If you are comparing the 2000 version to the , look for these critical updates:
: Specifically addresses power frequencies between 50 Hz and 60 Hz.
Without the standard, you would never know the difference until the first fault kills a technician.
The 2013 edition refines the allowable body current based on updated biomedical research. The standard now uses a 50 kg (110 lb) and 70 kg (154 lb) body weight model more accurately. The tolerable step and touch voltages are recalculated using these refined models, generally resulting in slightly more conservative (safer) limits than the 2000 edition for the same fault clearing time.
