7 IEC: INTERNATIONAL ELECTROTECHNICAL COMMISSION ALARM SYSTEMS Part 2: Electromagnetic compatibility Immunity requirements for components of fire and security alarm systems FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as IEC Publication(s) ). Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and nongovernmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC National Committees. 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any misinterpretation by any end user. 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carried out by independent certification bodies. 6) All users should ensure that they have the latest edition of this publication. 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of its technical committees and IEC National Committees 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, use of, or reliance upon, this IEC Publication or any other IEC Publications. 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is indispensable for the correct application of this publication. 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC has been prepared by IEC technical committee 79: Alarm and electronic security systems. This standard is based on EN (1995) and its amendments 1 (1998) and 2 (2003), and integrates the most recent ACEC recommendations 1. 1 ACEC: Advisory Committee on Electromagnetic Compatibility is an IEC committee.
8 IEC:2010 The text of this standard is based on the following documents: FDIS 79/277/FDIS Report on voting 79/293/RVD Full information on the voting for the approval of this standard can be found in the report on voting indicated in the above table. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. A list of all parts in the IEC series, under the general title Alarm systems, can be found on the IEC website. The committee has decided that the contents of this publication will remain unchanged until the stability date indicated on the IEC web site under "http://webstore.iec.ch" in the data related to the specific publication. At this date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended.
9 IEC: ALARM SYSTEMS Part 2: Electromagnetic compatibility Immunity requirements for components of fire and security alarm systems 1 Scope This part of IEC for immunity requirements applies to the components of the following alarm systems, intended for use in and around buildings in residential, commercial, light industrial and industrial environments: access control systems, for security applications; alarm transmission systems 2 ; CCTV systems, for security applications; fire detection and fire alarm systems; intruder and hold-up alarm systems; social alarm systems. The tests and severities that should be used are the same for indoor and outdoor applications of fixed, movable and portable equipment. The levels do not cover extreme cases, which may occur in any location, but with an extremely low probability of occurrence, or in special locations close to powerful emitters (e.g. radar transmitters). Equipment within the scope of this standard should be designed in order to operate satisfactorily in the environmental electromagnetic conditions of residential, commercial, light industrial and industrial environments. This implies particularly that it should be able to operate correctly within the conditions fixed by the electromagnetic compatibility levels for the various disturbances on the low voltage public supply system as defined by IEC The immunity tests in this standard only concern the most critical disturbance phenomena. For equipment using radio signalling, mains signalling or with connections to the public telephone system, additional requirements, from other standards specific to these signalling media, may apply. This standard does not specify basic safety requirements, such as protection against electrical shocks, unsafe operation, insulation coordination and related dielectric tests. This standard does not cover EMC emission requirements. These are covered by other appropriate standards. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. 2 Apart from equipment which is part of a public telecommunication network.

(e.g. series for fire alarm systems, series for intruder alarm systems) basic EMC standard standards giving the description of, and test and measurement methods for an EMC phenomenon, along with details of the test apparatus and test set-up NOTE Although a basic EMC standard may give guidance on the choice of severity, it does not give the prescribed limits or criteria for compliance intruder alarm system alarm system to detect and indicate the presence, entry or attempted entry of an intruder into supervised premises
11 IEC: fire detection and fire alarm system alarm system to detect the presence of fire in supervised premises and to raise the appropriate alarm hold-up alarm system alarm system designed to permit the deliberate creation of an alarm condition in the case of a hold-up social alarm system alarm system, providing facilities to summon assistance, for use by persons, who can be considered to be living at risk. 3.2 Abbreviations EUT : equipment under test EMC : electromagnetic compatibility CDN : coupling and decoupling network CW : continuous wave (carrier wave) 4 Application of tests The tests shall be carried out as single tests, as described in the following clauses of this standard, and the equipment shall meet the criteria for compliance for each test. If a number of tests are made on a single specimen of the equipment, the sequence of testing is optional and it is permissible to substitute the intermediate functional tests with a reduced version of the functional test and to conduct a full functional test at the end of the sequence. However, it should be noted that, in this case, in the event of a failure, it may not be possible to identify which test exposure caused the failure. Where appropriate basic EMC standards exist, these are referred to in the relevant clauses. The content of these basic EMC standards (i.e. the description of the test procedure, test apparatus and test set-up) are not repeated here in full. However, modifications or additional information needed for the particular application of the tests are given in this standard. It may be determined, from consideration of the electrical characteristics and usage of particular equipment, that some of the tests are inappropriate and therefore unnecessary. In such a case, it is required that the decision not to conduct the test be recorded in the report, along with the justification for this decision. 5 Conditions during testing 5.1 Configuration If the EUT is part of a system, or can be connected to other equipment, then it shall be tested while connected in at least the minimum configuration necessary for verifying its performance. If the EUT has a large number of inputs/outputs, then a sufficient number shall be selected to simulate actual operating conditions and to ensure that all the different types of inputs/outputs are covered. The connections to inputs and outputs, which may be separated into different cables in a real installation, shall be separated into different cables for the tests (e.g. detector loops).
