This standard specifies a method of testing a small insulated wire under fire conditions when the method specified in IEC Publication 332-1 is not suitable because some small conductors may melt during the application of the flame - The range of application recommended is for solid copper conductors from 0.4 mm to 0.8 mm diameter and for stranded conductors from 0.1 mm2 to 0.5 mm 2 cross-section - This standard includes the requirement for compliance - Note: The use of insulated wire which complies with this standard is not sufficient to prevent flame propagation under all conditions of installation - When the risk of propagation is high, such as with long vertical runs of bunches of wires, it cannot be assumed that, because a sample complies with this standard, the bunch will behave in a similar manner
