About this event

A live 30-minute expert session on Functional Insufficiencies vs Faults — Choosing 26262 or 8800 Treatment (ISO 8800 — Safety & Artificial Intelligence). What We'll Cover: What functional insufficiency means for AI elements and where the classification step sits in cross-standard safety planning The core method, step by step: sorting observed failure causes into fault, insufficiency, or triggering condition buckets How the split maps to ISO 26262 tailoring versus ISO 21448 extension inside ISO 8800, and the analysis records produced Common mistakes: forcing ML performance limitations into fault models where FMEA-style mitigations do not apply The classification rationale and cross-standard coverage argument an assessor expects for every failure cause Related topics: iso 8800 · iso pas 8800

About Functional Safety Foundations

This online session delivers expert-led instruction on the regulatory landscape and implementation approach for Functional Safety Foundations.

The cross-sector fundamentals underlying every functional safety standard: risk as severity × likelihood, the safety function concept, integrity levels, the safety lifecycle, and the split between random and systematic failures.

What it regulates

Shared vocabulary and reasoning: hazard → risk → risk reduction allocation → safety requirement → verified implementation → maintained integrity in operation.

Who must comply

Everyone entering the field — the conceptual base of the entire catalog.

Key requirements of Functional Safety Foundations

  • Hazard and risk fundamentals
  • Safety function anatomy: sensor-logic-actuator with defined safe state
  • Integrity ladders (SIL/PL/ASIL/DAL) as risk-reduction currencies
  • Random vs systematic failure treatment
  • Lifecycle and management of functional safety incl. competence

Key concepts: Functional Safety Foundations

Functional safety management
Planning, competence, documentation and assessment wrapped around technical work.
Random vs systematic
Hardware wear-out/chance failures quantified statistically versus design/process errors controlled by rigor.
Risk reduction allocation
Distributing required risk reduction among mechanical design, safeguards, control functions and procedures.
Safe state
The defined condition a function drives the equipment to on demand or fault.

Frequently asked questions: Functional Safety Foundations

Why can't testing alone prove safety?

Rare-event targets (like 1e-7/h) are unverifiable by test duration, and systematic errors evade random testing — hence the standards' dual machinery of quantified hardware analysis plus process rigor and independent assessment.
