Gives general requirements for the measurement of radio-frequency emissions emanating from measuring relays and protection equipment for power system protection. Includes control, monitoring and proc process interface equipment used with such systems. Based on CISPR 22. Defines the limits of acceptable conducted and radiated emissions and specifies test procedures. The object of the tests is to confirm that the equipment being tested will not cause conducted or radiated emissions above defined levels which might affect the satisfactory operation of other equipment. Any equipment or part of equipment which has the primary function of radio transmission and/or reception is excluded from this standard. Requirement defined are applicable to measuring relays and protection equipment in a new condition, all are type test onl

IEC 60332-1-3:2004 Specifies a test procedure for assessment of falling flaming droplets/ particles when a single vertical electrical insulated conductor or cable, or optical fibre cable, is subjected to defined fire conditions. NOTE - Testing to IEC 60332-1-3 may be performed simultaneously with that to IEC 60332-1-2, if required. Recommended requirements for performance are given in Annex A. IEC 60332-1-3 specifies the use of a 1 kW pre-mixed flame and is for general use, except that the procedure specified may not be suitable for the testing of small single insulated conductors or cables of less than 0,5 mm2 total cross-section because the conductor melts before the test is completed, or for the testing of small optical fibre cables because the cable is broken before the test is completed. It has the status of a horizontal standard in accordance with IEC Guide 104.
