Water was added and the volumes of w ater taken in by the materialwere calculated from the weight increase.In thetest, the plastic laminate is rubbed continuously by an abrasivewheel. The material is examined every 10 hours, and the deterioration of thematerial is measured. This testing provides an estimate of the plastic product'lifetime span.Thetest was carried out by means of a tensile test. A ."vire wasstretched to breaking point, and the percent of elongation (lengthening) wascalculated.
After the test, the wire retained its changed shape when the loadwas removed.Thetest is similar to a flexibility test. A material is placed repeatedlyunder increased loads. The test determines whether an bending can be measured.and if so, how much.[n a test of, a sheet of the test material is placed on a doming blockand is hit repeatedly with a metal punch.
