Описание (английский):

ISO 19701:2013 presents a range of sampling and chemical analytical methods suitable for the analysis of individual chemical species in fire atmospheres. The procedures relate to the analysis of samples extracted from an apparatus or effluent flow from a fire test rig or physical fire test model and are not concerned with the specific nature of the fire test. It does not cover aerosols and Fourier transform infrared (FTIR) technique.

Overview

SIST ISO 19701:2018 (identical to ISO 19701:2013) specifies methods for sampling and chemical analysis of fire effluents - the gases produced by combustion in fire tests. The standard focuses on laboratory sampling from test rigs or physical fire test models and sets out procedures to present representative, analysable samples from hostile fire atmospheres to analytical instrumentation. It explicitly excludes aerosols and FTIR techniques and does not address the specific nature of individual fire tests.

Key technical topics and requirements

Sampling fundamentals and best practice

Emphasis on representative sampling, minimal disturbance of the test atmosphere and quantification of sampling losses (probes, lines, filters).
Considerations for concentration vs. volume fraction, temperature and pressure corrections, and avoidance of condensation or probe blockage.

Sampling approaches

Gas–solution absorbers, solid sorption tubes, spectrometric/spectrophotometric sampling, and gas bag collection.

Analytical methods for fire gases (clause highlights)

Instrumental techniques such as NDIR for carbon monoxide (CO) and carbon dioxide (CO2), paramagnetic oxygen measurement, HPIC for sulfur dioxide (SO2), and GC–MS for species like carbon disulfide.
Specific methods for toxic and corrosive species: hydrogen cyanide (HCN), hydrogen chloride (HCl), hydrogen fluoride (HF), oxides of nitrogen (NOx), aldehydes (formaldehyde, acetaldehyde, acrolein), hydrocarbons, isocyanates, and various metals by AAS or ICP.

Supportive annexes

Annex A: techniques unsuitable for fire effluents
Annex B: aspirated chemical colour‑change tubes
Annex C: summary of quantitative instrumental methods
Annex D: continuous HF measurement (ion selective electrode)

Safety and uncertainty

Strong safety guidance for handling toxic gases and reagents and advice on estimating measurement uncertainty from instrument data and sampling losses.

Practical applications

Conducting toxic hazard and life‑threat assessments during fire testing.

Chemical characterization of effluents from material and product fire tests for fire safety research, regulatory compliance, and environmental impact studies.

Generating validated compositional data to inform evacuation models, smoke toxicity evaluations, and product certification.
