ISO 527-2:2012 Tensile Properties of Plastics
The challenges of testing to this standard are:
- Repeatable strain measurement
- Secure gripping of varying specimens
- Reporting calculations in compliance with the standard
- Repeatable strain measurement – An extensometer is required by the standard to accurately measure strain. Advanced strain solutions include non-contacting extensometers, such as the Advanced Video Extensometer 2 (AVE2) and automatic contacting extensometers, such as the AutoX 750. These solutions have the accuracy to measure modulus as well as strain to failure and require little influence from the operator which can resulted in improved repeatability. A 75mm gauge length clip-on extensometer, such as 2630-123, also meets the measurement accuracy stated in ISO 527-2:2012. For quality control testing a 50mm gauge length extensometer, such as 2630-111, is still compliant.
- Secure gripping of varying specimens – Mechanical wedge grips or pneumatic side-acting grips with serrated faces are suitable for most rigid and semi-rigid plastics.
- Reporting calculations in compliance with the standard – Instron Bluehill® Universal testing software has advance pre-built methods available with pre-configured plastic specific calculations helping to ensure compliance.
It is important to review ISO 527-1:2012 and ISO 527-2:2012 in order to fully understand the test setup, procedure, and results requirements.
The second generation Advanced Video Extensometer (AVE 2) utilizes patented measurement technology in the fastest, most accurate non-contacting strain measurement device commercially available. The device dramatically reduces errors from thermal and lighting variations that are common in most labs. It can easily be adapted to nearly every testing system in your lab.

The AutoX 750 is a high-resolution, long-travel automatic contacting extensometer. It can be mounted onto any electromechanical 3300, 5500, or 5900 table top and floor model systems, as well as LX, DX, HDX, and KN static hydraulic testing systems. It is well suited for applications involving plastics, metals, biomedical, composites, elastomers, and more. The AutoX has a maximum travel of 750 mm and accuracy of ± 1 µm.
