Does Acidity discriminate all the cables emitting hazardous gasses?
No, there are cables that emit in case of fire hazardous gasses which are not acid. ISO 13571 : 20071 gives the needed distinction of hazardous gases between asphyxiants2 – and irritants gases. Acidity is a measure for irritant gases which are influencing the escape time. (1) ISO 13571 : 2007 Life-threatening components of fire — Guidelines for the estimation of time available for escape using fire data; ISO 13571:2007 provides guidance on establishing the procedures to evaluate the life threat components of fire hazard analysis in terms of the status of exposed human subjects at discrete time intervals. It makes possible the determination of a tenability endpoint, at which time it is estimated that occupants are no longer able to take effective action to accomplish their own escape. The life threat components addressed include fire-effluent toxicity, heat and visual obscuration due to smoke.
