Safety of machinery — Safety-related parts of control systems — Part 3: Markov model-based PFH calculation

Machine safety depends on accurately assessing the probability of dangerous failures. This technical report delivers an advanced, Markov model-based approach to estimate the mean probability of failure per hour (PFH) for safety system architectures, supplementing ISO 13849-1.

What sets it apart:

• Markov models are used to derive equations for both single- and two-channel safety architectures
• Explicit consideration of diagnostic coverage, mission times, common cause failures, and component wear
• Alternative to table-based and basic formula approaches, increasing calculation transparency and flexibility
• Includes detailed definitions of all system parameters, test procedures, and worked examples

Targeted at machinery designers, functional safety engineers, system integrators, and risk assessors, adoption of this standard enables much finer control over safety risk assessment and compliance with international regulations.

This standard updates practices for quantifying safety integrity via probabilistic methods, directly supporting regulatory and customer requirements for machine-related safety.

Key highlights:

• Supports both simple and complex machine control architectures
• Allows for custom mission times, repair rates, and diagnostic capabilities
• Enhances system-specific reliability calculations, especially for high-integrity applications

ISO/TS 23099:2026 - Large Yachts — A Methodologic Framework to Assess Large Yachts (30m+) on Their Environmental Performance and Credentials

Large yachts — A methodologic framework to assess large yachts (30m+) on their environmental performance and credentials

This innovative ISO technical specification introduces a robust, data-driven methodology to assess and compare the environmental impact of large yachts (30m+). It allows direct benchmarking of operational energy use and emissions against a standardized baseline fleet, supporting green certification and transparent reporting.

Technical specifics include:

• Detailed operational profile modeling (year-round, transoceanic capability, professionally crewed)
