ISO TS 21237 is a standard that discusses the specification and measurement methods for nanotechnologies. ISO TS 21237 describes the measurement methods for determining the individual characteristics. ISO TS 21237 specifies the characteristics to be measured of air filter media containing polymeric nanofibres on the surface of a substrate. Note: ISO TS 21237 does not cover the characteristics specific to health and safety
