NFPA 70E Nomex III ratings

[E1tech]

We have just read through NFPA's 70E regarding personal protective equipment (PPE). Does any one know what they mean by the "APTV" rating? Also does anyone know what the APTV rating is for 6oz. Nomex III FR clothing?

ATPV in this case probably means "arc thermal performance value". You may find applicable information at sites like

Check with Oberon, they manufacture Nomex suits.
