This document (EN 50411-2-4:2021) has been prepared by CLC/TC 86BXA, “Fibre optic interconnect,
passive and connectorised components”.
The following dates are fixed:
• latest date by which this document has to be (dop) 2022-05-26
implemented at national level by publication of
an identical national standard or by
endorsement
• latest date by which the national standards (dow) 2024-11-26
conflicting with this document have to be
withdrawn
This document supersedes EN 50411-2-4:2012 and all of its amendments and corrigenda (if any).
EN 50411-2-4:2012:
— reference EN IEC 61756-1 is added;
— terms and definitions are added;
— harmonized general requirements with the EN IEC 61753-111 series;
— the IEC 61753-1:2007 categories A and S tests and test severities are replaced by the
IEC 61753-1:2018 categories A and S tests and test severities;
— maximum single circuit splice capacity of size E closure reduced from 84 splices to 72 splices;
— variant XX (FMS designed for fibre type) added;
— test pressure for category A changed to 20 kPa overpressure;
— reduced loads in cable retention test for small diameter cables and tubes;
— axial compression test of cables is added;
— number of assembly and disassembly cycles reduced to 5 cycles;
— resistance to solvents and contaminating fluids for category S has changed. The duration of the
immersion in diesel became 1 h and the drying time 24 h. Immersion in kerosene is removed;
— duration of the change of temperature reduced to 12 cycles;
— the test “resistance to shot gun blasts” test is removed;
— fibre type B-567 added for test sample.

1 Scope
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. T
