3.1
)
element of electrical or optical connection
component such as connector, module, etc., the purpose of which is to ensure the connection of circuits
3.2
flight cover (or protective cover)
accessory designed to ensure, in flight, mechanical protection and sealing of front face of a non-coupled
connector
3.3
connector with built-in protection of contacts
connector with characteristics such that male or female contacts, mounted in a plug or receptacle,
cannot come into contact with the front of the connector to which it is coupled (scoop-proof) and in
which, in the event of accidental coupling of two parts or the connector equipped with male contacts, no
electrical contact can take place
3.4
contact pressure point
point at which a square ended gauge pin of the same basic diameter as the mating contact first engages
the female contact spring member
3.5
initial measurement
examination or measurement of characteristics carried out to determine the magnitude of the
variations produced by the stress or stresses applied
This examination or measurement is carried out at the end of pre-conditioning and under normal
atmospheric conditions for measuring
3.6
final measurement
examination or measurement of characteristics carried out at the end of the recovery to assess the
condition of the specimen after testing and to determine the magnitude of the variations in
characteristics in relation to the values recorded at initial measuring
3.7
flammability
a product is considered to be “non-flammable” when combustion due to exposure for a given duration
to a standard external flame remains localized and stops spontaneously after withdrawal of the flame
5)
In test standards the term "element of connection" shall be used.

prEN 2591-100:2022 (E)
3.8
fire resistance
a product is considered to be “fire-resistant” when, subjected to a standard flame:
— it retains its electrical role for six minutes;
— the flame does not propagate to the other side of the support in the first twenty minutes
3.9
values of alternating voltage and current
unless otherwise indicated, alternating voltage and current are indicated in root mean square values
3.10
line data bus
pair of twisted wires, shielded, having a specified impedance, a matched impedance at its two ends and
used for data transport
3.11
branch line
section of twisted wires, shielded, with a specified impedance, which connects equipment to a bus line

coupler consisting of one line and one branch
3.14
line coupler, double
coupler consisting of one line and two branches
3.15
in-line splice
permanent element of electrical or optical connection for two-wire cables
3.16
line termination
end line component the purpose of which is to match the bus line to its characteristic impedance
3.17
branch termination
end branch termination the purpose of which is to eventually replace equipment
3.18
recovery
treatment of a specimen, after conditioning, so that the properties of the specimen may be stabilized
before measuring
3.19
optical fibre cable
certain number of optical fibres or bundles, coated separately and joined inside a common sheath
