& Ecosafene Products Service Co.,Ltd have rich experience to provide French Standard NF P92-505 fire test to Building Material
NF P92-505 Fire test to Building materials - Standard
NF P 92-505: Dripping test with electrical radiator, used for melting materials.
If for NF P 92-501 and NF P 92-503 testing, there melt drops off, with or without combustion phenomenon, should conduct the test NF P 92-505. Comprehensive assessment M classification.
NF P92-505 Fire test to Building materials - Standard Brief
NF P 92-505 combustion is used to test whether the produced materials can be ignited lint (asbestos gasket) of the droplet. If the fire reaction tests in other non-combustible material or material generated droplet could not be determined rapidly shrinking spread of flame, drip test should be conducted, according to test results will be material dropping into M1 ~ M4 rating.
NF P92-505 testing requirements: the sample is placed horizontally on the sample rack, the vertical distance of30mm at its office, horizontal level of a power of 500W electric radiators, heat the sample to impose a certain amount of radiation in the sample under 300mm vertical distance by placing a receiving tray, drip tray lighted place for lint (asbestos gasket), test 10min. The testing processes while observing the flame, and if the sample is ignited before the 5min electric radiators should be removed, have radiation after 5min. The combustion of the samples, smoke and other associated phenomena in record. If lint (Asbestos Gasket) is lit, then determine the grade for the M4.
