B.7Earthing of armour
Provision should be made for earthing the armour to the main earth system at the supply end by means of a metallic bond of adequate conductance,the bonding connection being asshiort and straight as possible Special precautions maybenecessaryto eliminate therisk of corrosion,especially corrosiondue to the use ofdissimilarmetals.

B.8Test after installation
A voltage test after installation is not a requirement of this standard, but if a test is made it should be
TableB.2Testvoltagesafterinstallatio
During the test, the voltage should be increasedgraduallyto the full value and maintained continuously for 15 min. The test should be made between conductors and between each conductor and armour. Nobreakdownshouldoccur. Sequencetesting maybe used to reduceoverall testingtimefor multicoreauxiliary cables,as indicated inAnnexK. Thetest voltages given in TableB.2 areintended for cables immediatelyafter installation and not for cables that havebeen in service. When testing is required aftercables have been in service, regardless of service duration,the manufacturer should be consulted for the appropriate test conditions, which depend ontheindividualcircumstances.
