Connectors for frequencies below 3 MHz - Part 16: Printed circuit board mounted connectors with two ...
Connectors have 17, 29, 41, 53, 65, 72, 84 or 96 contacts for solder or wrapped connections. Male-female guides ensure polarizing, guiding and coding, with 36 coding possibilities.
Rating 120 V (r.m.s.), 3 A. Climatic category 55/125/56 or 25/085/21.
Basic environmental testing procedures - Part 2: Tests - Test Kc: Sulphur dioxide test for contacts ...
Provides an accelerated means of assessing the corrosive effect of atmospheres polluted with sulphur dioxide on contacts and connections.
Has the status of a basic safety publication in accordance with IEC Guide 104.
Basic environmental testing procedures - Part 2: Tests. Test Kd: Hydrogen sulphide test for contacts...
Provides an accelerated means of assessing the effect of tarnishing on silver and silver alloys used for contacts and connections. Is particularly suitable for comparative information, but not as a general corrosion test, i.e. it may not predict the behaviour of contacts and connections in industrial atmospheres. The objects are: a) to determine the influence of atmospheres containing hydrogen…
Applies to three-phase and single-phase transformers including autotransformers. Defines the rating and connection symbols. Gives certain specifications for transformers having a tapped winding. Defines information which shall be marked on the rating plate and the tests to be conducted. Supersedes IEC 76(1967) and IEC 76-4 (1976).
Classification of electrical and electronic equipment with regard to protection against electric sho...
Defines classes of electrical and electronic equipment regarding protection against electric shock. Applies to equipment intended for connection to an external power supply with voltages up to 440 V r.m.s. between phases and 250 V r.m.s. between phases and earth, for use by the general public in homes, offices, workshops, schools, farms and the like, and for medical and dental purposes. Has the…
Principles of structural fire-engineering design with special regard to the connection between real ...
Describes the basic characteristics of the process of fire development, and gives information based on differentiated temperature-time-curves and on an empirical time of fire duration.
Road vehicles — Injection nozzle holder with body, types 8 and 10, and injection nozzle holder with ...
Specifies the dimensional requirements necessary for mounting and interchangeability of nozzle holders. Some figures illustrate shapes, dimensions and tolerances, and reference quantities of concern. The location of the fuel inlet and leak-off connections are not defined, because they vary according to the particular application.
The requirements deal with the geometric charateristics to ensure interchangeability. The dimensions of the joint-ground zone and the outer diameter of the tube connected to the joint are given in a table and illustrated in a drawing. In addition the surface finish is specified. A system of gauges (stell balls) for testing the ball cup is tabled. In the annex a method of testing the leakage…
