This standard has been prepared as a guide for the application of
the International System of Units (SI). Information is included
on SI units, recommended application of multiples and
sub-multiples of the units, up-to-date terminology concerning the
names of quantities, conversion factors that relate the SI and
the yard/pound system, conversion and rounding of data, and dual
dimensioning.
Covers the writing, typing, and printing of dates and times when
all-numeric forms are used, and is applicable for general use. It
is more restrictive than, but is not in conflict with, the
relevant ISO standards. It departs from International Standard
ISO 3307, Information interchange Representations of time of

Method for the determination of the proof and the comparative tracking indices of solid insulating m...
Specifies the method of test for the determination of the proof and comparative tracking indices of solid insulating materials on pieces taken from parts of equipment and on plaques of material using alternating voltages. The standard provides for the determination of erosion when required. Test results cannot be used directly for the evaluation of safe creepage distances when designing…
FORMERLY NUMBERED IEC 651
This standard describes instruments (sound level meters) for the measurement of certain frequency and time weighted sound pressure levels.
Piezoelectric ceramic resonators and resonator units for frequency control and selection - Chapter I...
Establishes uniform conditions for assessing the mechanical and climatic properties of ceramic resonators, describes test methods, gives recommendations for standard values and gives guidance for the use of such resonators.
Specification for high-voltage fuse-links for motor circuit applications
Applies primarily to fuse-links used with motors started direct-on-line on alternating current systems of 50 Hz and 60 Hz. Standardizes time-current characteristics to formulate additional pulse withstand requirements regarding testing and to give guidance for the selection of fuse-links to be used with motors.
Note: -Fuse-links according to this specification should comply with the requirements…
Standard interface between a number of 'CAMAC' measuring instruments, display units, control units, actuators, data processing equipment (computers) and communication equipment.
Methods of measurement for radio transmitters. Part 7: Cabinet radiation at frequencies above 1 GHz
Specifies the method which is essentially the same as that described in CISPR publication 11, sub-clause 5.2.2. With this method, emphasis has been laid on simplicity and reproducibility, rather than on rigorous scientific method. lt has been purposely developed for use in an ordinary laboratory room to avoid the use of an expensive anechoic room. The method is intended for type tests but it may…
