ISO 29473:2010 gives guidance on the evaluation and expression of uncertainty of fire test method measurements.
Application of ISO 29473:2010 is limited to tests that provide quantitative results in engineering units. This includes, for example, methods for measuring the heat release rate of burning specimens based on oxygen consumption calorimetry, as in ISO 5660-1:2002
ISO 29473:2010 does not apply to tests that provide results in the form of indices or binary results (e.g. pass/fail).
