Standards

This standard applies to the dimensional, mechanical and electrical requirements for non perforated blank and pre-recorded magnetic tape and for the associated recording and reproducing systems such as reel-to-reel, cassette and cart . The methods of measurements and the necessary tolerance to secure interchangeability of recordings are included.

This part of IEC 107 deals with the general methods of measurement of the audio channels of receivers for monophonic systems and multichannel sound systems. General considerations for the measurement are specified in IEC 107-1 and the measurement specific to multichannel sound systems are dealt with by IEC 107-3, IEC 107-4 and IEC 107-5 measurements for non-broadcast signals are dealt with by IEC 107-6.

The methods of measuring the electrical characteristics described in this standard apply particularly to broadcast television receivers designed for the reception of multichannel sound systems using subcarriers.

This part of IEC 107 deals with the standard conditions and methods of measurement on high definition television (HDTV) displays . Such may be used as an integral part of an HDTV receiver for direct off-air reception reception via cabled networks , or as a monitor for pre- recorded video home movies and games, other applications.

This standard deals only with the methods of measurement for colour - television picture tubes with there electron beams and shadow mask.

This recommendation applies to single high-voltage connecting wires insulated with thermoplastic material with a rated voltage up to and including 20 kV d.c. and a maximum working temperature of 85C. This wire was originally developed for use in television receivers, but may be suitable for similar applications.

This international standard describes the methods of measurement for assessing the performance characteristics of television transmitters. To assess all other characteristics, this standard needs to be used in conjunction with the publication quoted in clause2.

This part of IEC 244 is intended to be used for tape tests and acceptance or factory tests and may be used to checks the characteristics of a demodulator used for measurement television transmitters and transposes. It is mandatory to measure all the described characteristics.

This standard applies to television transmitters and transpose operation in accordance with television systems for monochrome and color transmission employing 625 or 525 limes as described in CCIR publications. For details of the characteristics of the various systems, see the CCIR Report (1) mentioned in Appendix C.

This recommendation applies to single high tension connection wires with thermoplastic insulation and having a rated working voltage of 20 kV and 25 kV d.c. and a working temperature of 105 C . This type of wire was originally developed for use in television receivers, but may be suitable for similar applications.
