摘要

The draft decision regarding the Euroclassification of cables was finally approved by the Standing Committee on Construction in April 2006. After publication in the Official Journal there will be a three year period of coexistence with existing national test requirements which will then start to be withdrawn in favour of the new regulations. The new cable classification system includes criteria for acid gas. Over the past 5 years considerable effort has been devoted to validate the scientific basis of the approach. The results of bench scale fire effluent toxicity assessments of 10 cables are reported and correlated with acid gas data. An estimation of the component contribution to the fire gas toxicity of each of the cables, measured under the three fire conditions indicates that although CO is a significant contributor to fire effluent toxicity, the presence of acid gases is the major differentiator between the different types of cables tested. Results are compared with previously published large scale toxicity data for 5 of the cables tested in the current program.
