This standard applies to terrestrial line-of-sight digital radio microwave relay communication channel transmission equipment and ground line-of-sight analog FM radio microwave relay communications that use mean time between failures (MTBF) as an indicator and whose expected life obeys an exponential distribution or is reasonably believed to obey an exponential distribution. Reliability qualification test and reliability acceptance test of channel transmission equipment. Terminal equipment supporting microwave equipment that can meet the above conditions can also be implemented by reference. This standard does not apply to reliability growth tests.
