ISO/TS 9651:2025 - Nanotechnologies – Classification Framework for Graphene‐Related 2D Materials

Full Standard Title: Nanotechnologies – Classification Framework for Graphene‐Related 2D Materials

ISO/TS 9651:2025 establishes a comprehensive classification and reporting framework for graphene-related two-dimensional (2D) materials, targeting both sheet and particle forms. The technical specification details the essential characteristics required for commercial classification—such as layer count, lateral size, aspect ratios, and defect levels—and lays out standardized measurement protocols for consistent, reproducible assessment of material properties.

Aimed at commercial producers and end-users of graphene and derivative materials, the standard provides a template for unifying communication across markets, facilitating procurement, regulatory registration, and performance benchmarking. It enables stakeholders to differentiate products by independently validated properties rather than solely by supplier claims, thereby increasing transparency and confidence in supply chains.

Of particular note are the inclusion of technical data sheet templates and an explicit syntax for naming/material description, which empower organizations to generate, compare, and audit material specifications consistently on an international scale.

Key highlights:

• Specifies classification elements: material characteristics, measurement methods, allowable value ranges
• Details protocols for both sheet- and particle-form 2D materials: e.g. size, defect density, functionalization, crystallinity
• Includes a reporting framework and data sheet templates for commercial and regulatory applications

ISO 7899-3:2025 - Water Quality – Enumeration of Intestinal Enterococci – Part 3: Most Probable Number Method

Full Standard Title: Water Quality – Enumeration of Intestinal Enterococci – Part 3: Most Probable Number Method

ISO 7899-3:2025 introduces a standardized method for enumerating intestinal enterococci (including key Enterococcus species) in water samples, using the Most Probable Number (MPN) approach. This method supports the detection and quantification of faecal indicator bacteria in various water types—drinking water, bathing water (fresh or marine), and samples with high particulate content.

Based on the use of liquid growth media and statistical estimation tables, the standard enables detection at resolutions as low as 1 colony-forming unit (CFU) per 100 mL, and provides definitive results within a single working day (26 ± 2 hours). Results are interpreted via colorimetric detection of enzyme activity, ensuring a confirmed result without confirmatory subculturing in most routine use cases.

ISO 7899-3:2025 plays a crucial regulatory role in public health protection and water quality monitoring. Laboratories involved in water quality testing—including environmental agencies, municipal utilities, and private firms—will find its adoption essential for demonstrating compliance with both international and national water safety directives.

Key highlights:

• Defines application to a wide variety of water samples: drinking, fresh, and marine bathing water
• Enables rapid, sensitive detection of intestinal enterococci (down to 1 CFU/100 mL)
