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.

Specification is given for the standardization of test methods and order of tests, selection and modification of test intensities, selection of package attitude, compilation of test schedules and determination of criteria of acceptance. An annex specifies…
Road vehicles — Brake linings — Resistance to water, saline solution, oil and brake fluid — Test pro...
Specifies a laboratory method for exposing samples to detrimental environments, measuring the effect on strength and shape and comparing the results with those from uncontaminated samples. Applies to drum brake linings and disc brake pads being of organic content and intended for service on road vehicles.
Road vehicles — Brake linings — Seizure to ferrous mating surface due to corrosion — Test procedure
Specifies a laboratory method for conditioning brake linings in an environment that will promote corrosion, and a test method to assess the strength of bond formed by corrosion. For comparison of lining behaviours, it is essential that the material and condition of ferrous mating surfaces be constant and repeatable. Applies to drum brake linings and disc brake pads fitted to the brakes of road…
Alpine skis — Determination of the elastic properties
Specifies laboratory measurement methods to determine the elastic properties of alpine skis. Its purpose is to calculate the resistance of defined parts of the ski to bending and torsion.
