Nanotechnologies. Air filter media containing polymeric nanofibres. Specification of characteristics and measurement methods has-tracked-changes — information from contractor to1 Scope This document specifies the characteristics to be measured of air filter media containing polymeric nanofibres on the surfaces of a substrate. It also describes measurement methods for determining the individual characteristics. This document does not cover characteristics specific for health and safety issues. NOTE The properties performances assessment of air filter media related to applications requires the use of relevant published
