This standard specifies a method of test on a single vertical insulated wire or cable and the requirement for compliance.
Notes I. — Since the use of insulated wire or cable that complies with the requirement is not sufficient by itself to prevent propagation of fire under all conditions of installation, it is recommended that wherever the risk of propagation is high, for example in long vertical runs of bunches of cables, special installation precautions should also be taken. It cannot be assumed that because the sample of cable complies with the performance required in this standard that a bunch of cables will behave in a similar manner.
2. — The method specified is not suitable for the testing of some small wires due to the melting of the conductors during the time of application of the flame.
