1 ; a) Overcharging at constant current during t 2 . Overcharging intensity is specified by manufacturer and corresponding to that used during equalisation charging. The end of REESS charge criteria corresponds to an automatic stop given by the charger to a charging time oft b1b + t 2 . This charging time will be limited tot b1b + 5 h, even if a clear indication is given by a suitable instrumentation that the REESS is not yet fully charged. 5.2.4.8. The hydrogen analyser shall be zeroed and spanned immediately before the end of the test. 5.2.4.9. The end of the emission sampling period occurs t
