The specimen is deemed to have passed this test, if afterburning has ceased, the charred or affected position does not reach within 50mm of the lower edge of the top clamp which
is equivalent to 425mm above the point of flame application. The test method is not suitable for the testing of some smallwires due to the melting of the conductors during the time of application of the flame.
