Detailed Standards Coverage

prEN 50742:2025 - Safety of Machinery: Protection Against Corruption

Safety of machinery - Protection against corruption

prEN 50742:2025 is a groundbreaking European standard addressing one of the most pressing challenges in modern machinery: preventing both accidental and intentional (including malicious) corruption. Its requirements extend beyond traditional safety measures to consider actions by third parties that could compromise machine safety via manipulation of hardware, software, or data.

This standard applies to any hardware components (including remote interfaces and control systems) capable of transmitting signals or data, and to any software and data integral to the safe operation of machinery. Organizations must adopt either “Approach A” (for equipment not designed with cyber-guidance from the EN IEC 62443 series) or “Approach B” (leveraging compliance with the EN IEC 62443 standard family for industrial cybersecurity).

Major requirements include:

• Risk identification through comprehensive assessment per EN ISO 12100
• Countermeasures for vulnerabilities, including logging, evidence collection, access control, and cryptographic mechanisms
• Lifecycle coverage: from development through operation to decommissioning
• Specific focus on interfaces, software version control, and documentation of changes

Who must comply? Manufacturers, designers, control system integrators, and those specifying, designing, or validating machine safety systems. Any organization connecting machines via networks, Wi-Fi, or remote devices must rigorously apply these guidelines.

Practical implications: Adoption means enhanced protection against cyber-physical attacks, improved traceability for interventions, and robust evidence collection in case of incidents. A clear timeline for adoption is provided in the European context, with national implementation expected within twelve months and legacy systems grandfathered before publication.

Key highlights:

• Addresses lifecycle risks—development, manufacturing, operation, decommissioning
• Dual compliance paths (traditional safety or cyber-integrated design)
• Emphasizes cryptographic controls and detailed intervention logging

ISO 23693-2:2026 - Resistance to Gas Explosions: Passive Fire Protection Materials (Divisional Substrates)

Determination of the resistance to gas explosions of passive fire protection materials — Part 2: Divisional substrates

ISO 23693-2:2026 introduces sophisticated methodologies for pressure load simulation and mechanical testing to assess the ability of passive fire protection (PFP) materials and systems applied to panels and divisional elements to withstand explosion overpressures from events like gas leaks or dust explosions.

Key requirements include:

• Test design and specimen construction (minimum panel dimensions, support methods)
• Measurement protocols using calibrated pressure transducers and high-speed data acquisition
• Defined damage assessment (elastic vs. plastic response) and acceptance criteria
• Detailed reporting covering setup, results, and validity of each test

Who must comply? Fire safety engineers, manufacturers and suppliers of passive fire protection materials, building engineering consultants, and facilities managers for environments exposed to explosive atmospheres (e.g., petrochemical plants, industrial facilities, offshore platforms).

Practical implications: Complying with ISO 23693-2 ensures validated, repeatable testing of PFP systems under real-world explosion conditions, improving fire safety integrity, supporting product certification, and aligning with performance-based building codes.

Key highlights:

• Full-scale and representative specimen testing for field-relevant results
• Stringent pressure and displacement monitoring for comprehensive assessment
• Enhanced reproducibility and data quality in explosion resistance tests

ISO 27914:2026 - Carbon Dioxide Capture, Transportation, and Storage: Geological Storage

Carbon dioxide capture, transportation and storage — Geological storage

ISO 27914:2026 is a second edition consolidating best practices for the safe and sustainable geological storage of CO₂ streams, crucial for carbon capture and storage (CCS) projects worldwide. This document stipulates rigorous criteria for risk management, integrated project oversight, technical assessment, operational performance, and regulatory compliance across both onshore and offshore storage sites.

Main requirements involve:

• Comprehensive site identification, screening, and feasibility studies
• Multidisciplinary site characterization (geological, geomechanical, hydrogeological, and geophysical analyses)
• Design, construction, and monitoring of storage operations, including well design and abandonment
• Quantification methodologies for net CO₂ storage mass and long-term project integrity
• Integrated risk management plans and documentation throughout the project lifecycle

Who must comply? Energy project developers, environmental engineers, government regulators, CCS industry leaders, and researchers engaged in greenhouse gas mitigation infrastructure projects.

Practical implications: Executing ISO 27914-compliant CCS projects helps minimize risk of storage loss, supports due diligence for license applications, aligns with global climate goals, and assures investors, regulatory authorities, and communities of operational robustness.

Key highlights:

• Applies to both onshore and offshore geological strata (excluding CO₂-EOR and temporary tank storage)
• Focus on lifecycle management (project development through post-injection)
• Structured methodology for transparent risk documentation and stakeholder communication
