There is an immediate industrial need for new, validated and standardised measurement methods capable of high-resolution dimensional and mechanical property mapping of viscous materials. Viscous materials (such as polymers) continuously deform over time. This not only makes polymeric parts subject to dimension change that limits their useful lifetime, but invalidates current measurement methods, which assume a time independent material response. The joint European research project MeProVisc provides validated indentation and contact measurement methods to measure the shape, mechanical properties and deformation rate of viscous materials. This workshop will provide early exposure and introductory training to the project validated methods that are being proposed as new International standards.
One application of the project results is the precision measurement of polymer layer thickness on hard substrates. This is usually difficult, since many polymers are transparent and hence difficult to measure by optical methods but at the same time difficult to measure for tactile instruments like stylus instruments or scanning force microscopes due to their softness. Systematic deviations of the measured film thickness of several hundred nanometres are not uncommon. The workshop will present a new method to correct tactile thickness measurements (see also DIN 32567).

Agenda, PTB-Workshop, Sept. 23 You can combine search terms with and, or and/or not, e.g. Philo not logy.
You can use brackets to separate combinations from each other, e.g. (Philo not logy) or (Psycho and logy).
Coherent groups of words will be located as complete phrases if you put them into quotation marks, e.g. “Federal Republic of Germany”.
You can also use the advanced search without entering search terms. It will then follow the criteria you have selected (e.g. country or subject area).
If you have not selected any criteria in a given category, the entire category will be searched (e.g. all subject areas or all countries).
