BS EN ISO 5667-3:1996 is a British Standard that has been adopted as a European Standard and an International Standard. Its full title is "Water quality - Sampling - Part 3: Guidance on the preservation and handling of samples." This standard provides guidelines and recommendations for the proper preservation and handling of water samples in order to ensure accurate and reliable water quality analysis.
The standard is intended to be used by professionals involved in water quality monitoring, environmental testing, and related fields. Proper preservation and handling of water samples are crucial to maintain the integrity of the samples and prevent potential degradation or contamination that could lead to inaccurate test results.
The key areas covered by BS EN ISO 5667-3:1996 include:
Selection of Containers: The standard provides guidance on selecting appropriate containers for collecting and storing water samples. The choice of container material is important to avoid interactions between the container and the sample.
Preservation Techniques: Different water parameters can change over time due to various chemical and biological reactions. The standard offers advice on using various preservation techniques, such as adding chemicals to stabilize the sample or maintaining specific temperature conditions.
Sample Handling: Proper handling of samples is crucial to prevent contamination or alteration of the sample characteristics. The standard offers recommendations on procedures for sample collection, transportation, storage, and analysis.
Documentation: Clear documentation of the sampling and preservation procedures is essential to ensure traceability and transparency in the testing process. The standard provides guidance on record-keeping practices.
Quality Control: Ensuring the accuracy and reliability of water quality measurements is important. The standard outlines quality control measures to be implemented during the sampling and analysis processes.
It's important to note that this standard was published in 1996, and while its fundamental principles remain relevant, there might have been updates, revisions, or newer standards that have been published since then. If you are working with water quality sampling, it's advisable to consult the latest version of relevant standards or guidelines to ensure that your practices are up to date and in line with the latest scientific knowledge and industry best practices.
