ISO 26262

From Wikipedia, the free encyclopedia

ISO 26262 is a Functional Safety standard, titled "Road vehicles – Functional safety".

Functional safety features form an integral part of each product development phase, ranging from the specification, to design, implementation, integration, verification, validation, and production release. The standard ISO 26262 is an adaptation of the Functional Safety standard IEC 61508 for Automotive Electric/Electronic Systems. ISO 26262 defines functional safety for automotive equipment applicable throughout the lifecycle of all automotive electronic and electrical safety-related systems.

The first edition, published on 11 November 2011, is intended to be applied to electrical and/or electronic systems installed in "series production passenger cars" with a maximum gross weight of 3500kg. It aims to address possible hazards caused by the malfunctioning behaviour of electronic and electrical systems.

The standard consists of 9 normative parts and a guideline for the ISO 26262 as the 10th part.

Like its parent standard IEC 61508, ISO 26262 is risk based safety standard, where the risk of hazardous operational situations are qualitatively assessed and safety measures are defined to avoid or control systematic failures and to detect or control random hardware failures, or mitigate their effects.

  • Provides an automotive safety lifecycle (management, development, production, operation, service, decommissioning) and supports tailoring the necessary activities during these lifecycle phases.
  • Covers functional safety aspects of the entire development process (including such activities as requirements specification, design, implementation, integration, verification, validation, and configuration).
  • Provides an automotive-specific risk-based approach for determining risk classes (Automotive Safety Integrity Levels, ASILs).
  • Uses ASILs for specifying the item's necessary safety requirements for achieving an acceptable residual risk.
  • Provides requirements for validation and confirmation measures to ensure a sufficient and acceptable level of safety is being achieved.[1]

VDC Research reports that adherence to ISO 26262 and AUTOSAR is expected to increase significantly in the next two years.[2] Therefore, many functional safety service providers, such as kVA or SGS-TÜV, have created training programs to help understand the various safety processes as well as legal responsibilities and what is involved to achieve compliance.[3][4][5]

The ten parts of ISO 26262:

  1. Vocabulary
  2. Management of functional safety
  3. Concept phase
  4. Product development at the system level
  5. Product development at the hardware level
  6. Product development at the software level
  7. Production and operation
  8. Supporting processes
  9. Automotive Safety Integrity Level (ASIL)-oriented and safety-oriented analysis
  10. Guideline on ISO 26262
