What is the BS EN ISO 3696?

The Importance of BS EN ISO 3696

In the field of industry and manufacturing, standards play a crucial role in ensuring quality, safety, and efficiency. One such standard that holds significant importance is BS EN ISO 3696.

Understanding BS EN ISO 3696

BS EN ISO 3696 is the British adoption of the ISO 3696 standard which specifies the requirements for water used in laboratory applications. This international standard provides guidelines for the purity and classification of water intended for use in various scientific and analytical procedures.

Quality Considerations

According to BS EN ISO 3696, water for laboratory purposes is classified into different grades based on the level of impurities it contains. The four commonly recognized grades are: Grade 1, Grade 2, Grade 3, and Grade 4.

Grade 1 represents water of the highest purity, suitable for highly sensitive analytical techniques. This grade requires water to have low levels of impurities, such as conductivity, total organic carbon (TOC), and microbial contaminants.

Grade 2 is less pure compared to Grade 1 but still suitable for most laboratory applications. It allows slightly higher levels of impurities while still maintaining good quality.

Grade 3 is even less pure and is used for less critical laboratory procedures, where the presence of certain impurities does not affect the results significantly.

Grade 4 represents water that is of the lowest purity and is typically used for general cleaning and non-critical applications where water quality is less important.

Implementation and Compliance

Implementing and adhering to the BS EN ISO 3696 standard is crucial for laboratories to ensure the accuracy and reliability of their test results. It is essential to have appropriate water treatment systems in place, such as deionization or reverse osmosis, to achieve the required water purity levels.

Regular water quality testing and monitoring should also be performed to ensure ongoing compliance with the standard. This involves conducting periodic tests for parameters such as conductivity, pH, and microbial contamination.

In conclusion, BS EN ISO 3696 is a vital standard that provides guidelines for ensuring the quality and purity of water used in laboratory applications. Adhering to this standard allows laboratories to obtain accurate and reliable test results, ultimately contributing to the overall quality and integrity of scientific research and analysis.