12 IEC:2010 During conditioning, the EUT shall be monitored to detect any change in its status, including any change in outputs, which could be interpreted by associated equipment as a change in status. 5.2 Environmental conditions Unless otherwise indicated in the basic standard or test procedure, the tests shall be carried out within the rated supply voltage for the EUT and the following standard atmospheric conditions for measurements and tests, as specified in of IEC :1988. temperature: 15 C to 35 C; relative humidity: 25 % to 75 %; air pressure: 86 kpa to 106 kpa. 5.3 Operating condition Where a relevant regional product performance standard exists which defines suitable operating condition(s) during environmental or EMC tests (e.g. series for fire alarm systems, series for intruder alarm systems), the operating condition(s) of the EUT during the test conditions shall be as defined in that standard. Where no relevant regional product performance standard exists, the operating condition(s) of the EUT during the test conditioning shall include at least that corresponding to the main functional mode (appropriate to the test being undertaken) of the system of which it forms part (e.g. corresponding to the "set" mode, for an intruder alarm system during a radiated immunity test). NOTE The configuration and mode(s) of operation during the tests should be precisely noted in the test report. 6 Functional test The variety and diversity of the equipment within the scope of this standard makes it difficult to define a precise functional test for evaluation of the EUT performance: where a relevant regional product performance standard exists which defines a suitable functional test for assessing the performance of the EUT before and after environmental or EMC tests (e.g. series for fire alarm systems, series for intruder alarm systems), the functional test to be applied and its acceptance criteria shall be as defined in that standard; where a relevant regional product performance standard does not exist, the functional test shall be at least a test or measurement of the main function(s) of the equipment. The acceptance criteria for this functional test shall be that there is no change in the functioning of the equipment and no significant change in any measurement (e.g. sensitivity of a detector), which shall also remain within specification. 7 Mains supply voltage variations 7.1 Object of the test To demonstrate the ability of the equipment to function correctly over the anticipated range of mains supply voltage conditions. 7.2 Principle The test consists of exposing the specimen to each of the maximum and minimum power supply conditions for a sufficient time to obtain temperature stability and to perform the functional test.
13 IEC: Test procedure General No reference can be made to an internationally accepted standard at present Initial examination Before conditioning, subject the specimen to the functional test (see Clause 6) State of specimen during conditioning Connect the specimen to suitable power supply, monitoring and loading equipment (see 5.1). The specimen shall be in its operating condition (see 5.3) Conditioning Subject the specimen to each of the power supply conditions, indicated in Table 1, until temperature stability is reached. Table 1 Supply voltage max (U max ) U nom a + 10 % Supply voltage min (U min ) U nom a 15 % a U nom = Nominal mains voltage. Where provision is made to adapt the equipment to suit a number of nominal supply voltages (e.g. by transformer tap changing), the above conditioning severity shall be applied for each nominal voltage, with the equipment suitably adapted. For equipment which is claimed to be suitable for a range of nominal mains voltages (e.g. 220/240 V) without adaptation, U max = (maximum U nom ) + 10 %, and U min = (minimum U nom ) 15 %. In any case the range of U nom shall include the regional nominal mains voltage, e.g. 230 V for Europe Measurements during conditioning Monitor the specimen during conditioning to detect any change in status. When temperature stability has been obtained, at each of the supply conditions, subject the specimen to the functional test (see Clause 6) Final measurements After conditioning, for both of the specified power supply conditions inspect the specimen visually for mechanical damage. 7.4 Criteria for compliance There shall be no damage, malfunction or change of status due to the different supply voltage conditions. During conditioning, the EUT shall meet the acceptance criteria for the functional test (see Clause 6). 8 Mains supply voltage dips and short interruptions 8.1 Object of the test To demonstrate the immunity of the equipment to short duration dips (reductions) and interruptions in the a.c. mains voltage, such as those caused by load switching and operation of protection devices on the mains distribution network.
