FprEN IEC 62933-5-2:2025 – Safety Requirements for Grid-Integrated Electrochemical Energy Storage Systems

Electrical energy storage (EES) systems – Part 5-2: Safety requirements for grid-integrated EES systems – Electrochemical-based systems

This standard (FprEN IEC 62933-5-2:2025) addresses the system-wide safety challenges that arise as grid-connected electrochemical energy storage (notably battery energy storage systems or BESS) become more widespread. Covering the entire lifecycle from design to end-of-life, it innovates beyond previous component-centric standards to include:

• Risk assessment and mitigation strategies at the system and site level
• Interaction risks among subsystems (batteries, converters, controls) under both normal and abnormal conditions
• Safety design requirements for electrical, mechanical, thermal, chemical, and fire/explosion hazards

Organizations involved in designing, operating, maintaining, or procuring battery energy storage systems will find the guidance invaluable. The document emphasizes user safety, neighborhood protection, lifecycle management (including end-of-life), and formalizes communication of safety information to various stakeholders.

A key advancement is the inclusion of validation, testing, and risk analysis methodologies, with dedicated annexes for ownership models, hazard profiles (lithium-ion, lead-acid, flow, sodium, and more), fire testing, maintenance protocols, and signage. Further, it supports harmonized training and operational documentation to ensure that cutting-edge battery technologies do not outpace their risk management frameworks.

Key audiences: Energy utilities, system integrators, large-scale industrial users, and facility managers.

Key highlights:

• Lifecycle safety from design, through normal operation, to end-of-life
• Techniques for system-level risk assessment and mitigation, including fire and chemical hazards
• Requirements for testing protocols, incident handling, and staff training

ISO 11352:2025 – Water Quality: Estimation of Measurement Uncertainty in Analytical Methods

Water quality – Estimation of measurement uncertainty based on validation and quality control data

ISO 11352:2025 presents detailed, practical procedures to estimate measurement uncertainty for chemical and physicochemical laboratory methods—initially focused on water analysis but applicable to other chemical analyses. In this revision, the standard aligns uncertainty estimation with international metrology best practices, with procedures that rely on both validation and ongoing quality control data.

The document covers:

• Statistical frameworks for evaluating within-laboratory reproducibility and bias
• Calculation and reporting of combined and expanded uncertainty (in line with ISO/IEC Guide 98-3)
• Distinct requirements for validation (first-time) and quality control (ongoing) uncertainty estimation
• Comprehensive examples and annexes that make the statistical approach accessible to practitioners

Notably, it raises the bar for the minimum number of replicates in validation (from 8 to 20), introduces new guidance for analyzing control chart data, and refines calculations by promoting the use of pooled standard deviation. Laboratories can thus ensure their data meet the transparency and traceability expectations set by regulators and stakeholders, which is particularly critical in environmental compliance and reporting.

Main users: Laboratory managers, analysts, data quality professionals, and anyone responsible for analytical method validation.

Key highlights:

• Practical protocols for quantifying method performance uncertainty
• Enhanced requirements for reproducibility and bias documentation
• Guidance applicable beyond water, to all routine chemical analyses
