Laboratory glassware — Flasks with conical ground joints
An international acceptable series of flasks is specified concluding: round-bottom, flat-bottom and conical flasks. Two series are specified for each type of round-bottom and flat-bottom flasks. The series differ in heigt and in selection of joint sizes. For conical flasks one series of heights is specified each having different joint sizes. The material must be borosilicate glass 3.3. For the…
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.