14 IEC: Principle The test consists of applying short duration dips and interruptions to the a.c. mains supply to the equipment. 8.3 Test procedure General The test apparatus and procedure shall be as described in IEC Initial examination Before conditioning, subject the specimen to the functional test (see Clause 6) State of specimen during conditioning Connect the specimen to a suitable power supply, monitoring and loading equipment (see 5.1). The specimen shall be in its operating condition (see 5.3) Conditioning Reduce the a.c. mains supply voltage from the nominal value by the following reductions for the specified periods in accordance with Table 2. The voltage changes shall occur at the zero crossings of the voltage wave. Table 2 Voltage reduction % Duration of reduction (no. of periods) (i.e. cycles of the voltage wave) 250/300 a 25/30 a 10/12 a 0,5; 1; 250/300 a Number of reductions at each duration Interval between reductions s a The lower number is for 50 Hz testing and the higher number for 60 Hz testing Measurements during conditioning Monitor the specimen during the conditioning period to detect any change in status Final measurements After conditioning, subject the specimen to the functional test (see Clause 6), and inspect it visually for mechanical damage. 8.4 Criteria for compliance There shall be no damage, malfunction or change of status due to the conditioning. Flickering of an indicator during conditioning is permissible, providing that there is no residual change in the EUT or any change in outputs, which could be interpreted by associated equipment as a change. After conditioning, the EUT shall meet the acceptance criteria for the functional test (see Clause 6).
15 IEC: Electrostatic discharge 9.1 Object of the test To demonstrate the immunity of equipment to electrostatic discharges caused by personnel, who may have become electrostatically charged, touching the equipment or other equipment nearby. 9.2 Principle The test consists of the application of electrostatic discharges onto parts of the equipment accessible to the operator and onto coupling planes 0,1 m from the equipment. The discharges are generated by apparatus intended to simulate the capacity and discharge resistance of a human body. 9.3 Test procedure General The test apparatus and procedure shall be as described in IEC The test procedure for type tests performed in laboratories shall be used. For wall and ceiling mounted equipment, follow the procedure for floor standing equipment, but with the equipment arranged with its normal mounting surface 0,1 m from the earth reference plane. Contact discharges shall be applied to conductive surfaces and the coupling plane(s) and air discharges shall be applied to insulating surfaces. Ten direct discharges shall be applied, at each test voltage to each preselected point, on any part of the specimen, which is normally accessible when in the installed condition or is accessible to the normal operator. Ten indirect discharges shall be applied via the appropriate coupling plane(s). Unless stated otherwise in a product related standard, surfaces only accessible during infrequent service by the end user or a service engineer (e.g. battery terminals) may be excluded, providing there is an appropriate ESD hazard symbol or warning associated with these surfaces and appropriate ESD mitigation procedures are given in the operating instructions Initial examination Before conditioning, subject the specimen to the functional test (see Clause 6) State of specimen during conditioning Connect the specimen to suitable power supply, monitoring and loading equipment (see 5.1). The specimen shall be in its operating condition (see 5.3) Conditioning Apply the severity of conditioning indicated in Table 3: Table 3 Test voltages a : Air discharges (kv) 2, 4 and 8 Contact discharges (kv) 6 Polarity + and Number of discharges per point for each voltage and polarity 10 Interval between discharges (s) 1 a The test voltages specified are the open-circuit voltages. Where the test voltages for the lower severity levels are included, they shall also be satisfied.
