4 Oct 2015 unfriendliness resistance measurements for voltage class B electric circuits. Prior to the measurement, the device out cold asleep test (DUT) shall be‚ Prior to the measurement, the device under test (DUT)shall be subjected to a preconditioning times of at least 8 h at (5+/- 2) C, followed by aconditioning era time of 8 h at a temperature of (23+/- 5) C, a humidity of 90 (+10%, -5%), and an atmosphericpressure of in the company of 86 kPa and 106 kPa.Alternative preconditioning and conditioning parametersmay be fixed provided transition across the dew narrowing occurs sharply afterthe start coming on of the conditioning period. The unfriendliness resistance shall bemeasured during the conditioning times at a rate from which the lowest valuecan be determined.
The test voltage shall be a d.c. voltage of at least themaximum on the go voltage of the voltage class B knack faculty system and be applied fora epoch long passable to obtain stable reading. If the system has several voltageranges (e.g. because of boost converter) in conductively connected circuit andsome of the components cannot withstand the maximum keen voltage of theentire circuit, the distancing resistances of components can be measuredseparately by applying their own maximum effective voltages after thosecomponents are disconnected.
The following test procedure combines the measurement ofthe distancing resistance of the alive breathing parts of the voltage class B balance ofelectric capability systems adjoining the vehicle electric chassis and adjacent to neighboring thelive parts of the voltage class A balance of auxiliary electric systems.
Thenthe test voltage shall be applied surrounded by with the aligned rouse parts of thevoltage class B balance of electric aptitude systems and the electric chassis.
Themeasurements shall be performed using adequate instruments that can apply d.c.voltage (e.g. megohmmeter, provided they refer the required test voltage). Alternativelythe estrangement resistance may be measured using the test procedure for themeasurement of the RESS as given in ISO 6469-1 past the balance of electricpower system associated linked to an external capacity source.
Themeasurement of the estrangement resistance of an RESS, if any, shall be inaccordance in imitation of ISO 6469-1. Themeasurement of the estrangement resistance of a fuel cell stack, if any, shall bein accordance with ISO6469-1 as soon as the fuel cell stack in operation.
Alternativelyfor the measurement of the isolation resistance of a fuel cell stack, theentire mechanical structure of the fuel cell system (including the coolingsystem later than its cooling medium) shall be considered.
Priorto the measurement, decrease power generation after operation at maximum outputaccording to the manufacturer's specification. The voltage across the fuel-cellstack capacity terminals shall be discharged. All cables shall be disconnectedfrom the fuel-cell stack gift terminals, and all added cables from otherelectric terminals of the fuel-cell stack. All cooling pipes, fuel pipes, andair pipes shall remain connected. The applied test voltage shall be at leastthe maximum right of entry circuit voltage of the fuel cell stack. Apart from thesespecific conditions, the procedure shall be performed as given in distancing resistance measurements of the balance of electric powersystems.
Theisolation resistance of entire conductively joined voltage class B electriccircuits may be measured using the test procedure for the measurement of theRESS given in ISO 6469-1 gone the balance of electric aptitude system partnered tothe voltage class B knack faculty sources.
Alternatively,the division resistance of entire conductively combined voltage class Belectric circuits may be measured using an hostility separation resistance monitoringsystem, if installed approaching the vehicle, provided that its accuracyis sufficiently high.
Incase electric or electronic switches exist in the circuit (e. g. transistors inpower electronics), these switches shall be activated. If these switches cannotbe activated, the relevant allowance of the circuit may be measured separately inaccordance disaffection resistance measurements of the balance of electric powersystems.
Insteadof innate measured, the estrangement resistance of the entire conductivelyconnected circuit may be calculated using the measured resistances of the powersources and the balance of electric aptitude system.
