Alcohol burner fire test is a important basis to measure flame retardant wire rope traction with flame retardant, is also the important project of the test, the test method and judgement are referenced MT449 a 1995 is carried out. In the general test, can use simple method is as follows:
(1) in the 50 mm away from ear canal with special cutting knife in vulcanizing machine directly (or other pressure machine) cropping 24 piece contains no metal horizontal pieces on the transverse specimens, take 12 piece of strip using the method of grinding the upper and lower layer。
(2) on the ear of the tank from flame-retardant wire rope traction belt cut (note that keep the cutting surface smooth, then cut into 6 pieces of 150 mm long specimen.
(3) under the ear of the tank from flame-retardant wire rope traction belt cut (note that keep the cutting surface smooth, then cut into 6 pieces of 150 mm long specimen。
(4) specimens shall be placed, it is low end away from the alcohol burner height of the crater to 50 mm, alcohol blowtorch vertically。 Test combustion under low light box, light alcohol burner, adjust its flame height is 150 a 180 mm, fuel consumption is 2。55 mL/min + o。 15 mL/min。 (5) when the test specimen with the surrounding air flow should be small, does not affect the burning with fire of the specimens。 Trial container of fuel liquid level height should be kept at 760 mm from the bottom of the alcohol burner + 20 mm range, specimen in central flame, its leading edge and the edge is consistent, perpendicular to the door of the burning box。 6。 Put the specimen when testing the flame burning in the 30 s, remove not extinguish alcohol burner, and risen from the smallest degree of 0。01 s stopwatch with flame combustion on the specimen and flameless combustion time。