16 IEC: Measurements during conditioning Monitor the specimen during the conditioning period to detect any change in status Final measurements After conditioning, subject the specimen to the functional test (see Clause 6), and inspect it visually for mechanical damage. 9.4 Criteria for compliance There shall be no damage, malfunction or change of status due to the conditioning. Flickering of an indicator during the application of the discharges is permissible, providing that there is no residual change in the EUT or any change in outputs, which could be interpreted by associated equipment as a change. After conditioning, the EUT shall meet the acceptance criteria for the functional test (see Clause 6). 10 Radiated electromagnetic fields 10.1 Object of the test To demonstrate the immunity of equipment to electromagnetic fields (e.g. such as produced by portable radio transceivers, radio telephones etc.) Principle The test consists of exposing the equipment to electromagnetic radiation swept between 80 MHz and 2,7 GHz. The equipment is exposed to both sinusoidal amplitude modulated and pulse modulated (switched CW) signals. The pulse modulated exposure has been added as it has been found by experience that some components of alarm systems are particularly susceptible to pulsed or switched signals Test procedure General The test apparatus and procedure shall be as described in IEC , with the following modifications and clarifications taken into account. The electromagnetic fields can be generated by the use of antennas in anechoic or semianechoic chambers or by other means (e.g. TEM or GTEM cells), providing fields with the required uniformity and repeatability can be generated in a large enough test area for the EUT. The conditions (e.g. power levels) required to generate the required CW field strength, in the position to be occupied by the EUT (test area), shall be established, throughout the frequency range (80 MHz to 2,7 GHz), before the test. The EUT shall then be installed in the test area and the frequency range shall be swept using these conditions, with the required modulation applied, to subject the EUT to the severity of conditioning specified in Where the frequency range is swept incrementally, the step size shall not exceed 1 % of the fundamental frequency (i.e. the frequency of the previous step). The choice of sweep rate shall allow time for the EUT to respond, taking account of any delay, integration or processing times. During the sweeps with sinusoidal amplitude modulation, the frequency shall not change by more than 1 % of the fundamental frequency in the time required for the EUT to respond or 3 s, whichever is the greater. During the sweeps with pulse modulation, the frequency shall not change by more than 1 % of the fundamental frequency in the time required to switch the continuous wave ON and OFF at least 3 times, at the required rate (see ).
17 IEC: For EUTs with particularly long response times, it may be impractical to sweep at the rate described above due to time constraints. In such cases, it may be possible to increase the required sweep rate to a practical value by applying one or more of the following: by modifying the operation of the EUT to reduce its overall response time (e.g. by implementation of special test modes or software that reduce delays or sampling periods but maintain the main functionality of the EUT); by monitoring EUT parameters, which may reveal malfunctions before the EUT exhibits them to the user/interface; by comparing infrequent functions with frequent functions which have similar operation. In some cases, it may not be possible to detect all possible malfunctions within an acceptable time frame. In such cases, the likelihood and consequences of the malfunctions should be considered and the sweep rate should be agreed by the manufacturer and/or test/certification organization. The EUT shall be subjected to the conditioning in three orientations relative to the field, such that the electric E and magnetic H components of the field are applied in each of three orthogonal axes of the EUT (e.g. see Figure 1). E H P P E H H P E IEC 1000/10 Key E H P electric field vector magnetic field vector propagation vector Figure 1 Example of relative orientations of the EUT and the field vectors Initial examination Before conditioning, subject the specimen to the functional test (see Clause 6) State of specimen during conditioning Connect the specimen to suitable power supply, monitoring and loading equipment (see 5.1).he specimen shall be in its operating condition (see 5.3) Conditioning Apply the severity of conditioning indicated in Table 4:

NOTE This figure is only intended to show the forms and relative amplitudes of the modulation. It does not accurately represent the relative frequencies. Figure 2 Forms of modulation types relative to a continuous wave Measurements during conditioning Monitor the specimen during the conditioning period to detect any change in status Final measurements After conditioning, subject the specimen to the functional test (see Clause 6),and inspect it visually for mechanical damage Criteria for compliance There shall be no damage, malfunction or change of status due to the conditioning. Flickering of an indicator during conditioning is permissible, providing that there is no residual change in the EUT or any change in outputs, which could be interpreted by associated equipment as a change, and no such flickering of indicators occurs at a field strength of 3 V/m. For components of CCTV systems, where the status is monitored by observing the TV picture, then deterioration of the picture is allowed at 10 V/m, providing:
