What is ISO/TR 21386-Considerations for the measurement of nano-objects and their aggregates and agglomerates (NOAA) about?
ISO/TR 21386 discusses nanotechnologies. ISO/TR 21386 is an international standard that provides for the measurement of nano-objects and their aggregates and agglomerates (NOAA) in environmental matrices.
ISO/TR 21386 provides some considerations for the collection of environmental samples to be analyzed for manufactured NOAA, considerations to distinguish manufactured NOAA from background levels of naturally occurring nanoscale particles of the same composition, and preparation procedures to aid in the quantification of manufactured NM in environmental matrices.
ISO/TR 21386 assists with insights that require unique collection and analytical techniques specific to the composition of the particle. In addition, provides a review of published studies that report levels of NOAA in the environment and aspects of collection and sample preparation.
Who is ISO/TR 21386- Considerations for the measurement of (NOAA) for?
ISO/TR 21386 on nano-objects and their aggregates and agglomerates (NOAA) in environmental matrices is relevant to:
- Nanotechnology manufacturers
- Test centers for nanotechnology
- Regulatory authorities
Why should you use ISO/TR 21386- Considerations for the measurement of (NOAA)?
There is an interest in determining the concentration of nano-objects and their aggregates and agglomerates (NOAA) in environmental matrices. Manufactured nanomaterials (NM) enter the environment via release from the manufacturing process and its waste streams, as well as via the use of commercial products and their recycle and disposal streams. Such measurement efforts require an understanding of the occurrence of natural materials that can interfere with the analysis or skew the results.
ISO/TR 21386 guideline assists you with considerations for sampling and analyzing NOAA in air, for sampling and analyzing NOAA in surface water, for sampling and analyzing NOAA in seawater, for sampling and analyzing NOAA in sediment, and for sampling and analyzing NOAA in soil for the measurement of nano-objects and their aggregates and agglomerates (NOAA) in environmental matrices. This assists in proper data collection and sample preparation for the measurement of nano-objects and their aggregates and agglomerates (NOAA) in environmental matrices.
By adopting ISO/TR 21386 the user can ensure efficient measurement of NOAA in environmental matrices.
