Abstract

The invention relates to a test specimen (1) for rheological testing of plastic products comprising a plate body (10) from a plastic material, said plate body (10) having a first major surface (102), a second major surface opposite to the first major surface (102) and a side surface (106) connecting the first and the second major surface (104) and at least one spatial feature (12A, 12B, 14A, 14B) arranged in or on the plate body (10), each spatial feature (12A, 12B, 14A, 14B) indicative of a defect occurring in the plastic products or a geometric feature of the plastic products. The invention relates further to methods and respective systems using the test specimen, including methods and systems for testing for testing of a plastic product, for validating a rheological data set or a model of a process for manufacturing of plastic products, for determining at least one property of a plastic product to be manufactured and for manufacturing a plastic product.
