Quartz crystal units for frequency control and selection. Part 3: Standard outlines and pin connecti...
Loose-leaf booklet containing standard outlines and pin connections. Thirty-four standard sheets are included and supplements will be issued as new outlines are developed.
This standard applies to track systems for ordinary interior use with two or more poles and with provision for earthing (Class 1), with a rated voltage not exceeding 440 V between poles (live conductors), rated frequency not exceeding 60 Hz and a rated current not exceeding 16 A per conductor for the connection of luminaires to the electrical supply.
Audiovisual, video and television equipment and systems. Part 1: General
Gives a complete list of all parts of this standard. Specifies atmospheric conditions for measurements and mechanical checks, frequencies of measurements, scales for graphical presentation of data and requirements for marking.
Electromagnetic compatibility of electrical and electronic installations in ships
Code of practice to be used in order to obtain a certain grade of electromagnetic compatibility over the frequency range 10 kHz and 30 MHz in a ship's electromagnetic environment. Classification of equipment and installations. Standard measuring methods and requirements. Practical rules concerning the choice of cables, screening, earthing and bonding techniques. Requirements for vital…
Supplement E - General principles of nuclear reactor instrumentation - Principles of instrumentation...
Deals more particularly with the measuring equipment for fluence rate of neutrons, fuel temperature, coolant temperature and flow, and with the protection system. The IEC 60231 series of standards is no longer up-to-date and will not be revised by IEC. The standards are maintained for the time being for bibliographical purposes and because they were used in the past for the design of nuclear…
Supplement F - General principles of nuclear reactor instrumentation - Steam generating, direct cycl...
Lays down additional standard requirements concerning neutron flux measurements, temperature measurements, measurements on the coolant, and the protection system. The IEC 60231 series of standards is no longer up-to-date and will not be revised by IEC. The standards are maintained for the time being for bibliographical purposes and because they were used in the past for the design of nuclear…
