Information about tests

penetrability of fat/ fat- proof test

Testing of paper, coated paper or plastic films with pigmented palm kernel fat. The sample is covered on the test surface with the test fat and then the glass pane and, if necessary, additional weights are placed on top.At the end of the exposure time, the grease spots up to 1 mm in size, visible to the naked eye on the display paper within the defined test area, are evaluated. If only grease spots up to 1,0 mm are observed, the test is considered to have been passed; in the case of grease spots larger than 1,0 mm, the test has to be performed with a more moderate test condition (a "poorer" grease permeability group).

test method:Mechanical/ technological properties
Norms: DIN 53116 (2003-02)
Needed sample size:minimum sample size: 3 x DIN A 4 per grease pernetrability group (n = 10 samples á 100 * 100 mm), optimum: take 1 m² samples over the full width of the material
