About this event

A live 30-minute expert session on Scoping and Pricing a SIL Verification Engagement (FSA & Services — Assessment & Services). What We'll Cover: What a SIL verification engagement covers and where it sits between SRS and validation in the client lifecycle Step by step: count SIFs, agree the failure-data source, pick the calculation method, and set review cycles into the quote How the engagement maps to IEC 61511 Clause 11.9 and the SIL verification report it must produce Common mistakes: quoting before seeing data quality, scope creep into SRS rewriting, no assumption register Evidence the client's auditor will need: calculation inputs, tool version, assumptions, and per-SIF results Related topics: sil verification scope · consulting proposal · pfd calculation · failure rate data · sif cou

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.
