The test procedures simulate the following conditions which may be encountered during the components servi
27、ce lifetime: the ability of an optical mechanical splice to be re-installed after disassembly; the ability to re-enter fibre management systems and closures, by accessing fibres and optical components and making reconfigurations without disturbing transmission in adjacent fibre circuits; verificatio
28、n of the sealing performance after frequent opening and closing of enclosures. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

Procedure A tests the a
33、bility of optical mechanical splices to be re-installed after disassembly. Procedure B tests the ability to re-enter fibre management systems and closures, by accessing fibres and optical components and making reconfigurations without disturbing transmission in adjacent fibre circuits. Procedure C v
34、erifies the sealing performance after frequent opening and closing of enclosures. The mechanical splice, fibre management system or (en)closure shall be assembled and reassembled a specified number of times following the manufacturers instructions, including any specified cleaning or recovery proced
35、ure. The test shall be done according to requirements referenced in IEC 61753-1. Assembly and disassembly of the mechanical splice, fibre management system or closure shall be carried out at room temperature, unless otherwise specified. 5 Procedure 5.1 Preparation of the specimen Assembly tools and
36、consumable materials, as specified by the manufacturer, shall be used. 5.2 Test procedures 5.2.1 Procedure A: Re-installation of an optical mechanical splice after disassembly General description of the steps for Procedure A is defined as follows. 1) Assemble the mechanical splice according to the m
37、anufacturers installation instructions using the specified fibre or cable. 2) Perform any required examination and measurements as specified in the relevant performance standard. 3) Perform the temperature ageing cycle as specified in the relevant performance standard. When not specified, the ageing
38、 cycle as defined in Table 1 shall be used. After the ageing cycle allow the specimen to recover at ambient temperature for at least 2 hours. 4) Disassemble the mechanical splice to the specified extent or to the point that all internal fibres and devices can be accessed or removed. 5) Perform any s
39、pecified cleaning and fibre preparation operations. 6) Re-install the mechanical splice according to the manufacturers instructions. 7) Perform any required examinations and measurements as specified in the relevant specification. 8) Repeat steps 3 through 7 for the number of cycles specified. 5.2.2
40、 Procedure B: Optical stability during product reconfiguration General description of the steps for Procedure B is defined as follows. BS EN 61300-2-33:201261300-2-33 IEC:2012(E) 7 1) Assemble the (en)closure or fibre management system according to the manufacturers instructions using the specified
41、fibre or cable. An optical circuit is built as specified in the performance standard. 2) Perform any required examination and measurements as specified in the relevant performance standard. The change in attenuation in the optical circuit shall be measured with the transient loss procedure, IEC 6130
42、0-3-28, when performing steps 3, 4 and 5. 3) The handling operations shall be performed as specified in the performance standard (see Annex A for a typical example). The (en)closure shall be disassembled to the specified extent or to the point that the internal fibres and devices can be accessed or
43、removed. 4) Perform the specified reconfiguration operations. 5) Close and secure the fibre management system and reassemble the (en)closure according to the manufacturers instructions. 5.2.3 Procedure C: Sealing performance after frequent opening and closing of the enclosures General description of
44、 the steps for Procedure C is defined as follows. 1) Assemble the (en)closure according to the manufacturers installation instructions using the specified fibre or cable. 2) Perform any required examination and check sealing performance as specified in the relevant performance standard. 3) When spec
45、ified in the performance standard, perform the specified temperature ageing cycle. After the ageing cycle, allow the (en)closure to recover at ambient temperature for at least 4 hours. 4) Disassemble the (en)closure to the specified extent or to the point that all internal fibres and devices can be
46、accessed or removed. 5) Re-install the (en)closure according to the manufacturers installation instructions. 6) Perform any required examinations and check sealing performance as specified in the relevant specification. 7) Repeat steps 3 through 6 for the number of cycles specified. 5.2.4 Ageing pro
47、cedure If specified in the relevant performance standard, the product shall be submitted to an aeging process between assembly and disassembly operations. The major reason for the ageing process is to speed up the creep of the polymeric materials in the alignment area or sealing area after a re-entr
48、y is completed. The purpose of the ageing procedure includes: identification of the design failures; identification of manufacturing defects; impact of product ageing on assembly and disassembly. Table 1 shows ageing conditions. The ageing conditions are based on the operating environmental conditio
49、ns given in IEC 61753-1.
