1 Scope
Product definition
This specification contains the initial, start of life dimensional, mechanical and environmental performance
requirements which an unprotected microduct must meet. It does not address the installation capability of
these products which must be agreed between the user and supplier.
Operating environment
The tests selected combined with the severities and duration are representative of an outside plant for
subterranean and/or aerial environment defined by:
— ETS 300 019 : class 8.1: underground locations (without earthquake requirement)
— EN 61753-1 : category S: subterranean environment, category A: aerial environment
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.
Allowed product types
This standard covers all European Standard on optical fibre unprotected microducts. This includes, but is
not limited to, EN 60794-5, Optical fibre cables - Part 5: Sectional specification - Microduct cabling for
installation by blowing.
Allowed microduct connector types
This microduct standard allows the use of all European Standard on microduct connectors, including:
straight, reducer/enlarger stem, reducer/enlarger, close down, liquid block, liquid block with barb end, and
end stop connectors. This includes EN 50411-2-8, Fibre organisers and closures to be used in optical
fibre communication systems - Product specifications - Part 2-8: Microduct connectors, for air blown
optical fibres, Type 1.

3 Terms, definitions and abbreviations
3.1 Terms and definitions
3.1.1
unprotected microduct
small, flexible, lightweight tube with an outer diameter typically less than or equal to 16 mm
NOTE Unprotected microducts are designed to be contained within a loose or tight outer layer to form a protected
microduct.
3.1.2
protected microduct
one or more microducts surrounded by a protective sheath and/or protected by a duct/sub-duct
NOTE Alternatively a microduct may be regarded as protected if it has a sufficiently high wall a thickness.
3.1.3
microduct optical fibre cable
optical fibre cable suitable for installation by blowing into a microduct
3.1.4
microduct fibre unit
fibre unit that is suitable for installation by blowing into a microduct
NOTE It differs from microduct optical fibre cables in that it provides less protection to the fibres that it contains.
3.1.5
burst pressure
point at which the microduct fails to contain pressure
3.1.6
low friction surface
smooth or ribbed internal layer with the purpose to reduce the friction coefficient between microduct and
cable/fibre unit
3.1.7
anti static surface
internal layer with the purpose to reduce the antistatic forces between the microduct and the cable/fibre
unit
