This part of IEC 60695 presents a general characterization of small-scale test flames and associated confirmatory tests based on copper block calorimetry@ and defines theoretical modelling for the associated dynamics. Guidance is presented for the selection of critical parameters in confirmatory test designs. A theory is presented to define additional performance parameters for confirmatory tests@ enabling a precise implicit mathematical characterization of confirmatory test heating curves. One of the responsibilities of a technical committee is@ wherever applicable@ to make use of basic safety publications in the preparation of its publications.
