Anthropometric Fit Test Methods: Three Case Studies

Abstract

There is not a universally accepted fit test procedure because test protocols need to be customized for specific products or research questions. A fit test protocol can vary significantly based on the product tested, but often includes these steps: define fit criteria, select anthropometric dimensions of interest, perform testing, collect quantitative and qualitative feedback, identify design recommendations, and develop or refine a sizing chart. To illustrate general approaches to human fit testing, case studies of fit tests are described for three different product types: a multi-layered protective clothing ensemble, a therapeutic airway clearance vest, and a patient transfer sling.
