ML Tensile Tester MD / CD

In contrast to other techniques for determining tensile strength, the ModularLine tensile strength test device is a fully-fledged measurement device as specified according to ISO 1924-3. With this device, direct measurements of strain are possible, and require no correction factors. A sample is automatically punched, according to model, in MD or CD at a width of 15 mm. A fullyfledged tensile testing module within the device guarantees standards-compliant testing, with results that can be directly compared with laboratory devices. Therefore, neither correction or correlation is required. Together with a ModularLine single transport (see page 12) or as part of a ModularLine, an informative cross-section profile of the tensile strength of a sample can be easily and fully automatically created.

Test Description

A strip of 15mm in width is automatically created from the inserted sample using an integrated punch. This strip is then held by a vacuum pump and transported lower. There the jaws of the clamp close and the test procedure begins. The clamp jaws pull the sample so far apart that it rips. After a successful test, the destroyed sample is automatically blown into a refuse container. Along with the process curves recorded, the strain, maximum breaking force, tension length, and tensile strength, among other values, are calculated.
