain or constant rate of load, depending on the standard.

 Flexure

What is a flexure test? 

A flexure test, also called a transverse test, simply measures the bending behavior of material subjected to simple beam loading. The most commonly recorded results from this test are maximum fiber stress and maximum strain, and are plotted on a stress vs strain graph. The flexural strength is defined as the maximum stress in the outermost fiber and is calculated at the tensile surface of the specimen. Flexural modulus is calculated from the initial slope of the stress vs. strain graph and if the curve has no linear region, a secant line through the graph origin is fitted to the curve to determine slope.