19 IEC: a) there is no permanent damage or change to the EUT (e.g. no corruption of memory or changes to programmable settings, etc.); b) at 3 V/m, any deterioration of the picture is so minor that the system could still be used; and c) there is no observable deterioration of the picture at 1 V/m. For components with radio links, it is accepted that communications via the radio link may not be possible during conditioning within the transmitter and receiver exclusion bands defined in the relevant part of ETSI EN for that type of radio link equipment. If no part of ETSI EN is applicable to the type of radio link equipment, then the definition of the exclusion bands shall be taken from ETSI EN If the EUT is designed to detect and indicate this loss of communication, then this indication is permitted unless specifically prohibited in the EUT s product performance standard. If no performance standard has been published, then it shall be in accordance with the manufacturer's specification. It may be necessary to use appropriate filters to ensure that failures out of the exclusion bands are not due to harmonics generated by the test system. After conditioning, the EUT shall meet the acceptance criteria for the functional test (see Clause 6). 11 Conducted disturbances induced by electromagnetic fields 11.1 Object of the test To demonstrate the immunity of equipment to conducted disturbances induced by electromagnetic fields onto the field wiring (e.g. such as produced by portable radio transceivers, radio telephones etc.) Principle The test consists of injecting radio frequency disturbances, in the frequency range of 150 khz to 100 MHz, onto the various input/output ports of the equipment. The equipment is exposed to both amplitude modulated and pulse modulated (switched CW) signals. The pulse modulated exposure has been added as it has been found by experience that some components of alarm systems are particularly susceptible to pulsed or switched signals Test procedure General The test apparatus and procedure shall be as described in IEC , with the following modifications and clarifications taken into account. Where the frequency range is swept incrementally, the step size shall not exceed 1 % of the fundamental frequency (i.e. the frequency of the previous step). The choice of sweep rate shall allow time for the EUT to respond, taking account of any delay, integration or processing times. During the sweeps with sinusoidal amplitude modulation, the frequency shall not change by more than 1 % of the fundamental frequency in the time required for the EUT to respond or 3 s, whichever is the greater. During the sweeps with pulse modulation, the frequency shall not change by more than 1 % of the fundamental frequency in the time required to switch the CW ON and OFF at least 3 times, at the required rate (see ). For EUTs with particularly long response times, it may be impractical to sweep at the rate described above due to time constraints. In such cases, it may be possible to increase the required sweep rate to a practical value by applying one or more of the following:
20 IEC:2010 by modifying the operation of the EUT to reduce its overall response time (e.g. by implementation of special test modes or software that reduce delays or sampling periods but maintain the main functionality of the EUT); by monitoring EUT parameters, which may reveal malfunctions before the EUT exhibits them to the user/interface; by comparing infrequent functions with frequent functions which have similar operation. In some cases, it may not be possible to detect all possible malfunctions within an acceptable time frame. In such cases, the likelihood and consequences of the malfunctions should be considered and the sweep rate should be agreed by the manufacturer and/or test/certification organization. No test is required for ports intended for supply/signal lines, other than a.c. mains supply lines, where the manufacturer s specification indicates that it is not permitted to connect cables > 3 m long Initial examination Before conditioning, subject the specimen to the functional test (see Clause 6) State of specimen during conditioning Connect the specimen to suitable power supply, monitoring and loading equipment (see 5.1). The specimen shall be in its operating condition (see 5.3). During the test, at least one of each type of input/output shall be terminated via a CDN or appropriate terminating impedance. If the equipment is fitted with more than one input/output of the same type then, when the test signal is being injected into one of these input/outputs, at least one other of the same type shall be terminated with a CDN or appropriate terminating impedance. Where there is insufficient space for all of the CDNs to be within 300 mm of the EUT, then some of the CDNs, not being injected, may be placed more than 300 mm from the EUT, but shall be as close as possible. NOTE The non-excited RF input ports to the CDNs should be terminated by 50 Ω loads Conditioning Apply the severity of conditioning indicated in Table 5: Table 5 Frequency range (MHz) 0,15 to 100 Voltage level (emf) a U 0 (dbμv) (V) 140 (10) Modulation: Amplitude modulation b Pulse modulation b 80 %, 1 khz, sinusoidal 1 Hz (0,5 s ON: 0,5 s OFF) a The voltage level quoted is the open-circuit RMS value for the continuous wave, before modulation. b See Figure Measurements during conditioning Monitor the specimen during the conditioning period to detect any change in status Final measurements After the conditioning, subject the specimen to the functional test (see Clause 6), and inspect it visually for mechanical damage.
