Standards

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.

This international standards applies to electric iron for household or similar use. The purpose of this standard is to state and define the principal performance characteristics of electric iron for household or similar use which are of interest to the user and to describe the standard methods for measuring these charcteristics.

This standard applies to radio receivers of any excluding television receivers and to the parts of which they are composed or which are used as auxiliaries to such receivers, excluding those dealt with in IEC publication 94, 98, and 268. This standard deals with the determination of performance, the comparison of equipment and the determination of proper practical applications by listing the characteristics which are useful for specifications and down uniform methods of measurement for these characteristics.

This International standard deals with the safety of electrical appliances for household and similar purposes, their rated being not more than 250 V for single - phase appliances and 480 V for other appliances. Appliance not intended for normal household use but which nevertheless may be a source of danger to the public. such as appliances intended to be used by laymen in shop, in light industry and on farms, are within the scope of this standard.

This International standard deals with the safety of electric dry irons and steam irons, including those with a separate water reservoir or boiler having a capacity not exceeding 5.1 . for household and similar purposes, their rated voltage being not more than 250V. Appliances not intended for normal household use, but which nevertheless may be a source of danger to the public, such as appliances intended to be used by laymen in shops, in light industry and on farms, are within the scope of this standard.

This clause of Part 1 is replaced by the following . This International standard deals with the safety of electric portable appliance hold purposes that have a cooking function such as baking , roasting and grilling their rated voltage being not more than 250V.

This clause of Part 1 is replaced by the following : This International standards deals with the safety of electrical motor-operated vacuum cleaners and includes appliances and stationary equipment specifically designed for wet suction, dry suction, or wet and suction for industrial and commercial use with or, without attachments, for example for suction to withdraw dust or the like from work benches and production machines, their rated voltage being not more than 250V for single-phase appliances and 480 V for other appliances.
