Methods of measurement of the suppression characteristics of passive radio interference filters and ...
Prescribes methods of measurement of insertion loss of passive radio frequency suppression filters, which may consist of single elements, such as capacitors, inductors or resistors, or combinations of inductors, capacitors and resistors of either the lumped or distributed types. The methods include those for use in a laboratory or on a production line, utilizing fixed impedance terminations or…

Laboratory sintered (fritted) filters — Porosity grading, classification and designation
Filters are graded according to their pore size index in one of the eight classes specified. This is applicable to laboratory filters made of glass, vitreous silica, ceramics, metals and plastic materials. Annex A specifies a method for determination of pore size index. Annex B and C concern with a procedure for assessing uniformity of filters and for determination of air permeability.
