13、 INFORMATION TECHNOLOGY GENERIC CABLING INTRODUCTION TO THE MICE ENVIRONMENTAL CLASSIFICATION FOREWORD 1) ISO (International Organization for Standardization) and IEC (International Electrotechnical Commission) form the specialized system for worldwide standardization. National bodies that are membe

14、rs of ISO or IEC participate in the development of International Standards. Their preparation is entrusted to technical committees; any ISO and IEC member body interested in the subject dealt with may participate in this preparatory work. International governmental and non-governmental organizations

15、 liaising with ISO and IEC also participate in this preparation. 2) In the field of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1. Draft International Standards adopted by the joint technical committee are circulated to national bodies for voting. Pu

16、blication as an International Standard requires approval by at least 75 % of the national bodies casting a vote. 3) The formal decisions or agreements of IEC and ISO on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technic

17、al committee has representation from all interested IEC and ISO member bodies. 4) IEC, ISO and ISO/IEC publications have the form of recommendations for international use and are accepted by IEC and ISO member bodies in that sense. While all reasonable efforts are made to ensure that the technical c

18、ontent of IEC, ISO and ISO/IEC publications is accurate, IEC or ISO cannot be held responsible for the way in which they are used or for any misinterpretation by any end user. 5) In order to promote international uniformity, IEC and ISO member bodies undertake to apply IEC, ISO and ISO/IEC publicati

19、ons transparently to the maximum extent possible in their national and regional publications. Any divergence between any ISO/IEC publication and the corresponding national or regional publication should be clearly indicated in the latter. 6) ISO and IEC provide no marking procedure to indicate their

20、 approval and cannot be rendered responsible for any equipment declared to be in conformity with an ISO/IEC publication. 7) All users should ensure that they have the latest edition of this publication. 8) No liability shall attach to IEC or ISO or its directors, employees, servants or agents includ

21、ing individual experts and members of their technical committees and IEC or ISO member bodies for any personal injury, property damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication of, use of, or

22、reliance upon, this ISO/IEC publication or any other IEC, ISO or ISO/IEC publications. 9) Attention is drawn to the reference documents cited in this publication. Use of the referenced publications is indispensable for the correct application of this publication. 10) Attention is drawn to the possib

23、ility that some of the elements of this Technical Report, type 3 may be the subject of patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights. The main task of IEC and ISO technical committees is to prepare International Standards. In exceptional circu

24、mstances, ISO/IEC JTC 1 or a subcommittee may propose the publication of a technical report of one of the following types: type 1, when the required support cannot be obtained for the publication of an International Standard, despite repeated efforts; type 2, when the subject is still under technica

25、l development or where, for any other reason, there is the future but not immediate possibility of an agreement on an International Standard; type 3, when the technical committee has collected data of a different kind from that which is normally published as an International Standard, for example st

26、ate of the art. 4 TR 29106 ISO/IEC:2007(E) ISO/IEC 29106, which is a Technical Report of type 3, has been prepared by subcommittee 25: Interconnection of information technology equipment, of ISO/IEC joint technical committee 1: Information technology. Technical reports of types 1 and 2 are subject t

27、o review within three years of publication to decide whether they can be transformed into International Standards. Technical reports of type 3 do not necessarily have to be reviewed until the data they provide are considered to be no longer valid or useful. This Technical Report of type 3 has been a

28、pproved by vote of the member bodies, and the voting results may be obtained from the address given on the second title page. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. TR 29106 ISO/IEC:2007(E) 5 INFORMATION TECHNOLOGY GENERIC CABLING INTRODUCTION TO THE MIC

There are four primary

38、 environmental criteria used to classify an environment: the M element, defining the mechanical characteristics of the environment; the I element, defining the ingress protection characteristics of the environment; the C element, defining the climatic and chemical characteristics of the environment;

39、 the E element, defining the electromagnetic characteristics of the environment. Each of the four primary environmental criteria are further divided into specific parameters and levels for those parameters. The MICE classification for a given location is therefore defined as M a I b C c E dwhere a,

40、b, c and d are the individual sub-classifications (levels) for the M, I, C and E criteria respectively. The suffixes for the four primary environmental criteria are either 1, 2 or 3. For example, the most benign environment is described as M 1 I 1 C 1 E 1whereas the most harsh environment within the

41、 scope of this standard would be defined as M 3 I 3 C 3 E 3 . 4.2 Channel environment The applicable MICE classification may vary along the length of the cabling channel. As shown in the industrial premises cabling example of Figure 1, the ingress protection characteristics of the environment in the

42、 automation area and at the automation island are different from, and more severe than, those characteristics on the factory floor or in the telecommunications room. 1The documents prepared by subcommittee 25 of ISO/IEC joint technical committee 1: Information technology.

44、 local to the cabling. Where no environmental protection is provided to the cabling, the classification of the local environment is also that of the overall environment at that location. However, where technical or economic restrictions preclude the use of components compatible with the overall envi

45、ronment, mitigation or isolation techniques may be applied to modify one or more of the M, I, C or E environments local to the cabling in order to allow appropriate components to be installed. The mitigation or isolation techniques typically involve the use of alternative pathways and/or pathway sys

46、tems as shown in Figure 2. Overall environment Local environment Pathway system providing environmental protection CableFigure 2 The local environment 4.3 Component selection The components used within a channel should be selected to be compatible with the MICE classification of the channel at the p

47、oint where the components are to be installed. Table 1, taken from ISO/IEC 24702:2006, shows the parameters used to classify the local environment under the M, I, C and E criteria. While the classification of an environment is determined by the most demanding parameter within each criteria group, th

48、e selection of components may reflect the specific demands of all the parameters within the group, including those that may be less demanding than the overall classification of the environment. The MICE classification system is intended to address approximately 80 % of the environments to which cabl

49、ing may be subjected. There are some environments beyond the boundaries of M 3 I 3 C 3 E 3 . Such environments are beyond the scope of this Technical Report and require special handling. 8 TR 29106 ISO/IEC:2007(E) Table 1 Details of environmental classification Mechanical M 1M 2M 3Shock/bump (see a) Peak acceleration 40 ms -2100 ms -2250 ms -2Vibration Displacement amplitude (2 Hz to 9 Hz) 1,5 mm 7,0 mm 15,0 mm Acceleration amplitude (9
