This second edition cancels and replaces the first edition (i.e. ISO 3908:1976). The method is applicable to some carbides, mixtures of these carbides and binder, all grades of presintered or sintered hardmetals, produced from these carbides, having an insoluble carbon content between 0,02 and 0,5 % (m/m). Specifies principle, reagents, apparatus, sampling, procedure, expression of results and…

Specifies the test methods to be used for testing polymeric insulating and sheathing materials of electric cables for power distribution and telecommunications including cables used on ships. Gives the methods for pressure test at high temperature and for tests for resistance to cracking, which apply to PVC compounds. The contents of the corrigendum of May 1986 have been included in this copy.

Applies to insulating foam-filled tubes and solid rods made of synthetic materials and intended for tools and equipment for live work on systems operating at voltages above 1 kV. The contents of the corrigendum of July 1999 have been included in this copy.

Describes two procedures each using different apparatus to measure the tendency of insulating liquids to evolve or absorb gas when subjected to electrical stress. The contents of the corrigendum of October 1986 have been included in this copy.

Specifies the test methods to be used for testing polymeric insulating and sheathing materials of electric cables for power distribution and telecommunications including cables used on ships. Gives the methods for loss of mass test and thermal stability test, which apply to PVC compounds. The contents of the corrigendum of May 1986 have been included in this copy.

Provides basic mating and performance information for subminiature coaxial connectors with overlapping polytetrafluoroethylene (PTFE) dielectric interface for use with flexible and semi-rigid r.f. cables. The connectors are usable up to a frequency of 3 GHz. Only the interface dimensions are standardized. Other technical data are supplied for guidance only. The contents of the corrigendum of…
