This part of IEC 60794 defines the test procedure to determine the ability of an optical fibre cable to withstand bending around a test mandrel. The primary purpose of this procedure is to measure the change in attenuation when the cable is bent around a test mandrel. A secondary purpose is to assess whether the cable has been physically damaged by bending.
NOTE 1 This test can be utilized at any specified temperature, including the low or high temperature limits for the cable.
NOTE 2 The bend test procedure for cable elements is specified in IEC 60794-1-301, method G1.
