Full title and description

St ISO 23273-1:2006 — Fuel cell road vehicles — Safety specifications — Part 1: Vehicle functional safety. This part specifies essential functional-safety requirements for fuel-cell-powered road vehicles to address hazards to persons and the environment arising from the operational characteristics of the on-board fuel cell power system.

Abstract

ISO 23273-1:2006 defines requirements for vehicle functional safety covering both normal (fault-free) operation and single-fault conditions for fuel cell road vehicles. It focuses on hazards related to the fuel cell power system and excludes manufacturing, maintenance and repair. The standard applies when on-board working voltages are below specified limits (below 1000 V a.c. or 1500 V d.c.) in accordance with national or international rules.

General information

• ICS / categories: 43.120 (Electric road vehicles).
• Edition / version: Edition 1 (2006).
• Number of pages: 6 pages (as published by ISO).

Scope

Specifies essential functional-safety requirements for fuel cell road vehicles to mitigate hazards to people and the environment caused by the fuel cell power system. The standard addresses both normal operation and single-fault conditions and is limited to vehicles whose on-board electrical circuits do not exceed the stated maximum working voltages. It does not cover component-level protection, external power connection scenarios, or activities related to manufacturing, maintenance or repair.

Key topics and requirements

• Functional-safety requirements for fuel cell systems and associated vehicle functions.
• Consideration of normal (fault-free) operation and single-fault conditions.
• Voltage applicability limits: applies when on-board circuits are below specified maximum working voltages (below 1000 V a.c. or 1500 V d.c.).
• Exclusions for manufacturing, maintenance, repair and certain external-supply conditions.
• Requirements intended to protect persons and the environment from fuel-cell-related hazards.

Typical use and users

Used by vehicle manufacturers, vehicle safety and systems engineers, regulatory and homologation authorities, standards developers, and testing/inspection bodies involved in fuel cell vehicle design, validation and safety assessment.

Related standards

ISO 23273-1:2006 was published alongside other parts of the ISO 23273 series (for example Part 2 — protection against hydrogen hazards — and Part 3 — protection against electric shock, both originally published in 2006). The series was later consolidated and updated by ISO 23273:2013 (published in 2013), which superseded aspects of the earlier parts.

FAQ

Q: What is this standard?

A: ISO 23273-1:2006 is Part 1 of the ISO 23273 series, titled "Fuel cell road vehicles — Safety specifications — Part 1: Vehicle functional safety," providing essential functional-safety requirements for fuel cell road vehicles.

Q: What does it cover?

A: It covers functional-safety requirements to protect persons and the environment from hazards arising from the vehicle's fuel cell power system during normal operation and single-fault conditions, with stated voltage applicability limits; it does not cover manufacturing, maintenance or repair.

Q: Who typically uses it?

A: Vehicle manufacturers, systems and safety engineers, test laboratories, regulatory and homologation bodies, and standards committees working on fuel cell vehicle safety.

Q: Is it current or superseded?

A: ISO 23273-1:2006 has been withdrawn. Elements of the ISO 23273 series were reviewed and consolidated in ISO 23273:2013; users should consult the 2013 edition and any later updates for current requirements.
