Fire hazard testing. Test flames - Confirmatory tests. Guidance algolia-search-ignore — backfilling of open mines1 Scope 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
