Full title and description

ISO 10980:1995 — Validation of the strength of reference solutions used for measuring concentrations. This international standard gives practical procedures for preparing and checking the strength (concentration) of reference solutions used in analytical measurements, with an emphasis on methods that are straightforward for routine laboratory application.

Abstract

Provides procedures for preparing reference solutions and for verifying and ensuring the quality and degree of accuracy of the stated solution strength. The document is intended as a working tool for analytical chemists and laboratory staff; to remain practical it does not present the full underlying statistical theory but focuses on application-level checks, documentation and acceptance criteria for solution strengths.

Scope

ISO 10980:1995 specifies practical procedures to prepare reference solutions and to validate the declared strength (concentration) of those solutions for use in concentration measurements. It covers the laboratory checks, documentation and quality controls necessary to demonstrate that a prepared solution meets its intended concentration within stated limits. The standard is aimed at routine analytical work rather than at presenting full theoretical derivations of statistical techniques.

Key topics and requirements

• Guidance on preparation of reference solutions (materials, solvents, dilution techniques).
• Procedures for verification of solution strength (comparison with certified values, standardization methods).
• Quality controls: homogeneity, stability checks and storage/handling recommendations.
• Documentation and lab records required to demonstrate traceability and declared concentration.
• Practical acceptance criteria and simple approaches to assess uncertainty or agreement without lengthy statistical derivations.

Typical use and users

Used by analytical chemistry laboratories, quality control units in pharmaceutical, food and environmental testing, reference‑material producers and calibration laboratories to prepare, check and document reference solutions for routine concentration measurements. Typical users include bench chemists, laboratory managers, method developers and personnel responsible for measurement traceability and QC.

Related standards

Relevant complementary documents and standards include standards on competence and production of reference materials and laboratory competence (for example ISO 17034, which covers competence of reference material producers, and ISO/IEC 17025, which covers competence of testing and calibration laboratories). Guidance on certificates and labels for reference materials (ISO guides) is also relevant when documenting solution strengths and assigned values.

FAQ

Q: What is this standard?

A: ISO 10980:1995 is an ISO international standard that gives practical procedures for validating the strength (concentration) of reference solutions used in analytical measurements.

Q: What does it cover?

A: It covers preparation and verification procedures, quality checks (homogeneity and stability), documentation and practical acceptance criteria so that laboratories can demonstrate that a prepared solution meets its declared concentration for routine use.

Q: Who typically uses it?

A: Analytical chemists, QC and calibration laboratories, reference‑material producers and other laboratory personnel involved in preparing or using calibration/reference solutions in pharmaceutical, food, environmental and industrial testing.

Q: Is it current or superseded?

A: The 1995 edition (Edition 1) was published in August 1995 and, according to ISO records, was reviewed and confirmed (most recently in 2022) and therefore remains a current published International Standard in its original form.

Q: Is it part of a series?

A: It is a standalone ISO standard addressing validation of solution strength but is commonly used alongside related guides and standards on reference materials and laboratory competence (for example ISO 17034 and ISO/IEC 17025) to provide a complete quality and traceability framework.

Q: What are the key keywords?

A: Reference solution, validation, concentration, solution strength, reference material, traceability, homogeneity, stability, laboratory QC, documentation.
