Foreword
This Standard is drafted in accordance with the rules given in GB/T 1.1-2009.
This Standard is developed and mainly referenced to GB 9254 “Limits and methods of
measurement of radio interference characteristics of information technology
equipment”, GB/T 17618 “Information technology equipment - Immunity characteristics
- Limits and methods of measurement”, GB 19286 “Electromagnetic compatibility
requirement and measurement methods for telecommunication network equipment”.
This Standard replaces YD/T 983-1998 “Limits and methods of measurement of
electromagnetic compatibility for telecommunication Power supply equipment” from
the date of implementation.
Compare with YD/T 983-1998, the main changes of this Standard are as follows.
- SPECIFY that the telecommunication power supply equipment in this Standard
does not include UPS (see Clause 1);
- ADD the frequency range of 1 GHz ~ 6 GHz for radiation disturbance test (see
8.2).
- MODIFY the classification and limits of harmonic current equipment (see 8.3);
- EXPAND the frequency range of radiated, radio-frequency, electromagnetic field
immunity to 2.7 GHz (see Clause 9);
- SPECIFY the immunity level of telecommunication power supply equipment in
telecommunication centers and other-than-telecommunication centers (see
Clause 9).
Attention is drawn to the possibility that some of the contents of this document may be
the subject of patent rights. The issuing agency of this document shall not be held
responsible for identifying any or all of such patent rights.
This Standard was proposed by and shall be under the jurisdiction of China
Communications Standards Association.
This Standard is drafted by Telecommunication Research Institute of the Ministry of
Industry and Information Technology of the People’s Republic of China.
Main drafters of this Standard. Tang Weisheng, Zhou Yi, Zhang Yunzhuan, Lu
Bingsong.
This Standard was first issued on October 28, 1998. This is the first revision.
Limits and methods of measurement of
electromagnetic compatibility of
telecommunication power supply equipment
1 Scope
