Project Description

IATF 26262 Functional Safety Process Management Certifications

ISO 26262 is to address the sector specific needs of electrical and/or electronic (E/E) systems within road vehicles. It applies to all activities during the safety lifecycle of safety-related systems comprised of electrical, electronic and software components. In the standard, Functional Safety is defined as the “absence of unreasonable risk due to hazards caused by malfunctioning behavior of electrical/electronic systems”.
With the trend of increasing technological complexity, software content and mechatronic implementation, among others there are increasing risks from systematic failures and random hardware failures, these being considered within the scope of functional safety. ISO 26262 includes guidance to mitigate these risks by providing appropriate requirements and processes.
The achievement of functional safety is influenced by the development process, the production and service processes and the management processes. To achieve functional safety, ISO 26262:
  •  provides a reference for the automotive safety lifecycle and supports the tailoring of the activities to be performed during the lifecycle phases, i.e., development, production, operation, service, and decommissioning;
  • provides an automotive-specific risk-based approach to determine integrity levels [Automotive Safety Integrity Levels (ASIL)];
  • uses ASILs to specify which of the requirements of ISO 26262 are applicable to avoid unreasonable residual risk;
  • provides requirements for functional safety management, verification, validation and confirmation measures; and
  • provides requirements for relations with suppliers.

Since the original publication of ISO 26262:2011, as an adaptation of IEC 61508, on Nov 15, 2011, the industry has undergone several significant changes. The rapid deployment of Automated Driving connected technologies, together with the associated cybersecurity threat has seen growing inadequacies in the original iteration of ISO 26262. Accordingly, ISO 26262:2018, the second edition and update to the standard, is planned to publish in late-2018.

The courses will include ISO 26262 Application Training, ISO 26262 Professionals, etc。

Primary Changes to ISO 26262:2018 主要變更
  • Eliminates the weight limit, and will thereby expand its coverage to other vehicle categories, including heavier road cars, trucks, busses, and motorcycles.
  • Guidelines on the application of ISO 26262 to semiconductors in the standard’s new Part 11.
  • Updates to the PMHF (Probabilistic Metric for Hardware Failure) equation and verification of safety analysis.
  • Extend the process to ensure confidence in the use of software tools to include vendor validation

Scope of ISO 26262:2018 應用範圍

  • ISO 26262 is intended to be applied to safety-related systems that include one or more electrical and/or electronic (E/E) systems and that are installed in series production road vehicles, excluding mopeds.
  • Systems and their components released for production, or systems and their components already under development prior to the publication date of this edition of ISO 26262, are exempted from the scope of this edition.
  • ISO 26262 addresses possible hazards caused by malfunctioning behaviour of safety-related E/E systems, including interaction of these systems.
  • It does NOT address hazards related to electric shock, fire, smoke, heat, radiation, toxicity, flammability, reactivity, corrosion, release of energy and similar hazards, unless directly caused by malfunctioning behaviour of safety-related E/E systems.
  • ISO 26262 does NOT address the nominal performance of E/E systems, even if functional performance standards exist for these systems (e.g. active and passive safety systems, brake systems, adaptive cruise control).

Structure of ISO 26262:2018 結構

The below figure shows the overall structure of ISO 26262. ISO 26262 is based upon a V-model as a reference process model for the different phases of product development.
Note: The shaded “V”s represent the interconnection among ISO 26262-3, ISO 26262-4, ISO 26262-5, ISO 26262-6 and ISO 26262-7; for motorcycles ISO 26262-12, clauses 6 supplements ISO 26262-3 and clause 7, 8 and 9 supplements Part 4.

Safety Integrity Level (ASIL) 安全完整性等級

  • Functional safety experts identify and assess hazards (safety risks).
  • ASIL is determined by a risk analysis of a potential hazard by looking at risk parameters (Severity, Exposure and Controllability) of the vehicle operating scenario.
  • The ASIL levels – A, B, C, and D are assigned based on an allocation table defined by ISO 26262 standard.

Certification for Process Management

More and more automotive customers are requesting their suppliers to implement process management based on ISO 26262 standard. We will provide audit and certification for process management based on ISO 26262, including design and development and/or production processes.

Product test-based certification is a sector different from process management.

Benefits | 益處

  • Enjoys global acceptance of automotive manufacturers
  • Improves your overall competitive ability
  • Ensures uniform quality on a global scale
  • Creates transparency of processes
