1 Scope
1.1 Product 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.
1.2 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:
ETS 300 019 class 8.1: underground locations (without earthquake requirement)
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 should be predicted using a
recognised reliability assessment programme.
1.4 Quality assurance
Compliance with this specification does not guarantee the manufacturing consistency of the product. This
should be maintained using a recognised quality assurance programme.
1.5 Allowed fibre and cable types
Although the performance tests are carried out on test samples with dispersion unshifted 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 multi-mode fibres
This closure standard allows both singlemode and multimode 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 IEC 60794-2 (indoor), IEC 60794-3 (outdoor).
