2、een prepared under the direction of the Electrokchnicai Sector Board, was published under the authority of the Standards Board and comes into effect on 15 February 1998 Date Text affected O BSI 1998 National foreword This British Standard is the English language version of EN 186290 : 1997 published
3、 by the European Electronic Components Committee (CECC) of the European Committee for Electrotechnid Standardization (CENELEC). The UK participation in its preparation was entrusted by Technical Committee EPM6, Fibre optics, to Subcommittee EPL/86/2, Interconnecting devices and passive components, w
4、hich has the responsibility to: - aid enquirers to understand the tea - present to the responsible internationalEuropean committee any enquiries on the interpretation, or propods for change, and keep the UK interests informed; - monitor related international and European developments and promulgate
5、them in the UK. A list of organizations represented on this subcommittee can be obtained on request to its secretary. Cross-references Attention is drawn to the fact that CEN and CENELEC standards normally include an annex which lists normative references to international publications with their cor
6、responding European publications. The British Standards which implement these intedonal or European publications may be found in the BSI Stan but sufficient information should be made available in the manufacturers literature to enable the system designer to assess the degree of hazard. This informa
7、tion shall be given prominence in the detail specification (W. 1.4.2 The assembly instructions, included in the connector package, shall give a prominent warning to the assembler, of the necessary safe work practices. 1.4.3 The responsibility for the safe application of the connector lies with the s
8、ystem design engineer, who should refer to IEC 825. As there is no safety guide for light emitting diodes (LEDs), IEC 825 shall apply to systems using these also. 1.4.4 DSs should give the following information in a prominent position:- WARNING “Care should be taken when handling small diameter opti
9、cal fibre, to prevent it puncturing the skin especially in the eye area. Direct viewing of the end of an optical fibre or a terminated optical fibre, while it is propagating energy is not recommended unless prior assurance has been obtained as to the safe energy of the output level.“ 1.5 Marking See
