Title of document

Nanotechnologies- ~~Nano-enhanced air~~ filter media ~~using~~ nanofibres; ~~Characteristics,~~ ~~Performances~~ and ~~Measurement Methods~~

Nanotechnologies — Air filter media containing polymeric nanofibres — Specification of characteristics and measurement methods

196

Scope/description

-	This ~~standard~~ specifies ~~various physical, structural, chemical~~ characteristics of ~~the nanofibers( NFs) utilized in nano-enhanced~~ air ~~filter (NEAF)~~ media ~~and their relevant characterization methods~~. ~~Further, it~~ also ~~addresses~~ the ~~relevant~~ characteristics~~/properties and performances of the media. This technical specification does not cover characteristics specific for health and safety issues~~.	+	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.
-	~~Note1.~~ This document does not ~~deal with the required standard specifications~~ of the ~~substrate~~. The ~~user or buyer needs to refer to~~ the ~~related standard documents~~.	+	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 standards. The physical properties and performances of filtration media, such as pressure drop, and the particle removal efficiency of air filter media are measured with test methods suitable for specific applications.
