OPTIC INTERCONNECTING DEVICES AND PASSIVE COMPONENTS – BASIC TEST AND MEASUREMENT PROCEDURES – Part 2-12: Tests – Impact Scope This part of IEC 61300 is to evaluate the ability of a passive fibre optic device or a closure to withstand impacts likely to be encountered during usage The impact may be a localized impact, a series of impacts with hard objects, or an impact normally associated with dropping the device Normative references The following referenced documents are indispensable for the application of this document For dated references, only the edition cited applies For undated

methods are described: – Method A: a specimen with an attached length of cable is freely swung in a pendular motion and allowed to strike an impact surface – Method B: a steel ball is dropped on the specimen which is placed on a smooth hard rigid surface of concrete or steel – Method C: the specimen is released such as to allow free fall drops from the position of suspension Impairment of function to the extent that the device fails to meet the requirements of the relevant specification constitutes failure Apparatus 4.1 4.1.1 Method A – Pendulum drop Attaching fixture The attaching fixture shall be capable of being mounted on any convenient, rigid, vertical structure If the device has an attached cable, the cable shall be mounted to the fixture in such a manner as to allow it to swing freely from a horizontal to a vertical position An BS EN 61300-2-12:2009 EN 61300-2-12:2009 (E) –6– Licensed copy: Bradford University, University of Bradford, Version correct as of 21/03/2012

shall be positioned on a smooth hard rigid surface of concrete or steel Where necessary, other surfaces may be defined in the relevant specification 4.2.3 Drop apparatus An example of an apparatus to drop the impact tool is given in Figure It consists of a hollow tube (guide) with a release system The inner diameter of the tube shall be wide and smooth enough to minimise interaction between the tube and impact tool during the free fall BS EN 61300-2-12:2009 EN 61300-2-12:2009 (E) –7– Licensed copy: Bradford University, University of Bradford, Version correct as of 21/03/2012 14:27, (c) The
