Over the years many electromagnetic compatibility measurement and control standards have been developed.
Many of these are of concern to particuclalar sses of devices such as receivers, transmitters, incidental
radiation devices, etcI. n establishing limits,i t is necessary to relate the measurement technique that is used
to determine compliance with a given limit to the field conditions under which the device being controlled
will actually operate. This recommended practice presents a rationale for developing limits' and recommends
sets of limits that are representativeo f current practice. These limits may be adjusted in particular
applications as circumstances dictate.
As part of the developmento f limits, the following parameters shobue lcdo nsidered:
a) The general properties of both man-made and natural environmental electromagnetic noise (disturbances)
2
b) An understanding of the devices commonly used for measurement of such disturbances and their
properties, which will assist the practitioner in selecting such equipments and associated measurement
techniques for the particular application
c) The rationale that can be used in selecting a consistent seot f limits for emission and immunity (susceptibility),
subject to various environmental constraints (good engineering practice)
These practices are intended to be applicable to individual equipments as well as systemosf various sizes
and, if properly applied, will provide guidanfcoer obtaining both intrasystem and intersystem compatibility.
This recommended practice is organized as follows: Clause 2 references instrumentation and measurement
methods; Clause 3 contains a list of definitions; Clause 4 describes environmental radio noise; Clause 5
describes the selectiono f measurement parameters; Claus6e discusses limit setting; and Annexi s A a bibliography.
