Road vehicles — Working voltages for lights fitted to motor vehicles and to their trailers
Specifies a method for measuring the working voltages present at the contacts of the filament lamps in the lighting and light signalling devices, and at the terminals of the trailer connector socket. Applies to vehicles propelled by internal combustion engines and equipped with lead-acid batteries, as defined in ISO 3833 (motorcycles excluded).
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…
Measurement of transformer and reactor sound levels
Defines the methods by which the sound levels of transformers, reactors and their associated cooling equipment shall be determined so that compliance with any specification requirements may be confirmed and the characteristic of noise emitted in service determined.
Methods for measuring the performance of household electric room heaters of the storage type
Applies to electric storage heaters mainly intended to heat the room in which they are located. States and defines the principal performance characteristics and describes methods for measuring these characteristics.
Essential ratings and characteristics of semiconductor devices and general principles of measuring m...
Gives conditions for electrical tests, for different temperature conditions and for different durations, as well as failure-defining characteristics and failure criteria, which are standardized for each device category. This permits a unique and easy comparison of data presented by different manufacturers, relative to acceptance testing as well as to reliability testing.

Road vehicles — Mounting of mechanical coupling devices on rear cross members of trucks
Specifies the dimensional requirements for mounting coupling devices (hooks or forks). Applies to those vehicles that are currently used for international commercial transport, to be coupled to trailers the towed weight of which is greater than 3,5 tonnes. Defines the categories of weights 1, 2, and 3. Two figures illustrate shapes and reference quantities of concern.
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.
Veneer plywood for general use — General requirements
Deals with sheet material as defined in ISO 2074. Applies to plane panels consisting of at least three plies. Does not apply to panels covered with decorative veneers, coated panels or panels for special use. Specifies the structure of panels, humidity, presentation, characteristics of external and internal plies, and glueing.
