28、 performance requirements which a terminated and assembled singlemode resilient alignment sleeve LSH-APC simplex connector set (plug/adaptor/plug), adaptor and patchcord must meet in order to be categorised as an EN standard product. Since different variants and grades of performance are permitted,
29、product marking details are given in 3.5. 1.2 Intermateability Although all products conforming to the requirements of this standard will intermate, the resulting level of random attenuation performance will only be ensured in accordance with Table 1. The intention is that this will be true irrespec
30、tive of the manufacturing source(s) of the product. When intermating plug variants having different attenuation grades, the resulting level of attenuation can not be assured to be any better than the worst attenuation grade. The intermating of a grade C plug with a grade B plug will result in an unc
31、ertain level of random attenuation performance.

32、. 1.4 Reliability Whilst the anticipated service life expectancy of the product in this environment is 20 years, compliance with this standard does not guarantee the reliability of the product. This should be predicted using a recognised reliability assessment programme. 1.5 Quality assurance Compli
33、ance with this standard does not guarantee the manufacturing consistency of the product. This should be maintained using a recognised quality assurance programme.
