12、EN 186260: 1997 1 General 1.1 Scope This sectional specification covers a family of single way fibre optic connector sets which are classified as type SC. Type SC is a connector set of the plug-adaptor-plug configuration. It features a push-pull coupling mechanism and cylindrical butting ferrules. T

13、he optical alignment mechanism is a split sleeve contained within the adaptor. The specification contains the requirements for type SC connector sets. Detail specifications (DSs) shall be prepared using the following pro forma general blank detail specifications (BDSs) associated with the generic sp

14、ecification. For example: - EN 166005 for environmental category V. When completed, the DS(s) applicable to this SS shall be numbered in accordance with CECC O0 700 (Section IV) Issue I, clause 4.2. as follows. For example: - CECC 66 265-000, Type sc, environmental category V. I .2 Related documents

The manufacturers of connectors are not obliged to mark them as such, but sufficient information should be made av

19、ailable in the manufacturers literature to enable the system designer to assess the degree of hazard. This information shall be given prominence in the detail specification (DS). 1.4.2 The assembly instructions, included in the connector package, shall give a prominent warning to the assembler, of t

20、he necessary safe work practices. 1.4.3 The responsibility for the safe application of the connector lies with the system design engineer, who should refer to IEC 825- I. As there is no safety guide for light emitting diodes (LEDs), IEC 825-1 shall apply to systems using these also. 1.4.4 DSs should

21、 give the following information in a prominent position : WARN IN C “Care should be taken when handling small diameter optical fibre, to prevent it puncturing the skin, especially in the eye area.
