Accessories Provide Increased Testing Functions

Materials and quality requirements increase continuously, along with the need for improvements in mechanical testing.

Materials and quality requirements increase continuously, along with the need for improvements in mechanical testing.

That is according to Zwick Roell, which said that with a doubling of sales in the last five years, the company's range of testing accessories helps its customers to stay ahead of competitors by adding increased functions to existing testing equipment.

Because the equipment can be used on most brands of testing equipment, users can benefit from Zwick's experience in manufacturing manual, pneumatic or hydraulic specimen grips, analogue, digital, contact or non-contact extensometers, temperature chambers, compression or flexure tooling and other special fixtures, claimed the company.

The improved measurement capability of modern testing systems means that they can register the smallest of changes in the specimen and so specimen grips are particularly important because the performance of any testing system is dependant on the ability to correctly grip the test specimen, commented Zwick.

The requirements for grips are especially diverse, said the company.

On one hand, they must be adapted to geometry of the specimen and the type of test and on the other hand they must operate correctly in the required environmental conditions.

Zwick said it provides a range with different inter-changeable components, such as jaw faces and adapters, which can be selected according to the test application.

They include conventional tensile tests, combined tensile and compression tests, shear, peel, bonded joints, wet tensile tests (for example, on paper) and others.
