适用范围: This Standard applies to continuous methods for monitoring particulate matter size fractions in ambient air, specifying a procedure for determining whether a candidate method is equivalent to the reference method under the ambient conditions experienced at its intended sampling locations. Only instruments that conform with the requirements of EN 15267, or have obtained US EPA equivalent method status, are acceptable as candidate method nstruments for the particulate matter size fraction under consideration.
