SURVEY ON EMC/EMI
Replies to the Survey
Communication from Hong Kong, China
The following communication, dated 27 May 2002, has been received from the Permanent
Mission of Hong Kong, China.
_______________
1. (a) Does your government have mandatory technical requirements for
electromagnetic interference of Informatio n Technology equipment?  If so, please
identify.
Yes.  Control of interference is regulated under the Subsidiary Regulations of the
Telecommunications Ordinance, Chapter 106B (Control of Interference).  Chapter 106B
specifies the limits of radiated interference from Information Technology equipment.
(b) Are these requirements harmonized with CISPR 22?  If not, please explain the
current requirements.
The limits of radiated emissions of Information Technology equipment in Chapter 106B are
the same as the requirements in CISPR 22.
2. (a) Does your government have mandatory technical requirements for
electromagnetic immunity of Information Technology equipment?  If so, please identify.
No.  We do not specify interference immunity requirement in Chapter 106B as it will depend
on design of the equipment to work in the intended environment.
(b) Are these requirements harmonized with CISPR 24?  If not, please explain the
current requirements.
Not applicable.
3. (a) What conformity assessment procedure for electromagnetic compatibility
(EMC/EMI), which includes both interference and immunity, does your government
require for approval of information technology products?
We do not establish EMC/EMI conformity test procedures.  In addition, neither certification
nor labelling is required for demonstrating the equipment’s compliance with EMCG/IT/SPEC/Q4/9

requirements. However, manufacturers or equipment suppliers should ensure that their
products are in compliance with the EMC requirements, which are based on CISPR 22.
(b) May suppliers perform these procedures (e.g. testing, declaration of conformity),
or must third parties perform these procedures?
Not applicable.
(c) What international guidelines or standards, if any, are those procedures based
on?  If not, what guidelines or standards are they based on ?
Not applicable.
4. Has your regulatory authority received any complaint or had any problems regarding
the EMC/EMI aspects of the approved information technology products?  If yes, how
frequent?  And please identify the nature of the complaint/problem.
No, we have not received any complaints of interference caused by Information Technology
equipment.
