Overview
ISO 14451-4:2013 is an international standard published by the International Organization for Standardization (ISO) that specifies the requirements and categorization for micro gas generators used in vehicle pyrotechnic articles. This part of the ISO 14451 series defines the types and sequences of tests to assess micro gas generators, including acceptance criteria and classification rules. It applies primarily to type testing of micro gas generators and excludes articles containing military explosives or commercial blasting agents, except for black powder or flash composition.
This standard plays a crucial role in ensuring the safety, reliability, and performance of micro gas generators used in passive safety systems such as airbags and seatbelt pretensioners in automotive applications.
Key Topics
Scope and Applicability
ISO 14451-4:2013 focuses on micro gas generators for vehicles, detailing the necessary tests for their mechanical, thermal, and electrostatic robustness.Test Procedures and Acceptance Criteria
The standard specifies a structured test matrix including the following essential evaluations:- Design and Documentation Verification: Ensuring complete and accurate technical documentation.
- Drop Test: Confirming no unintended ignition or leakage on impact.
- Temperature and Vibration Resistance Test: Assessing performance under extreme environmental conditions without accidental triggering.
- Temperature and Humidity Cycling Test: Evaluating durability through climatic stress.
- Electrostatic Discharge Test: Verifying immunity to static electricity to prevent unintentional actuation.
- Reservoir Test: Examining containment integrity and expected failure modes.
- Functional Operation Test: Confirming performance and expected operation under non-fixed conditions.
Categorization of Micro Gas Generators
The standard classifies generators into two categories based on risk levels during operation:- Category P1: Low-risk micro gas generators with fragment impact distances up to 15 meters.
- Category P2: Higher-risk devices intended for handling by qualified personnel only.
Test Matrix
ISO 14451-4 includes a detailed matrix specifying the test sequence and sample handling protocols, optimizing test efficiency and reliability of evaluation.
Applications
ISO 14451-4:2013 is primarily applied in:

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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International
Standards adopted by the technical committees are circulated to the member bodies for voting.
Publication as an International Standard requires approval by at least 75 % of the member bodies
casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

Avant-propos
L’ISO (Organisation internationale de normalisation) est une fédération mondiale d’organismes
nationaux de normalisation (comités membres de l’ISO). L’élaboration des Normes internationales est
en général confiée aux comités techniques de l’ISO. Chaque comité membre intéressé par une étude
a le droit de faire partie du comité technique créé à cet effet. Les organisations internationales,
gouvernementales et non gouvernementales, en liaison avec l’ISO participent également aux travaux.
L’ISO collabore étroitement avec la Commission électrotechnique internationale (CEI) en ce qui concerne
la normalisation électrotechnique.
Les Normes internationales sont rédigées conformément aux règles données dans les Directives
ISO/CEI, Partie 2.
La tâche principale des comités techniques est d’élaborer les Normes internationales. Les projets de
Normes internationales adoptés par les comités techniques sont soumis aux comités membres pour vote.
Leur publication comme Normes internationales requiert l’approbation de 75 % au moins des comités
membres votants.
