1.1Product definition This specification 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 categorised as an EN standard product. 1.2Operating environment The tests selected combined with the severity and duration is representative of outside plant for subterranean and/or aerial environments defined by: ETSI EN 300 019-1-4class 8.1: underground locations (without earthquake requirement) EN 61753-1 category S: subterranean environment category A: aerial environment 1.3Reliability 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 should be predicted using a recognised reliability assessment programme. 1.4Quality assurance Compliance with this specification does not guarantee the manufacturing consistency of the product. This should be maintained using a recognised quality assurance programme. 1.5Allowed fibre and cable types Although the performance tests are carried out on test samples with dispersion un-shifted singlemode fibre (see Annex A), the closure, once tested according to this product specification, will be also suited for other fibre types like dispersion shifted, non-zero dispersion shifted and multimode fibres. This closure standard allows both singlemode and multimode fibre to be used and covers all EN 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), EN 60794-3 (outdoor).
