This Part 408 of IEC 60811 gives the procedure to establish as to whether or not the quality of
a cable's components will be satisfactory over the proposed life of a communication cable.
This test is considered only as a material selection test to ensure that the chosen materials
are satisfactory for the intended life of the cable. The test duration makes the test unsuitable
for routine quality control testing; one method found suitable for monitoring raw materials is
given in IEC 60811-410.
