Overview

ISO 29904:2013/Amd 1:2026 is an amendment to the international standard ISO 29904, which addresses fire chemistry with a focus on the generation and measurement of aerosols. Published by the International Organization for Standardization (ISO), this standard is developed by Technical Committee ISO/TC 92, Subcommittee SC 3, Fire threat to people and environment. The amendment introduces a terminology update that replaces the trademarked term "Engine Exhaust Particle Sizer (EEPS)" with the more generic "Electrical Aerosol Spectrometer (EAS)" throughout the document. This change ensures clarity and neutrality in references to aerosol measurement instrumentation within the field of fire chemistry.

Key Topics

• Fire Chemistry: Understanding the chemical processes involved in combustion and fire-related scenarios.
• Aerosol Generation: Methods and standards for reproducing fire aerosols in a controlled manner.
• Aerosol Measurement: Accurate quantification and characterization of aerosols using electrical aerosol spectrometers.
• Standardized Terminology: Consistent language to facilitate better communication and application across industries and research.
• International Collaboration: Developed through inputs from member bodies worldwide, ensuring global relevance and harmonization.

Applications

ISO 29904:2013/Amd 1:2026 is vital for a range of industries and sectors, including:

• Fire Safety Research: Provides a framework for laboratories studying the properties and hazards of fire-generated aerosols.
• Environmental Protection: Supports regulatory agencies and organizations monitoring fire emissions and their impact on air quality.
• Product Development: Assists manufacturers of aerosol measurement devices, ensuring their instruments align with recognized global standards.
• Risk Assessment: Equips fire safety engineers and consultants with standardized procedures for evaluating aerosol-related hazards.
• Academic and Industrial Studies: Facilitates comparative studies by establishing clear definitions and measurement protocols.

By using a consistent and generic reference to measurement technologies (Electrical Aerosol Spectrometer), the amendment promotes neutrality and avoids potential bias towards proprietary solutions. This fosters broader adoption and innovation within fire chemistry testing and aerosol analysis.

Related Standards

For organizations and professionals working with fire chemistry and aerosol measurement, the following standards are also relevant:

• ISO 29904:2013 - Fire chemistry - Generation and measurement of aerosols (original edition)
• ISO 13571 - Life-threatening components of fire - Guidelines for the estimation of time to compromised tenability in fires
• ISO 5660 - Reaction-to-fire tests - Heat release, smoke production, and mass loss rate
• ISO/TS 19700 - Controlled equivalence ratio method for the determination of hazardous components in fire effluents
• ISO 16702 - Workplace air quality - Determination of total organic isocyanates - Method using solvent extraction and HPLC analysis

Summary

Implementing ISO 29904:2013/Amd 1:2026 helps ensure that aerosol generation and measurement in fire chemistry is performed with updated terminology and recognized best practices. This amendment supports accuracy, clarity, and international consistency, making it essential for laboratories, regulatory bodies, industry professionals, and research institutions invested in fire safety and environmental standards.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out through
ISO technical committees. Each member body interested in a subject for which a technical committee
has been established has the right to be represented on that committee. International organizations,
governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely
with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are described
in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types
of ISO document should be noted. This document was drafted in a
