5. Our advice

5.1 Ask questions to accredited organizations

Don't hesitate to ask for several quotes from different accredited organizations, so you can compare the sampling strategies on offer. In addition, make sure that the accredited organization is capable of clearly drafting the report presenting the conclusions of the measurements. In particular, check whether or not sampling will be subcontracted to an accredited laboratory.

The practical execution of sampling is also of prime importance. Flexibility regarding sampling days is essential. In addition, you need to ensure that accredited organizations offer sampling times that are compatible with your organization. The use of standardized sampling methods is also important.
