Industrial and Production Automation Systems Sectional Committee, BP 18 NATIONAL FOREWORD This Indian Standard which is identical with lso/tr 10450:1991 Industrial automation systems and integration Operating conditions for discrete part manufacturing Equipment in industrial environments issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on the recommendation of the Industrial and Production Automation Systems and approval of the Basic and Production Engineering Division Council. The text of the International Standard has been approved as suitable for publication as Indian Standard without deviations. Certain conventions are however not identical to those used in Indian Standards. Attention is particularly drawn to the following: a) Wherever the words International Standard appear referring to this standard, they should be read as Indian Standard. b) Comma (,) has been used as a decimal marker in the International Standard while in Indian Standards, the current practice is to use a point (.) as the decimal marker. Where there is no corresponding Indian Standard for the International Standard referred in this Indian Standard, reference to the relevant International Standard maybe made. For the purpose of deciding whether a particular requirement of this standard is complied with, the final value, observed or calculated, expressing the result of a test or analysis, shall be rounded off in accordance with IS 2:1960 Rules for rounding off numerical values (revised). The number of significant places retained in the rounded off value should be the same as that of the specified value in this standard.

IS 15294:2003 lso/tr 10450:1991 Section 2: Climatic conditions 2.1 Scope This section lists the temperature, temperature gradient, humidity, and the barometric pressure conditions in specified locations to which industrial automation equipment may be exposed during operation or during periods when they are installed but inactive. 2.2 Classiflcatlonof locationsfor discrete pari manufacturing 2.2.1 Class A Air-conditioned locations For this class, both air temperature controlled within specified limits. and humidity are These locations are provided for data processing equipment and other electronic equipment requiring a controlled air environment. 2.2.2 Ciass B Heated and/or cooied enciosed iocations For this class, only air temperature is controlled within specified limits. Temperature control in accordance with location class BI (see table 1) and associated humidity are recommended for work space with normal comfort for operating personnel. Considerable operation discomfort can exist under continued exposure to the extremes of temperatures of classes B2 and B3. Class B locations concern the bulk of equipment in manufacturing where operator surveillance exists on a continuous basis or for several hours each day. It is recommended that storage df the types of equipment covered in this class @ provided in the same class of locations. The enclosed means of transportation are normally considered sheltered locations. 2.2.3 Ciass C Sheltered locations For this class, neither air temperature nor humidity are controlled; the equipment is protected against direct exposure to such climatic elements as direct sunlight, rainfall and other precipitation, and wind pressure. Unheated warehouses and shelters for communication devices (as repeaters) are typical for sheltered locations. 2.2.4 Ciass D Outdoor locations See table 1 and IEC 654-1, Class D. NOTES 1 Temperatures are for air temperatures for location classes A, B, and C; for class D, temperatures are surface temperatures of the equipment or devices. 2 For discrete part manufacturing applications the avoidance of installing and utilizing equipment in such iocations is recommended. 3 The values given in tablet are in accordance with the draft revision of IEC 654-1. The 1979 edition of IEC 654-1 should be used only for the comments given for all the c1asses and locations and for special applications. 2.3 Recommended values of Iocatlonsfor discretepart manufacturingapplications Recommended values (for temperate climate geographical zone) are For Class A (reference IEC 721, 3KI): location class Al. For Class B (reference IEC 721, 3K2): location class B1. For Class C (reference IEC 721, 3K6): location class C2. 3

IS 15294:2003 lso/tr 10450: 1991 Section 6: Electromagnetic compatibility for industrial automation equipment 6.1 SCOPC4 This section is applicable to the electromagnetic compatibility of equipment, It deals with general considerations in the context of the complexity of electromagnetic compatibility and the problems with which manufacturers and users of equipment may be confronted. All equipment, more or less according to its location, is exposed to electromagnetic disturbance generated by various types of industrial equipment To ensure that sensitive electronic circuits perform satisfactorily in service, it is necessary to subject them to disturbance tests which represent and simulate the conditions of disturbance which may occur in their service locations. Interferences may be introduced through several situations; all of them shall be considered and, therefore, all parts of IEC 801 shall be taken into consideration. IEC 801 gives clear indications of the test values to be selected. NOTE 6 IEC 801 is recognized by several professional organizations as a basic document which is valid for a wide spectrum of applications. It deals especially with test procedures and preferred test severity levels. 8
