How do I collect a dust sample for testing?

Collecting a representative dust sample requires more than sweeping material into a container. Sample location, collection method and handling all affect the accuracy of results. Dust captured at the point of generation behaves differently than dust collected from surface accumulation, and sample size, moisture and contamination can all compromise testing outcomes. For most applications, sampling should be conducted or supervised by a qualified professional using documented protocols — especially when results will be used for a DHA, compliance evaluation or system design
