Full title and description

ISO/TR 13097:2013 — Guidelines for the characterization of dispersion stability. This Technical Report provides guidance for characterizing the stability of liquid dispersions (suspensions, emulsions, foams and mixtures thereof) to support product design, optimization, quality control and estimation of shelf life.

Abstract

ISO/TR 13097:2013 addresses how to define and measure the stability of liquid dispersions by tracking changes in physical properties over time. It explains when real-time monitoring or predictive (accelerated) testing is appropriate, and gives guidance for selecting measurements to rank, identify and quantify instability for applications such as formulation development, processing control and shelf‑life estimation.

Scope

This Technical Report gives guidance for the characterization of the stability of liquid dispersions (including suspensions, emulsions, foams and combinations). It defines stability in terms of changes in one or more measurable physical properties over a given time period, and provides recommendations on monitoring, accelerated testing, choice of measurement methods and how to use observed rates of change to estimate shelf life or rank formulations.

Key topics and requirements

• Definition of dispersion stability in operational terms (change in physical property over time).
• Guidance on selecting relevant measurements for stability (e.g., particle size distribution, visual observation/turbidity, rheological properties, sedimentation/creaming rates, and other appropriate physical parameters).
• Recommendations for monitoring strategies: real‑time measurement, accelerated aging and predictive approaches for very stable systems.
• Use of measurement results to rank, identify and quantify instability and to estimate shelf life based on observed rates of change.
• Contextual guidance for application areas such as product design, process control and quality assurance rather than prescriptive test methods.

Typical use and users

Applied by formulation scientists, R&D teams, quality control and analytical laboratories in industries that handle liquid dispersions (paints and coatings, pharmaceuticals, food and beverages, personal care, agrochemicals and specialty chemicals). Typical uses include selecting stability tests during development, comparing formulations, troubleshooting processing or storage instability, and supporting shelf‑life claims.

Related standards

ISO/TR 13097:2013 is produced by ISO/TC 24/SC 4 and sits alongside other particle and suspension characterization standards (particle‑size measurement methods, sedimentation and rheology standards, and nanomaterial characterization technical specifications). It is intended as guidance and should be used together with method standards appropriate to the chosen measurements.

FAQ

Q: What is this standard?

A: ISO/TR 13097:2013 is a Technical Report titled "Guidelines for the characterization of dispersion stability" that provides guidance on how to define, measure and interpret stability of liquid dispersions.

Q: What does it cover?

A: It covers concepts and practical guidance for stability characterization (suspensions, emulsions, foams and mixtures), including choice of measurements, monitoring vs accelerated testing, ranking and quantification of instability, and estimating shelf life from observed change rates. It is guidance rather than a prescriptive test method.

Q: Who typically uses it?

A: Formulation scientists, R&D and QC laboratories, standards committees and others working on product development, process control or shelf‑life assessment for products containing liquid dispersions.

Q: Is it current or superseded?

A: ISO's catalogue lists ISO/TR 13097 as published (Edition 1, 2013) and does not show a superseding document; therefore it remains the current Technical Report published in 2013 (publication date shown as 30 May 2013 / Edition 2013). Users should always check the ISO catalogue or national standards body for the latest status before relying on a standard. (Status checked against ISO catalogue and commercial standards listings.)

Q: Is it part of a series?

A: It is a stand‑alone Technical Report produced by ISO/TC 24/SC 4 and complements other ISO standards and technical specifications on particle characterization, measurement methods and related techniques; it is not a numbered multi‑part standard series itself.

Q: What are the key keywords?

A: Dispersion stability, emulsions, suspensions, foams, accelerated ageing, shelf life, particle size, sedimentation, turbidity, rheology.
