PASSIVE COMPONENTS – BASIC TEST AND MEASUREMENT PROCEDURES – Part 2-34: Tests – Resistance to solvents and contaminating fluids of interconnecting components and closures Scope The purpose of this part of IEC 61300 is for testing fibre optic interconnecting components and closures The object of this test is to define a standard test method to assess the effects of short term exposure to fluids and lubricants on fibre optic interconnecting components and closures 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 IEC 61300-1, Fibre optic interconnecting devices and passive components – Basic test and measurement procedures – Part 1: General and guidance General description This test method covers the effects of contaminating fluids on the properties of fibre optic interconnecting components and closures Testing is performed by immersing specimens in a specified fluid for a specified period at a specified temperature A separate specimen shall be used with each fluid Properties are measured prior to and after exposure to the fluid WARNING − Intended users of this procedure are cautioned that tests of this nature may involve the use of certain hazardous material, operations and equipment In particular, some of the fluids that may be used are flammable or may constitute health hazards, or both Test temperatures should be at least 10 °C below the flashpoint of any fluid being used Open flame heat sources should not be used with any organic solvents Test personnel should consult the relevant material’s safety data sheets when necessary 4.1 Apparatus Containers A boro-silicate glass or stainless steel vessel of suitable volume for each test fluid shall be used Vessels shall be of sufficient size and capacity to permit the specimen to be immersed until it is fully covered in the selected fluid without violating other physical constraints (e.g minimum cable bend radius) 4.2 Fluids Fluids used shall be in accordance with the relevant specification for the fluid BS EN 61300-2-34:2009 –6– Licensed copy: Bradford University, University of Bradford, Version correct as of 21/03/2012 14:28, (c) The British Standards Institution 2012 4.3 61300-2-34 © IEC:2009(E) Heat source A suitable heat source capable of achieving and maintaining the specified temperatures within ±2 °C of the required setting shall be used 4.4 Oven A suitable oven to dry the specimen shall be used 5.1 Procedure General The preparation of the specimen shall be in accordance with the relevant specification If cables are fitted they must be long enough to exit the test medium Where no cables are fitted blanking plugs must be inserted 5.2 Preconditioning Clean the mechanical and optical alignment parts of the specimen according to the manufacturer’s instructions Unless otherwise stated, maintain the specimen under standard atmospheric condition according to IEC 61300-1 for h minimum 5.3 Initial examinations and measurements If specified, perform initial examinations and measurements as required by the relevant specification 5.4 Conditioning For each specified fluid, prepare a vessel with sufficient fluid such that the specimen can be adequately immersed Immerse the specimen for the specified period while maintaining the fluid temperature NOTE In the case of volatile fluids, it may be necessary to add additional amounts of fluid (heated to the test temperature) during the test in order to keep the specimen immersed 5.5 Recovery At the end of the immersion period, remove the specimen and wipe off surplus fluid Where applicable as defined in the relevant specification, dry components in an oven at an appropriate temperature for a defined period 5.6 Final examinations and measurements Upon completion of the test, the specimen(s) shall be examined and all necessary observations recorded as specified in the relevant specification Careful attention shall be given to swelling of materials, loss of adhesive bonding between bonded surfaces, corrosion of materials, softening of materials, cracks in material, degradation of optical characteristics, etc The functional measurements shall be accomplished at the standard test conditions as defined in IEC 61300-1, unless otherwise specified in the relevant specification BS EN 61300-2-34:2009 61300-2-34 © IEC:2009(E) Licensed copy: Bradford University, University of

fluid temperature The severity shall be specified in the relevant specification The following preferred severities are non-mandatory severities which may be specified for this procedure 6.2 Exposure and drying duration Specimen shall be exposed to the test for the following preferred duration: Table – Preferred test durations 1h 24 h days days month After exposure specimen shall be recovered by drying applied according to the temperatures given in the relevant specification and durations mentioned below Table – Preferred drying durations 1h 2h 24 h The dry out temperature should be at maximum temperature of the service environment 6.3 Fuels, lubricants, hydraulic fluids, cleaning agents and moisture repellents and anti-freeze agents Table provides a non exhaustive list of
