CEN/TC 137/WG 5 - Measurement of biological agents

This document specifies general requirements for the evaluation of volumetric bioaerosol samplers in order to assess workplace exposure and their physical and biological performance.
This document describes the procedures for the development of volumetric bioaerosol samplers as well as their properties and validation.
This document provides a description of a test facility and selection criteria for microbial strains that can be used to assess their biological performance.
This document addresses requirements to manufacturers and developers of volumetric bioaerosol samplers as well as to test facilities with the equipment and skills to carry out the performance measurements of these samplers (see Annex D for application guidance).
This document is not intended for operators who use volumetric bioaerosol samplers to carry out exposure measurements for workers at occupational settings.
This document is not applicable for clean room measurements other than for occupational safety.

This document specifies methods for the quantitative measurement of airborne endotoxins and gives general requirements for sampling on filters, transportation, storage as well as the analysis of samples.
This document provides also guidelines for the assessment of workplace exposure to airborne endotoxins.

This document specifies requirements and test methods to determine the performance of volumetric sampling devices used to assess bioaerosols in the workplace.
For clean room measurements EN ISO 14698-1 is applicable.

Measurement of endotoxin from workplace atmospheres. The standard provides methods for measurement, transportation and determination of endotoxin in the sample.

The European Standard provides guidelines for the assessment of workplace exposure to airborne micro-organisms including the determination of total number and culturable number of micro-organisms in the workplace atmosphere. The Standard also provides methods for measurement of airborne endotoxin in the work environment. The European Standard does not apply to viruses, specific pathogenic micro-organisms and toxins other than endotoxin, although some of themeasurement principles may be the same.
