Full title and description

STB BS ISO 29473-2010 — Fire tests — Uncertainty of measurements in fire tests. This document provides guidance for evaluating and expressing the measurement uncertainty associated with quantitative fire-test methods (for example, heat-release measurements based on oxygen-consumption calorimetry).

Abstract

ISO 29473:2010 gives guidance on the evaluation and expression of uncertainty for measurements obtained from fire test methods that produce quantitative results in engineering units. It is intended to help test laboratories, method developers and users to estimate and report the uncertainty associated with measured quantities (for example heat-release rate) and excludes tests that only yield indices or binary (pass/fail) outcomes.

Scope

Provides guidance on the evaluation and expression of measurement uncertainty for fire-test methods that return quantitative engineering-unit results (for example, heat-release-rate measurements from cone calorimetry). The standard applies to measurements where numerical values are produced and does not apply to test methods that only give indices or binary outcomes (pass/fail). It is intended to be used alongside specific fire-test methods (for example ISO 5660 series) when estimating the uncertainty of reported numeric results.

Key topics and requirements

• Framework and principles for evaluating components of measurement uncertainty in fire tests (identification, quantification and combination of uncertainty components).
• Guidance on expressing combined and expanded uncertainty for quantitative test results.
• Application examples and references to common fire-test measurement techniques (e.g., oxygen-consumption calorimetry used in ISO 5660‑1).
• Limitations — not applicable to indices or purely qualitative/binary test outputs.

Typical use and users

Primary users include accredited fire-test laboratories, standards developers and method authors, manufacturers submitting quantitative fire performance data, certification bodies and researchers working on fire performance measurement and modelling. The standard is used when reporting numeric results (for example heat release rate, mass-loss rate or smoke production where reported as engineering quantities) to provide a transparent estimate of measurement uncertainty.

Related standards

Closely related to reaction-to-fire and fire-test method standards — notably the ISO 5660 series (cone calorimeter and heat-release measurements) which are common test methods producing the quantitative results for which ISO 29473 gives uncertainty guidance. The standard is developed under ISO/TC 92/SC 1 and should be used alongside specific test-method standards in that series.

FAQ

Q: What is this standard?

A: ISO 29473:2010 is an international guidance standard titled "Fire tests — Uncertainty of measurements in fire tests" that explains how to evaluate and express uncertainty for quantitative results from fire-test methods.

Q: What does it cover?

A: It covers methods for identifying, quantifying and combining components of measurement uncertainty for fire tests that produce numerical engineering‑unit results (for example heat‑release rate measured by oxygen‑consumption calorimetry). It explicitly excludes methods that only provide indices or pass/fail outcomes.

Q: Who typically uses it?

A: Accredited fire-testing laboratories, standards developers, certification bodies, test-method authors, manufacturers providing quantitative fire-test data, and researchers requiring a formal estimate of measurement uncertainty for reported numeric fire-test results.

Q: Is it current or superseded?

A: ISO 29473 was published in 2010 as edition 1 (ISO 29473:2010). Users should check with national bodies or ISO for any confirmation, amendment or review status relevant to their country or sector before applying the standard in regulated contexts.

Q: Is it part of a series?

A: It is not a multi-part series itself, but it is intended to be used alongside specific fire-test standards (for example the ISO 5660 series on reaction-to-fire tests) developed by the same technical committee (ISO/TC 92/SC 1).

Q: What are the key keywords?

A: Fire tests, measurement uncertainty, uncertainty evaluation, heat release rate, cone calorimeter, oxygen-consumption calorimetry, ISO 29473.
