Annex C (informative) Nomenclature

Defines the calculation procedure for converting the data generated by chemical analysis in IEC 60695-7-50 into predicted toxic potency data for material tested under defined conditions.

Describes the calculation procedure for converting the data generated by chemical analysis in IEC 60695-7-50 into predicted toxic potency data for material tested under defined conditions. This is in order to estimate the contribution of the fire effluent of an end-product or material to the toxic threat to life of the total fire effluent resulting from a fire scenario in which the end-product or material is involved. This method may also be suitable for converting data from other relevant test methods into predicted toxic potency, provided that the form and format of the data is compatible with that of IEC 60695-7-50. This method is intended to be consistent with the principles advanced in IEC 60695-7-3, and ISO/TR 9122-5. It is designed specifically to make use of results in the form expressed in the laboratory test method described in IEC 60695-7-50. Toxic potency values are only of use in toxic hazard estimations, and must not be used in isolation. Has the status of a basic safety publication in accordance with IEC Guide 104.
