2. Cable and hose packages:
No. 1: 1x CFROBOT.036 with the cable marking

IGUS Chainflex CFROBOT.036 1x16 E113308 cяUuS AWM 1x4 AWG Style 21387 AWM I/II A/B
90°C 1000V FT1 CE RoHS conform

3. Description of the cable construction:
Standard igus chainflex® catalogue cable.

4. Remarks:
To detect broken conductor or shielding wires we will measure the ohmic resistance of these cableelements. The cores of the samples are connected in series and one core is connected with the shielding
to measure the ohmic resistances.

ResultStart report 12.05.2009:
At the 12.05.2009 we started the test 3351 at counter reading 8.060.294, we will measure the ohmic
resistance regularly.
Interim report 10.05.2012
At the 10.05.2012 we demounted cable no. 1.1 after 17.099.049 cycles to finalize the test
