What is ISO/TS 5667-25 - Validation of the storage time of water samples about?
ISO/TS 5667-25 focuses on water quality. ISO/TS 5667-25 enables laboratories to study the stability of parameters when using the physico-chemical parameters measurement system: organic micropollutants, inorganic and organometallic micropollutants, nutrients and macropollutants in aqueous matrices (surface water, ground water, residual urban and industrial water and drinking water). It covers the sampling, transport and laboratory storage operations. Biological and microbiological methods are excluded.
It is necessary to have an analytical method with performances that have already been characterized (repeatability, intermediate precision, trueness, accuracy and uncertainty) in order to perform the stability study and implement its test plans.
Who is ISO/TS 5667-25 - Validation of the storage time of water samples for?
ISO/TS 5667-25 on validation of the storage time of water samples is relevant to:
- Chemical Engineers
- Researchers
- Quality control department
- Authorities and personnel responsible for water quality
Why should you use ISO/TS 5667-25 - Validation of the storage time of water samples?
Stability testing is an experiment in which samples of the formula are put at different environmental/ storage conditions for a set period of time to simulate what will happen to the product during its life cycle.
ISO/TS 5667-25 describes test plans and different operating methodologies of these test plans to define and verify the acceptable length of stability of a substance in a sample under specified conditions of preservation (temperature, matrix, light, addition of a stabilizer, where appropriate, type of preservation etc.) before starting analytical protocols (chemicals and physico-chemicals analysis).
ISO/TS 5667-25 addresses the need for harmonized and reliable data on stability, which is essential for the expression of recommendations for both normative and regulatory purposes.
With compliance and obedience to guidance under ISO/TS 5667-25, you can determine water quality so that it is safe for consumption.
