EN ISO 24181-1:2025 – Determination of Non-Rare Earth Impurities in Rare Earth Metals

Rare earth – Determination of non-rare earth impurities in individual rare earth metals and their oxides – ICP-AES – Part 1: Analysis of Al, Ca, Mg, Fe and Si (ISO 24181-1:2024)

EN ISO 24181-1:2025 defines rigorous analytical procedures for the detection and quantification of non-rare earth impurities—including magnesium (Mg), aluminum (Al), silicon (Si), calcium (Ca), and iron (Fe)—in rare earth metals and their oxides. Utilizing inductively coupled plasma atomic emission spectroscopy (ICP-AES), this standard establishes precise measurement ranges: mass fractions of 0.001 to 0.2% for Mg, Al, Si, Ca, and 0.001 to 0.5% for Fe.

The standard is crucial for manufacturers, laboratories, and trading entities engaged in the production and quality control of rare earth materials. By harmonizing analytical methodologies, it minimizes inconsistencies and enhances comparability of results across borders. Implementation reduces risks of costly production errors and downstream performance failures in high-tech applications such as electronics, magnets, and green technologies.

Key highlights:

• Specifies exact measurement protocols for primary non-rare earth impurities
• Ensures analytical consistency using ICP-AES with verified ranges
• Supports compliance for quality-sensitive industries including electronics, automotive, and renewable energy

ISO 9241-161:2025 – Ergonomics of Human-System Interaction: Visual User-Interface Elements

Ergonomics of human-system interaction – Part 161: Visual user-interface elements

ISO 9241-161:2025 delivers robust guidelines for the selection, usage, and interdependency of visual user-interface (UI) elements in interactive systems. The scope encompasses visual software components across desktop, portable, mobile, and cross-device systems. It offers requirements and recommendations to improve usability, accessibility, and overall user experience, without prescribing graphical or interaction techniques specific to device types.

This standard is indispensable for user interface designers, human factors engineers, system integrators, and procurement professionals developing or sourcing software applications for occupational environments. By adhering to these guidelines, organizations can reduce error rates, support inclusive design, and ensure compliance with international ergonomics best practices.

Key highlights:

• Provides definitions and compositional rules for mainstream UI elements (e.g., buttons, sliders, accordions)
• Addresses accessibility and consistent user experience across platforms
• Excludes purely decorative and aesthetic components to focus on functional usability

IEC 62933-5-2:2025 – Safety for Grid-Integrated Electrical Energy Storage Systems

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

IEC 62933-5-2:2025 is a milestone for the secure deployment of grid-connected battery energy storage systems (BESS). The standard details safety aspects relevant both to human health and the operational environment, extending across the full lifecycle (design, commissioning, operation, end-of-life) of BESS using electrochemical technologies such as lithium-ion, lead-acid, and emerging battery chemistries.

Organizations deploying BESS for renewable integration, grid stability, or industrial backup will be required to comply. The standard sets forth system-level risk assessments, hazard identification, prevention and mitigation measures, and outlines maintenance, shutdown, and end-of-life practices. Notably, it distinguishes safety provisions that apply due to subsystem interactions and introduces clear validation and testing requirements.

Key highlights:

• Addresses fire, electrical, chemical, and mechanical hazards unique to BESS
• Mandates comprehensive system validation and operator/user safety information
• Life cycle safety management including design revisions and end-of-life procedures

ISO 20468-10:2025 – Guidelines for Dependability of Water Reuse Treatment Technologies

Performance evaluation of treatment technologies for water reuse systems – Part 10: Guidelines for evaluation of dependability of treatment systems

ISO 20468-10:2025 introduces comprehensive methodologies for evaluating the dependability of water treatment systems, a metric defined by system availability, reliability, maintainability, and support performance. Applicable to all stages of water reuse system lifecycle, it provides both qualitative and quantitative assessment tools—including critical performance control point (PCP) analysis, benchmarking strategies, and maintenance-centric evaluation protocols.

Utilities, municipalities, industrial water managers, and technology suppliers will find the guidance essential for consistent performance, risk reduction, and regulatory alignment with sustainability requirements. Integration of this standard supports selection, operation, and maintenance of advanced water reuse systems, reducing downtime and ensuring continuous compliance.
