Mechanical testing is integral to bringing a design into production. Calculated values alone do not necessarily give an accurate picture of how materials and products will integrate together. Mechanical testing provides empirical data to ensure that products meet specifications and comply with required regulations and quality standards.
During tensile testing, a sample is subjected to a uniaxial tensile load until failure. Tensile load is generally applied at a specified rate to determine material properties including yield strength, maximum elongation, reduction in area, ultimate tensile strength. Often used for quality control and material selection.
Axial; Longitudinal; Transverse - AS 1391; ASTM A370; ASTM E8M; F606M; ISO 6892-1
Includes nuts, bolts, studs and assemblies. Used for quality control, product verification, pre-use proof loading and to validate batches to be supplied for Queensland and NSW government projects.
Hardness - AS 1252.1; AS 4291.1; AS/NZS 4291.2
Tensile including Wedge Test - AS 1252.1; AS 4291.1; AS/NZS 4291.2; MRTS 78; RMS B240

Chemical composition testing (chemical analysis) is used for material identification. Optical emission spectrometry details the percentages of various elements or compounds present in a supplied specimen. Other methods are also available for determining material composition.
A charpy impact test measures the energy absorbed during the breaking of a notched sample under an impact load.
Charpy V-notch impact test (-196°C and -20 to 174) - AS 1544.2; AS 1544-5; ISO 148-1; ASTM E23; ASTM A370
Indentation hardness tests are used to determine the resistance of a material to deformation.
The sampled material is indented under a specified load and an impression is formed, measured and hardness calculated.
Vickers and Rockwell - AS 1817.1; AS 1815.1; ASTM E384; ISO 6507-1; ISO 6508-1
Testing to the requirements for cold-formed steel hollow sections for structural purposes, for the six grades of steel that are suitable for welding.
Tubing/Piping (Flattening) - AS 1163
Hydrostatic pressure is used to confirm that a tested specimen conforms to its design criteria. Involves placing a liquid medium (often water) into the pipe, pipeline, cylinder, vessel, valve assembly or other article. The pressure is increased to the requisite level to check for leaks and defects. Testing is usually done to a proof level but can be taken to destruction if necessary. (MechTest have capability to 25000psi)
AS 1210; AS 3788; AS 4037; AS 4041
It is difficult to list all the possiblities that arise in the field of mechanical testing. We are a Nata accredited laboratory with extensive experience. We also partner with experts in a multitude of environments.
