Overview

CEN ISO/TS 19807-1:2022 (adopted from ISO/TS 19807-1:2019) is a technical specification for nanotechnologies - magnetic nanomaterials - Part 1: specification of characteristics and measurements for magnetic nanosuspensions. It defines the characteristics of magnetic nanosuspensions that should be measured, lists measurement methods, provides terms and symbols, and sets out reporting elements. This is a generic, application‑neutral document intended to harmonize definitions and test approaches for magnetic nanosuspensions across industry and research.

Key topics and requirements

Scope and purpose: Specifies which suspension characteristics to measure and recommends measurement methods; does not address specific applications.

Terms and definitions: Standardizes terminology such as agglomerate, aggregate, core‑shell nanoparticle, hydrodynamic diameter, dispersant, and dispersing medium (see extracted clauses).

Magnetic properties: Defines magnetic measurement concepts including AC susceptibility, differential magnetic susceptibility, magnetic moment, and Curie temperature, and notes dependence on frequency and temperature.

Physical and chemical characteristics: Includes descriptors such as chemical composition, dry matter content, dynamic viscosity, fluid density, freezing point, and equivalent diameter.

Measurement methods: Lists appropriate methods for quantifying the above characteristics (the specification references methods rather than prescribing a single technique).

Reporting requirements: Guidance on what metadata and measurement conditions to report (temperature, excitation frequency/amplitude, material constants, etc.).

Informative annex: Annex A describes components of liquid suspensions (magnetic nanoparticles, dispersing medium, dispersant).

Normative status: No normative references; intended for provisional application as a CEN Technical Specification.

Applications and who uses it

This specification is useful to organizations and professionals working with magnetic nanosuspensions:

R&D and academic labs developing magnetic nanoparticle formulations.

Manufacturers producing magnetic inks, ferrofluids, lubricants, coolants, dampers, and magnetic soaps.

Medical and biotech developers working on magnetic resonance contrast agents, drug‑delivery carriers, and magnetic hyperthermia.

Environmental technology firms using magnetic nanosuspensions for remediation.

Testing and calibration laboratories and quality‑assurance teams needing harmonized measurement and reporting practices.

Regulators and standards bodies seeking consistent characterization data for compliance and comparison.
