Overview

SIST EN 27201-1:1997, based on ISO 7201-1:1989, establishes the specifications for two commonly used fire extinguishing media: halon 1211 (bromochlorodifluoromethane) and halon 1301 (bromotrifluoromethane). Issued by the Slovenian Institute for Standardization (SIST), this standard is part of a broader effort to ensure the quality and reliability of halogenated hydrocarbons used in fire protection applications.

The standard details the requirements for purity, acceptable levels of impurities, and guidelines for sampling and testing these chemical agents. It is intended for manufacturers, suppliers, and testing laboratories to verify the conformity of these agents prior to their use in fire extinguishing equipment. It does not cover the operational use or installation requirements for fire suppression systems - these are the subject of other standards.

Key Topics

• Product Specifications: Defines stringent criteria for halon 1211 and halon 1301, including purity thresholds, limits of acidity, water content, non-volatile residues, absence of halogen ions, and visual clarity.
• Testing and Sampling Methods: Prescribes standardized procedures to ensure consistent sample collection and laboratory testing, referencing established ISO methods.
• Packaging and Labelling: Outlines required information for safe handling, storage, and tracking, including supplier details, product identification, and relevant safety precautions.
• Physical Properties Overview: Provides informative data on characteristics like molecular mass, boiling and freezing points, and electrical conductivity, relevant for understanding performance in fire situations.
• Halons in Fire Suppression: Describes the essential role of halons due to their efficiency in extinguishing fires, including those involving electrical equipment, thanks to their low electrical conductivity.

Applications

Halon 1211 and Halon 1301 are extensively used as fire extinguishing media in multiple environments where rapid, effective fire suppression is critical and where minimal collateral damage is desired. Common applications include:

• Portable Fire Extinguishers: Especially valuable in high-risk operational settings such as server rooms, aircraft, and critical control centers.
• Fixed Automatic Fire Suppression Systems: Used in data centers, telecommunications installations, museums, and archives where sensitive materials or equipment require non-damaging fire protection.
• Electrical Equipment Fires: Due to low electrical conductivity, suitable for use on energized systems and complex machinery.

By adhering to SIST EN 27201-1:1997, organizations can ensure that the halons used meet internationally recognized requirements, aiding legal compliance and system effectiveness.

Related Standards

For comprehensive fire protection, refer also to:

• ISO 3363: Fluorochlorinated hydrocarbons for industrial use - Determination of acidity.
• ISO 3427: Gaseous halogenated hydrocarbons - Sampling procedures.
• ISO 5789: Fluorinated hydrocarbons for industrial use - Determination of non-volatile residue.

Other parts of the ISO 7201 series, as well as standards related to fire suppression system design, installation, and maintenance, provide additional requirements for using and handling halogenated fire extinguishing agents.

IS0 7201-1 : 1989 (E) Foreword IS0 (the International Organization for Standardization) is a worldwide federation of national standards bodies (IS0 member bodies). The work of pwparing International Standards is normally carried out through IS0 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, govern- mental and non-governmental, in liaison with ISO, also take part in the work. IS0 collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. Draft International Standards adopted by the technical committees are circulated to the member bodies for approval before their acceptance as International Standards by the IS0 Council. They are approved in accordance with IS0 procedures requiring at least 75 % approval by the member bodies voting. International Standard IS0 7201-1 was prepared by Technical Committee ISO/TC 21, Equipment for fire protection and fire fighting. This second edition cancels and replaces the first edition (IS0 7201 : 19821, which has been technically revised. At present, IS0 7201 consists of the following part, under the general title Fireprotec- tion - Fire extinguishing media - Halogenated hydrocarbons : - Part 1: Specifications for halon 1211 and halon 1301 Annex A of this part of IS0 7201 is for information only.

IS0 7201-1 : 1989 (E) Introduction This International Standard is one of a series giving specifications for fire extinguishing media in common use and which are in need of standardization for fire fighting pur- poses. These specifications are designed to establish that the medium in question has at least a minimum useful fire extinguishing capability and can therefore be reasonably sold for fire extinguishing purposes. Requirements for media used in particular equipment will form the subject of future International Standards. . 111 SIST EN 27201-1:1997
