IEC:2012 –5– FIBRE OPTIC INTERCONNECTING DEVICES AND PASSIVE COMPONENTS – BASIC TEST AND MEASUREMENT PROCEDURES – Part 2-11: Tests – Axial compression Scope The purpose of this part of IEC 61300 is to ensure that the captivation or the attachment of the cable to the fibre optic devices such as fibre optic closures will withstand compressive axial loads likely to be applied during normal service

applying an axial compression load between a clamped specimen and a cable The apparatus consists of the elements described in 4.2 to 4.5 4.2 Clamping device A suitable clamping device which grips a length of fibre optic cable over a distance equivalent to at least three times the cable diameter (see Figure 1, Dimension A), and which is capable of providing an axial load without slipping, causing damage to the cable or increasing attenuation 4.3 Fixed clamping device A fixed clamping device capable of gripping the specimen without altering any of its mechanical properties BS EN 61300-2-11:2013

under test to the fixed clamping device See Figure for an example of the test set-up Clamp the cable at the point of application using a clamping device such that the distance, L, between the rear of the strain relief and the front of the cable clamping device is twice the cable diameter The length, L, shall be at maximum two times the cable diameter to prevent cable buckling A L IEC 2023/12 Key fixed clamping device device under test strain relief fibre optic cable clamping device Figure – Example of test apparatus 5.4 Apply load Smoothly apply the axial compressive load to the cable, as recommended in Table Unless otherwise specified, maintain the load for a minimum of The position of the point of application shall be such that the load is axially transmitted BS EN 61300-2-11:2013

and its component parts in accordance with IEC 61300-3-1 Check for evidence of cracking, permanent deformation or other damage which might impair its function, and against any other pass/fail criteria specified in the relevant specification Careful attention shall be given to degradation of the optical signal, fibre breakage and excessive movement of the cable relative to the specimen Severity The severity consists of the magnitude of the axial compressive force The severity shall be specified in the relevant specification Recommended values of the test parameters are given in Table and Table
