The NSR floor resistance to heat and moisture test cylinder is used to test the surface resistance to heat and moisture of wooden flooring used for floor heating to determine the resistance of the decorative layer on the surface of the specimen to hot objects in a humid state. The floor moisture and heat resistance test drum complies with LY/T1700 standard.

1. Pour 0.5L boiling water into the floor heat and humidity resistance test drum.
2. After installing the test piece in parallel, pour boiling water on the surface of the test piece, and place the floor humidity and heat resistance test drum filled with boiling water on the surface of the test piece.
3. After leaving it for 20 minutes, remove the heat and humidity resistance test drum, dry the surface of the test piece with a towel, and leave it for another 24 hours.
4. Under natural light, observe whether there are cracks, bubbling, or discoloration on the surface at a distance of about 40mm from the surface of the specimen.
