Small‐scale flame tests were conducted on samples of six different rubber conveyor belts with fabric skeletons for use in Japanese coal mines. Each sample was claimed to be ‘flame‐resistant’ under the test condition prescribed in JIS K 6324‐1977, but results show that there are problems in this kind of test. Every sample tested sustains flame continuously when the flame exposure time exceeds a certain value or ‘ignition time’. In addition, flame duration seems to depend on the flame‐resistance of the fabric skeleton as well as on flame exposure time.
