Description
EN 60811-507 and IEC 50811-507 describers the method of testing Hot set of a crosslinked thermoplastic. The purpose of this test is clearly to assess the degree of crosslinking achieved in the plastic used for extrusion.
The test result informatively shows the extent of crosslinking between Carbon and hydrogen molecules of a hydrocarbon used as plastic here.
The norm suggests to use dumbbell samples marked with 20 mm or 10mm distance in the middle of the sample equally distant from center.
Upon putting the samples with prescribed weight, temperature and clips to hang and time required, the elongation is measured in the sample to understand degree of crosslinking.
After wards, it is also possible to do a permanent set test of the same sample to evaluate thermoset behavior of the plastic used. To be noted that the thermoset behavior depends on the crosslinking as well and its directly proportional.
Our EN 60811-507 compliant hot set test ovens have different types.
- With Laser guided gauge and automatic reporting system (Through HMI)
- With manual scale measurement and reporting