21 IEC: Criteria for compliance There shall be no damage, malfunction or change of status due to the conditioning. Flickering of an indicator during conditioning is permissible, providing that there is no residual change in the EUT or any change in outputs, which could be interpreted by associated equipment as a change, and no such flickering of indicators occurs at U 0 = 130 dbμv. For components of CCTV systems, where the status is monitored by observing the TV picture, then deterioration of the picture is allowed at U 0 = 140 dbμv, providing: a) there is no permanent damage or change to the EUT (e.g. no corruption of memory or changes to programmable settings etc.), b) at U 0 = 130 dbμv, any deterioration of the picture is so minor that the system could still be used; and c) there is no observable deterioration of the picture at U 0 = 120 dbμv. For components with radio links, it is accepted that communications via the radio link may not be possible during conditioning within the transmitter and receiver exclusion bands defined in the relevant part of ETSI EN for that type of radio link equipment. NOTE If no part of ETSI EN is applicable to this type of radio link equipment, then the definition of the exclusion bands should be taken from ETSI EN After conditioning, the EUT shall meet the acceptance criteria for the functional test (see Clause 6). 12 Fast transient bursts 12.1 Object of the test To demonstrate the immunity of equipment to bursts of fast low energy transients which may be produced by relays, contactors etc., switching inductive loads and may be induced into signal and data circuits etc Principle The test consists of the injection of bursts of fast transients onto the power supply and/or signal inputs and outputs of the equipment Test procedure General The test apparatus and procedure shall be as described in IEC , using the test procedures for type tests performed in laboratories Initial examination Before conditioning, subject the specimen to the functional test (see Clause 6) State of specimen during conditioning Connect the specimen to a suitable power supply, monitoring and loading equipment (see 5.1). The specimen shall be in its operating condition (see 5.3) Conditioning Apply the severity of conditioning indicated in Table 6:

Applied by the capacitive clamp injection method. No test is required where the manufacturer s specification indicates that it is not permitted to connect cables > 3 m long Measurements during conditioning Monitor the specimen during the conditioning period to detect any change in status Final measurements After conditioning, subject the specimen to the functional test (see Clause 6), and inspect it visually for mechanical damage Criteria for compliance There shall be no damage, malfunction or change of status due to the conditioning. Flickering of an indicator during the application of the bursts is permissible, providing that there is no residual change in the EUT or any change in outputs which could be interpreted by associated equipment as a change. After conditioning, the EUT shall meet the acceptance criteria for the functional test (see Clause 6). 13 Slow high energy voltage surge 13.1 Object of the test To demonstrate the immunity of equipment to relatively slow high energy transients, which may be induced in power and signal cables from lightning strikes in the vicinity or by switching in the power distribution system or the low voltage network, including the switching of large capacitor batteries Principle The test consists of the injection of slow high energy transients into the a.c. mains supply lines in both line-to-line and line-to-ground coupling mode, and into the signal and extra low voltage supply lines in line-to-ground coupling mode. The impedance of the transient generator (effectively 2 Ω) is characterized by the shape (i.e. amplitude, rise time and decay time) of the open-circuit voltage and the short-circuit current pulses. To simulate typical installation impedances, 40 Ω is inserted in series with the generator when extra low voltage and signal lines are tested, and 10 Ω is inserted when the line-to-ground test is conducted on the a.c. mains lines.
23 IEC: The test pulses are coupled into the leads to be tested by means of appropriate coupling networks, which maintain the test pulses within their specification Test procedure General The test apparatus and procedure shall be as described in IEC , with the following modifications and clarifications taken into account. The EUT shall be arranged and connected in accordance with the manufacturer's installation instructions. Apart from the manufacturer's specified earth connections, the EUT and interconnecting cables shall be insulated from the ground reference. AC mains power lines shall be subjected to transients injected by both line-to-line and line-toground coupling modes. With line-to-ground coupling, the transients shall be injected via a 10 Ω series resistor. The length of the power lines between the EUT and the coupling/decoupling network shall be 2 m. At least 20 pulses of each polarity shall be applied at each of the voltage levels shown for the appropriate severity. These pulses shall be synchronized with the mains voltage wave such that at least 5 pulses are applied at each of the zero crossing points and at the maximum and minimum points. The pulses may be applied at a maximum rate of 1 per 5 s. However, it is necessary to ensure that any failures are not due to applying the pulses too frequently, and that if this is not clear, then the failed devices should be replaced and the test repeated with the pulses applied at a rate of less than 1/min. Extra low voltage and signal lines shall be subjected to transients injected by line-to-ground coupling mode only, via a 40 Ω series resistor. If the equipment has a large number of identical inputs/outputs (e.g. detector loops), then representative samples of each type of input/output may be selected for testing. The length of the signal lines between the EUT and the coupling/decoupling network(s) shall be 2 m. However, if it is specified in the manufacturer s data that certain signal lines shall only be connected with screened cables, then in these cases, the transients shall be applied directly (i.e. without the 40 Ω series resistor) to the screen of a 20 m length of screened cable as shown in Figure 3. Current compensated chokes may be used to decouple signal lines carrying high frequency signals, to reduce the problems of attenuation. At least 5 pulses of each polarity shall be applied at each of the voltage levels shown for the appropriate severity. The pulses may be applied at a maximum rate of 1 per 5 s. However, it is necessary to ensure that any failures are not due to applying the pulses too frequently and that if this is not clear, then the failed devices should be replaced and the test repeated with pulses applied at a rate of less than 1/min.
