ELECTROTECHNICAL COMMISSION FIBRE OPTIC INTERCONNECTING DEVICES AND PASSIVE COMPONENTS – BASIC TEST AND MEASUREMENT PROCEDURES – Part 2-9: Tests – Shock 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 61300-2-9 has been

to entry A number of check points may be used to ensure the test requirements are satisfied Note to entry If the DUT is attached by more than four fixing points, the relevant specification should state the number of fixing points that are to be used as check points BS EN 61300-2-9:2017 IEC 61300-2-9:2017 © IEC 2017 –6– Note to entry In special cases, for example, for large or complex DUTs, the check points will be prescribed by the relevant specification Note to entry If a small DUT is mounted on one fixture or a large number of small DUTs are mounted on one fixture, or where there are a number of fixing points, a single check point (that is the reference point) may be selected for the derivation of the control signal This signal is then related to the fixture rather than to the fixing points of the DUT(s) This procedure is only valid when the lowest resonance frequency of the loaded fixture is well above the upper frequency of the test 3.2 fixing point point on the DUT in contact with the fixture (Figure 1a) or the table of the shock machine at a location where the DUT is normally fastened in service Note to entry If a part of the real mounting structure is used as the fixture, the fixing points are taken as those where the real mounting structure contacts the table (Figure 1b) and not where the product contacts the real mounting structure DUT Fixing points Fixture

device under test (DUT) is mounted on the table of the shock machine and is subjected to half-sinusoidal shock pulses The DUT is exposed to two or three shock pulses applied in each direction of three mutually perpendicular axes in accordance with severities (see Clause 7) Wherever possible, the severity of the pulse applied to the DUT should be such as to reproduce the effects of the actual transport or operational environment to which the DUT will be subjected, or to satisfy the design requirements The DUT is always mounted to the fixture or the table of the shock machine during testing Apparatus 5.1 Shock machine 5.1.1 General The shock machine may be of the free fall, resilient rebound, nonresilient, hydraulic, compressed gas or other activating type The shock machine shall be capable of generating a calibrated acceleration when loaded with a DUT, with or without a fixture The shock machine shall be capable of generating a half-sinusoidal excitation measured at the checkpoints, within the tolerance shown by the solid lines in Figure Integration time 1,5 D Acceleration (relative value) 1,2 A A 0,8 A +0,2 A 0,2 A 0,2 A –0,2 A –0,2 A 0,1 D 0,4 D D 2,5 D D 2,5 D 2,4

conventional shock machine D= duration of nominal pulse T2 = minimum time during which the pulse shall be monitored for shocks produced using a vibration generator Figure – Pulse shape and limits of tolerance for half-sine pulse –8– 5.1.2 BS EN 61300-2-9:2017 IEC 61300-2-9:2017 © IEC 2017 Repetition rate The repetition rate shall be such that the relative motion within the DUT between shocks shall be substantially zero and the value of acceleration at the check point shall be within the limits shown in Figure 5.1.3 Velocity change tolerances For all pulse shapes, the actual velocity change shall be within ±15 % of the value corresponding to the nominal pulse Where the velocity change is determined by integration of the actual acceleration pulse, this shall be effected from 0,4 D before the pulse to 0,1 D beyond the pulse, where D is the duration of the nominal pulse If the velocity change tolerance cannot be achieved without the use of elaborate facilities, the relevant specification shall state the alternative procedure to be adopted 5.1.4 Cross axis motion The positive or negative peak acceleration at the check point(s), perpendicular to the intended shock direction, shall not exceed 30 % of the value of the peak acceleration of the nominal pulse in the intended direction, when determined by 5.1.5 If the cross axis motion tolerance cannot be achieved, the relevant specification shall state the alternative procedure to be adopted 5.1.5 Acceleration measuring system The characteristics of the measuring system shall be such that it can be determined that the true value of the actual pulse, as measured above, in the intended direction at the checkpoint(s) is within the tolerances required by Figure The requirements of Figure apply to the frequency response of the measuring system without the use of a low-pass filter on the control signal When a low-pass filter is used, the characteristics of the filter should be such that its cut-off frequency fg (–3 dB point) is not lower than: fg = 1,5 D where fg is the cut-off frequency of a low-pass filter in kHz; D is the duration of nominal pulse in ms The frequency response of the overall measuring system, which includes the accelerometer, can have a significant effect on the accuracy and shall be within the limits shown in Figure and Table BS EN 61300-2-9:2017 IEC 61300-2-9:2017 © IEC 2017 –9–

monitoring the transient loss to detect fast variation of attenuation 6.1 Procedure Preparation of DUT Prepare the DUT according to the manufacturer´s instructions or as specified in the relevant specification – 10 – 6.2 BS EN 61300-2-9:2017 IEC 61300-2-9:2017 © IEC 2017 Pre-conditioning Pre-condition the DUT for h at the standard atmospheric condition specified in IEC 61300-1 unless otherwise specified in the relevant specification 6.3 Initial examinations and measurements Complete initial examinations and measurements of the DUT as required by the relevant specification 6.4 Testing The DUT shall be mounted rigidly to the fixture in a manner that simulates normal mounting as closely as possible A minimum length of 200 mm of optical fibre/cable shall be unsupported on both ends of the DUT and be attached free of tension to the table of a shock machine Conduct the procedure as outlined in 6.5 and 6.6 The number of shocks prescribed by the relevant specification shall be applied successively in each direction of three mutually perpendicular axes of the DUT When testing a number of identical DUTs, they may be oriented so that the shocks are applied simultaneously along these three axes (see Clause 7) Where the position of the DUT, when mounted or transported, is known, and since shocks are generally of greatest significance in one direction of one axis, the relevant specification shall state the specified number of shocks that shall be applied and in which axis, direction and position Otherwise, three axes and two directions shall be tested For example, usually the highest levels of shock acceleration are along the vertical axis When the position during transportation is known, the shocks should be applied in what will be the vertical axis in the upward direction Where the position is unknown, the specified number of shocks shall be applied in each of the axes prescribed by the relevant specification (see Clause 7) The relevant specification shall state whether the DUT shall operate during testing and if any functional monitoring is required 6.5 Recovery Allow the DUT to remain on the fixture for unless otherwise specified in the relevant specification 6.6 Final examination and measurements On completion of the test, remove all fixtures, clean the DUT in accordance with the manufacturer’s instruction and inspect the DUT and make final measurements as defined by the relevant specification, to ensure that there is no permanent damage to the DUT The relevant specification shall provide the criteria upon which the acceptance or rejection of the DUT shall be based Unless otherwise specified, visually examine the DUT in accordance with IEC 61300-3-1 Check for evidence of any degradation in the DUT This may include, for example • broken, loose or damaged parts and/or accessories, • broken or damaged cable sheath, seals, strain relief or fibres, and • displaced, bent, broken or damaged parts BS EN 61300-2-9:2017 IEC
