Methods of measurement for radio equipment used in the mobile services. Part 5: Receivers employing ...
Deals with the definitions, the conditions and the methods of measurement used to ascertain the performance of receivers having audio-frequency bandwidths generally not exceeding 10 kHz for the reception of voice and other types of signals, using single-sideband amplitude modulation. The standard is intended to be used in conjunction with IEC 60489-1.
Methods of measurement for radio equipment used in the mobile services. Part 6: Selective-calling an...
Refers specially to mobile radio receivers having audio-frequency
band-widths generally not exceeding 10kHz for the reception of
voice and other types of signals, using:
a) angle (Type G or F: phase or frequency) modulation, or
b) double-sideband amplitude (Type A) modulation with full carrier,
c) or single-sideband amplitude (Type H, J or R) modulation with
full, reduced or suppressed carrier.…
Plastics — Friction and wear by sliding — Identification of test parameters
Identifies the parameters associated with the friction and wear of plastics and the conditions that the test methods should address to determine these characteritics. It is intended to provide a basis for further International Standards dealing with friction and wear test methods and specifications of materials.
Building construction — Jointing products — Determination of extrudability of sealants using standar...
Applies to all sealants regardless of the kind of packages in which they are supplied or from which they are applied to the joint in buildings. A defined volume of sealant is extruded from a standardized device under defined conditions by means of compressed air and recorded depending on time.

Photography — Front lens barrels up to 127 mm — Dimensions important to the connection of auxiliarie...
Specifies a standard series of diameter sizes for the front part of a lens barrel and a standard series of thread sizes for the same front barrel. The data are applicable to lenses of cameras, enlargers and similar equipment. They are meant to simplify the production and storage of such auxiliaries as screw-in filters.
Oil of vetiver (Vetiveria zizanioides (Linnaeus) Nash)
