What is ISO 12917: 2015 and EN ISO 11681: 2016?

ISO 12917: 2015 and EN ISO 11681: 2016 are both international standards that provide guidelines for technical writing. Although they are similar in some aspects, they have distinct differences in their scope and purpose.

ISO 12917: 2015 is a standard for "Technical documentation — Format and structure of reports and articles". It specifies the format and structure of technical reports and articles, including the use of fonts, font sizes, and other visual elements. This standard is essential for ensuring that technical documents are organized and easily accessible to readers.

On the other hand, EN ISO 11681: 2016 is a standard for "Technical documentation — Content and structure of reports and articles". It provides guidelines for the preparation, execution, and evaluation of techniques for atmospheric dispersion modelling. This standard is particularly crucial in assessing the potential environmental impact of industrial activities and evaluating the release of pollutants into the environment.

The main purpose of EN ISO 11681: 2016 is to establish a consistent approach to atmospheric dispersion modelling, enabling organizations to accurately predict the dispersion of contaminants and evaluate their potential impact on the environment and human health.

Key Components of EN ISO 11681: 2016

EN ISO 11681: 2016 provides guidelines for the preparation, execution, and evaluation of atmospheric dispersion models. The standard defines the principles and procedures for conducting these assessments, enabling organizations to accurately predict the dispersion of contaminants and evaluate their potential impact on the environment and human health.

The standard has several key components, including:

Model validation: The standard provides guidelines for validating atmospheric dispersion models, ensuring that they are based on sound scientific principles and provide reliable results.

Dispersion assessment techniques: The standard defines various dispersion assessment techniques, such as the use of the wind rose diagram, the 1-D and 3-D wind rose diagrams, and the Modified-Dispersion-Model (MDM).

Evaluation of dispersion models: The standard outlines the criteria for evaluating the accuracy and reliability of dispersion models, including the use of statistical methods and the comparison with experimental data.

Documentation of dispersion models: The standard provides guidelines for documenting atmospheric dispersion models, including the use of standardized notation and the inclusion of relevant information.

Training on dispersion models: The standard recommends that organizations provide training on atmospheric dispersion models to ensure that their staff are familiar with the principles and procedures for preparing, executing, and evaluating dispersion models.

Conclusion

In conclusion, EN ISO 11681: 2016 is an essential standard for technical documentation that provides guidelines for the preparation, execution, and evaluation of atmospheric dispersion models. By following these guidelines, organizations can ensure that their technical documents are clear, coherent, and easily accessible to readers, leading to better product understanding and application.
