5、e IEEE Societies and the Standards Coordinating Committees of the IEEE Standards Board. Members of the committees serve voluntarily and without compensation. They are not necessarily members of the Institute. The standards developed within IEEE represent a consensus of the broad expertise on the sub
6、ject within the Institute as well as those activities outside of IEEE which have expressed an interest in participating in the development of the standard. Use of an IEEE Standard is wholly voluntary. The existence of an IEEE Standard does not imply that there are no other ways to produce, test, mea
7、sure, purchase, market, or provide other goods and services related to the scope of the IEEE Standard.Further more, the view point expressed at the time a standard is approved and issued is subject to change brought about through developments in the state of the art and comments received from users
8、of the standard. Every IEEE Standard is subjected to review at least every fi ve years for revision or reaffi rmation. When a document is more than fi ve years old, and has not been re affi rmed, it is reasonable to conclude that its contents, although still of some value, do not wholly refl ect the
9、 present state of the art.Users are cautioned to check to determine that they have the latest edition of any IEEE Standard. Comments for revision of IEEE Standards are welcome from any interested party, regardless of membership affi liation with IEEE. Suggestions for changes in documents should be i
10、n the form of a proposed change of text, together with appropriate supporting comments. Interpretations: Occasionally questions may arise regarding the meaning of portions of standards as they relate to specifi c applications. When the need for interpretations is brought to the attention of IEEE, th
11、e Institute will initiate action to prepare appropriate responses. Since IEEE Standards represent a consensus of all concerned interests, it is important to ensure that any interpretation has also received the concurrence of a balance of interests. For this reason IEEE and the members of its technic
12、al committees are not able to provide an instant response to interpretation requests except in those cases where the matter has previously received formal consideration. Comments on standards and requests for interpretationsshould be addressed to: Secretary, IEEE Standards Board 345 East 47th Street

This is a major revision
16、 of IEEE Std 139-1952 . It recommends procedures for measuring the radio frequency (rf) energy emitted by industrial, scientifi c, and medical (ISM) equipment installed, ready for use, in the users plant or laboratory. The reader is assumed to be skilled in measuring radio frequency electromagnetic
17、fi elds and familiar with the measurement equipment used. This standard recommends techniques for measuring emissions from ISM equipment installed, ready for use, or actually being used, on users premises; it is not intended for testing equipment on a test site, or as it comes off a production line.
18、 While there may be similarities in the measurement of emissions under these two conditions, there are major differences also. Some differences are: 1) The ISM equipment measured on users premises may have been modifi ed. These modifi cations may not always have the careful quality control that it i
19、s reasonable to expect from new equipment manufactured on a production line. Therefore, this standard provides more testing for prototype verifi cation of compliance than might be considered necessary in a production environment. Hence the recommendation that all equipment be inspected, and its emis
20、sion spectrum checked, with the “prototype” machines being subjected to more thorough emission tests. 2)The emission from installed ISM equipment may interact with emissions from other rf equipment installed nearby, generating spurious emissions at heterodyne, harmonically related, and other frequen
21、cies. The emission at these frequencies must also be checked. At the time this standard was approved, the Working Group on ISM Equipment Emission Measurements had the following membership: Daniel I. Weinberg , Chair Edwin L. Bronaugh Myron L. Crawford Glen Dash George E. Lee Leanard W. Thomas, Sr Ar
