Applies to transverse track recorders, i.e. recorders making use of four video heads rotating in a plane perpendicular to the direction of tape motion. Defines the electrical and mechanical characteristics of equipment which will provide for interchangeability of recordings. The clauses of this standard are in
accordance with CCIR specifications, unless otherwise specified.
See IEC 752.
Methods for measuring the performance of water-heaters for household purposes
States and defines the principal performance characteristics of electric storage water-heaters which are of interest to the user and to describe the standard methods for measuring these characteristics.
This standard is concerned neither with safety nor with performance requirements.
Test methods for batch furnaces with metallic heating resistors
Applies to industrial furnaces heated indirectly with metallic heating elements in which the internal atmosphere is composed of air not intentionally modified. Standardizes testing conditions and methods in order to determine the essential parameters and technical data of batch chamber, bell, elevator, shaft and carriage furnaces, either with or without forced air circulation, as well as of…
Standard sheets for barrel thread for E14 and E27 lampholders with shade holder ring
Gives limit dimensions of thread for metal or plastic and ceramic lampholders with shade holder rings made of metal or plastic. Dimensions for 'Go' and 'Not go' gauges for shade holder rings and for lampholders are also included.
Test methods for induction furnaces with submerged channels
Standardizes test methods to determine the essential parameters and technical characteristics of electro-heat installations comprising industrial induction channel furnaces for melting, holding and super-heating.
Symbols for alternating-current electricity meters
Applies to letter and graphical symbols for a.c. electricity meters and their auxiliary devices, independent of induction or static measurement elements. All the symbols included in this standard may be marked on the name-plate, dial plate, external labels or accessories of the meter.
Supplement B - General principles of nuclear reactor instrumentation - Principles of instrumentation...
Applicable more particularly to instrumentation for direct cycle boiling water power reactors and includes a new clause concerning reactor control. 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 power plants which…
Measurement of the electrical properties of microwave tubes. Part 1: Terminology
This new edition contains many new terms associated with pulse operation of microwave tubes as well as new terminology relating specifically to amplifier tubes and oscillator tubes. Four new sections covering terminology applicable to disk seal tubes, magnetrons, high-power klystrons and gas-filled microwave switching tubes have been added. This recommendation provides users and manufacturers of…
