What is BS EN ISO 29436-3:2019?

BS EN ISO 29436-3:2019 is a technical standard that provides guidelines for the measurement and characterization of airborne nanoobjects and their aggregates and agglomerates (NOAA) in workplace air samples. This standard is an important tool in assessing the potential risks associated with exposure to nanomaterials in various industries.

The Importance of Measuring NOAA

Nanomaterials are used in a wide range of industries, including electronics, healthcare, and energy. While these materials bring unique properties and benefits, they may also pose certain risks to human health and the environment. Measuring NOAA in workplace air samples helps identify and quantify the presence of nanomaterials, assess their potential risks, and develop effective control strategies.

Key Requirements of BS EN ISO 29436-3:2019

BS EN ISO 29436-3:2019 outlines specific requirements for sampling, sample preparation, and analysis of NOAA in workplace air samples. Some of the key requirements include:

Sampling: The standard provides guidance on selecting appropriate sampling devices and procedures to collect representative air samples.

Sample Preparation: It specifies methods for preparing samples, including dispersion techniques to separate NOAA from other particles.

Analysis: The standard defines analytical techniques for measuring and characterizing NOAA, such as electron microscopy and spectroscopy methods.

Benefits and Applications

BS EN ISO 29436-3:2019 offers several benefits and applications in the field of nanomaterial characterization. Firstly, it allows companies to comply with regulations and standards related to occupational safety and health. Secondly, it helps researchers and scientists in assessing the potential risks of nanomaterial exposure and developing appropriate control measures.

Additionally, this standard facilitates communication between different stakeholders, such as employers, employees, regulators, and researchers, by providing a common framework for nanoobject measurement and characterization. It also supports international harmonization of methods and promotes the exchange of information across industries and countries.
