Описание (английский):

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).

Overview

ISO 29473:2010 - Fire tests - Uncertainty of measurements in fire tests provides guidance on evaluating and expressing measurement uncertainty for quantitative fire test results. It applies to measurements reported in engineering units (for example, heat release rate measured by oxygen consumption calorimetry as in ISO 5660-1). The standard does not apply to index-based or binary (pass/fail) fire tests. It is based on the general framework of ISO/IEC Guide 98-3 and adapts those principles to the specific challenges of fire testing.

Key Topics

Scope and limitations: Applies to quantitative outputs only; sampling uncertainty and very low-level results may need extra guidance.

Fundamental principles: Definitions of measurand, error, random vs systematic contributions, and treatment of residual systematic error.

Evaluation methods:

Type A evaluation (statistical analysis of repeated observations).
Type B evaluation (a priori estimates from calibration certificates, manufacturer data, historical experience).

Combination of uncertainties: Procedures for combining individual standard uncertainties into a combined standard uncertainty and calculating expanded uncertainty using a coverage factor.

Reporting requirements: Guidance on how to present uncertainty estimates in test reports.

Practical examples and annexes: Annex A covers basic concepts; Annex B discusses uncertainty of fire test results; Annex C provides an example for cone calorimeter heat release measurements.

Applications

Estimating and reporting the uncertainty of heat release rate, mass loss, or other quantitative fire test outputs.

Supporting compliance with laboratory accreditation requirements (e.g., ISO/IEC 17025), which require uncertainty statements with reported results.

Providing input uncertainty data for fire modelling, risk analysis, and engineering decision-making where quantitative fire test data are used.

Informing development or revision of test methods within ISO/TC 92 subcommittees.

Who should use ISO 29473:2010

Accredited fire testing laboratories and technicians preparing test reports.

Fire safety engineers and researchers using quantitative test data in analysis and models.

Standards developers and conformity assessment bodies needing consistent uncertainty treatment.

Calibration and metrology professionals engaged with fire test instrumentation.
