XQZ-20 Dichloromethane Resistance Tester (Dich/oromethane soak testing machine) , General introduction Methylene chloride tester/Dichloromethane soak testing machine is used to determine the resistance of unplasticised polyvinyl chloride (PVC-U) pipes to dichloromethane (methylene chloride) at a specified temperature (DCMT). important product quality ct strength and various methods to s ana profiles; the most common one is to use Methylene with EN 580 method B, ISO 9852 and The gelation of PVC is one of the considerations as it has an influ resistance to internal pressure determine the gelation level in chloride according to various stan equivalent. Application: For plastic pipes, pipe fittings, sheet under the temperature of 5'C 65'C and dichloromethane _ iipes - Test mel J,h EN 580 "Plastics piping systems - Unplasticized poly(vinyl chloride) (PVC-U) pipes - Test method for the resistance to dichloromethane at a specified temperature (DCMT)" A piece of PVC-U pipe, of specified length, chamfered at one end to an angle dependent on its thickness, is immersed for (30 ± 1) min in dichloromethane, at a temperature T specified by the referring standard, to verify that the PVC-U is not attacked at that temperature. For safety reasons, the surface area of the dichloromethane is kept to the minimum and the dichloromethane is covered by a deep layer of water to reduce evaporation. After immersion in the dichloromethane, the test piece is held in the water layer to allow it to "drip" before final drying and inspection.
