As urbanization accelerates and regulatory expectations increase, international standards published in this field play a vital role in guiding best practices, safeguarding public health, and supporting compliance. This article examines pivotal standards published in January 2026, equipping professionals, quality managers, and compliance officers with detailed knowledge on:

• Decentralized water reuse system management
• Laboratory methods for chemical protective clothing
• Frameworks for soil ecosystem services
• Fire classification for safety equipment
• Quantifying and communicating product carbon footprints

By understanding these new standards, organizations can lead in safety, sustainability, and operational efficiency.

Detailed Standards Coverage

ISO 18998:2026 - Guidelines for Managing Decentralized Urban Water Reuse

Water reuse in urban areas — Guidelines for decentralized water reuse system — Management of a decentralized water reuse system

ISO 18998:2026 is essential for cities and urban developments aiming to adopt or optimize decentralized water reuse systems. The standard sets out comprehensive management models for all system components: source water, treatment, storage, distribution, end-uses, sludge management, and ongoing monitoring and maintenance. Rather than prescribing regulatory values or specific parameters, it focuses on robust management frameworks that ensure safety, reliability, and sustainability across onsite, cluster, and community models.

The guidance covers risk management, emergency response, and community engagement, ensuring systems are not only technically sound but also socially accepted and economically viable. The practical recommendations help utilities, facility managers, and municipal planners integrate decentralized water reuse into urban infrastructure, with emphasis on lifecycle management.

Key highlights:

• Complete management processes for each water reuse system component (treatment, storage, distribution, end-use)
• Risk management strategies, emergency planning, and legal compliance
• Flexible models adaptable to different urban contexts (onsite, cluster, community)

ISO 6529:2026 - Chemical Protective Clothing: Resistance to Liquid and Gas Permeation

Protective clothing — Protection against chemicals — Determination of resistance of protective clothing materials to permeation by liquids and gases

Addressing workplace safety in chemical industries, ISO 6529:2026 provides laboratory test methods for assessing the resistance of clothing materials—including gloves and footwear—to continuous contact with hazardous chemicals. The new release refines test methods for both liquid (Method A) and gaseous (Method B) chemicals, introducing stricter controls on volatility and solubility of challenge chemicals, and standardized approaches to normalization and pressure parameters. It guides on measuring key performance attributes—cumulative permeation, permeation rate, and breakthrough time—critical for selecting and certifying personal protective equipment (PPE).

This update is pivotal for manufacturers, laboratory managers, procurement specialists, and safety officers seeking to ensure compliance with the latest international safety requirements. Enhanced focus on material construction, seam resistance, and test reproducibility ensures that only demonstrably effective PPE makes it to end users.

Key highlights:

• Improved test precision for liquid and gas chemical permeation
• Material and seam performance assessment, pressure and normalization controls
• Updated test reporting and calibration procedures to support compliance

ISO/TS 18718:2026 - Soil Functions and Ecosystem Services: Definitions and Framework

Soil functions and related ecosystem services — Definitions, descriptions and conceptual framework

ISO/TS 18718:2026 establishes an international common ground for assessing and communicating the ecological functions of soils and their related ecosystem services. It defines core terms and analytical frameworks, bridging the gap between natural sciences and policy-driven ecosystem service evaluations. Covering functions such as water regulation, contamination retention, nutrient cycling, habitat provision, and climate regulation, the standard supports agricultural planners, soil scientists, environmental consultants, and land policymakers in harmonizing their assessments.

Practical for land management, remediation, and biodiversity initiatives, the standard improves transparency and comparability across national and international projects. It also underpins sustainable soil management policies and reporting for ecosystem health and resilience.

Key highlights:

• Fully-aligned terminology for soil functions and ecosystem service evaluation
• Framework links soil processes with ecosystem services for standardized reporting
• Supports policy, scientific comparison, and land management best practices

ISO 3941:2026 - Classification of Fires

Classification of fires

The latest edition of ISO 3941:2026 clarifies the internationally recognized system for classifying fires by fuel type. This classification forms the backbone of compatible fire protection equipment design and firefighting techniques. By precisely defining classes (such as Class A for ordinary combustibles, B for flammable liquids, C for gases, D for metals, F for cooking oils, and L for lithium), the standard ensures that firefighting solutions—extinguishers, alarms, system design—are properly selected and certified.

Facilities, fire safety engineers, emergency response teams, and product designers benefit from standardized fire classification, facilitating regulatory compliance, product harmonization, and improved safety outcomes worldwide.

Key highlights:

• Comprehensive fire class definitions by fuel type
• Foundation reference for firefighting equipment selection and system design
• Updated classification for new and emerging fuel risks (including lithium)

IEC 63372:2026 - Carbon Footprint & GHG Reductions in Electric and Electronic Systems

Quantification and communication of carbon footprint, GHG emission reductions and avoided emissions from electric and electronic products and systems - Principles, methodologies, requirements and guidance

IEC 63372:2026 breaks new ground by providing a standardized methodology for quantifying and communicating the carbon footprint, greenhouse gas (GHG) emission reductions, and avoided emissions associated with electric and electronic (EE) products and systems. Anchored in life cycle assessment (LCA), the standard details step-by-step procedures for calculating product-level footprints, establishing baselines, evaluating product-related GHG projects, and reporting results for organizational and regulatory transparency.

This standard is essential for electronics manufacturers, sustainability managers, project developers, and regulatory bodies pursuing net-zero strategies and credible climate claims. By aligning with enhanced scientific approaches, data quality requirements, scope definitions, and communication guidelines, it also supports compliance with emerging global GHG reporting frameworks and promotes transparent stakeholder disclosures.

Key highlights:

• Consistent LCA-based methodology for CFP and GHG quantification
• Guidance on avoided emissions, product GHG reductions, and robust reporting
• New content aligned with updated international GHG protocols and standards
