1.1 Product definition This document contains the initial, start of life dimensional, optical, mechanical and environmental performance requirements of a fully installed splice closure in order for it to be categorized as a European Standard product. 1.2 Operating environment The tests selected combined with the severity and duration are representative of an outside plant for subterranean and/or aerial environments defined by: EN IEC 61753-1 category S: subterranean environment category A: aerial environment 1.3 Reliability Whilst the anticipated service life expectancy of the product in this environment is 20 years, compliance with this specification does not guarantee the reliability of the product. This is predicted using a recognized reliability assessment programme. 1.4 Quality assurance Compliance with this specification does not guarantee the manufacturing consistency of the product. This is maintained using a recognized quality assurance programme. 1.5 Allowed fibre and cable types This closure standard allows both single-mode and multi-mode fibre to be used and covers all IEC standard optical fibre cables with their various fibre capacities, types and designs. This includes, but is not limited to, optical fibre cable standards EN 60794 2 (indoor) and EN 60794-3 (outdoor). The optical performance tests are carried out on test samples with EN IEC 60793-2-50 single-mode fibre (see Annex A). The selected fibre type for the optical test samples depends on the design of the fibre management system.
