What is BS EN 13205-5 - Airborne particle concentrations about?
BS EN 13205-5 specifies a method for determining the performance of an aerosol sampler under prescribed workplace conditions in order to test whether the performance of a candidate sampler fulfils the requirements of EN 13205-1.
BS EN 13205-5 is applicable to all samplers used for the health-related sampling of particles in workplace air. Different test procedures and types of evaluation are included to enable application of this part of EN 13205 to a wide variety of instruments.
The methods specified in BS EN 13205-5 are not applicable to tests where the performance of personal samplers is related to static samplers or vice versa.
Who is BS EN 13205-5- Airborne particle concentrations for?
BS EN 13205-5 on workplace exposure assessment of nano-objects is useful for:
- Manufacturers of nanomaterials
- Testing laboratories
- Human resources executives
- Occupational hygienist
- Health and safety personnel
- Other executives responsible for health and safety of employees
Why should you use BS EN 13205-5- Airborne particle concentrations?
The workplace performance test for samplers for the inhalable, thoracic or respirable aerosol fractions described in this document is based on a comparison of concentrations sampled from a specific workplace by a candidate sampler and a validated sampler.
BS EN 13205-5 provides methods and procedure for determining the aerosol sampler performance and sampler comparison carried out at workplaces.
BS EN 13205-5 specifies also a simple method to determine how, for a specific workplace aerosol, the concentration measured by the candidate sampler can be recalculated into that of a validated sampler.
BS EN 13205-5 provides method for calculating the expanded uncertainty for a measuring procedure based on sampling.
BS EN 13205-5 concerns the elements of exposure assessment and provides guidance for various applications. BS EN 13205-5 provides guidance on the use of commonly used devices for the detection of airborne particle concentrations in the workplace air.
What’s changed since the last update?
BS EN 13205-5:2014 supersedes BS EN 13205-5:2001, which is withdrawn. The main changes with respect to the previous edition are listed below:
- This part of EN 13205 is partly based on Annex C of the previous edition, EN 13205:2001.
- The scope has been limited to aerosol samplers, and the current version of the standard is not (directly) applicable to other types of aerosol instruments.
- As this is now a standard in its own right, a clause on used symbols has been added. Almost all definitions are now given either in EN 1540, Workplace exposure — Terminology or in Part 1 of this standard.
- The method of calculating the uncertainty of a sampler or a measuring procedure has been revised in order to comply with ENV 13005. The concept of “accuracy” is no longer used, instead the concept of “expanded uncertainty” is used.
- The main part of the standard states how to determine the performance of an aerosol sampler at a specific workplace. This is an adaption of the laboratory method given in Part 2.
- The standard gives a method on how to determine the dependence of the sampling efficiency on the collected mass or internally separated mass.
