3 Definitions
For the purposes of this standard the following definitions apply.
NOTE Where the terms “voltage” and “current” are used, they imply r.m.s. values unless otherwise specified.
indicator light unit
device equipped with terminals or terminations (such as connecting leads), designed to give a visible signal by light emission, not designed for lighting as a luminaire
3.2
terminal with screw clamping
terminal intended for the connection, by clamping only, of external rigid or flexible conductors
3.3
pillar terminal
terminal with screw clamping in which the conductor is inserted into the hole or cavity, where it is clamped under the end of the screw or screws. The clamping pressure may be applied directly by the end of the screw or through an intermediate clamping member to which pressure is applied by the end of the screw
NOTE Examples of pillar terminals are shown in Figure 1.
3.4
screw terminal
terminal with screw clamping in which the conductor is clamped under the head of the screw. The clamping pressure may be applied directly to the head of the screw or through an intermediate part, such as a washer, clamping plate or anti-spread device
NOTE Examples of screw terminals are shown in Figure 2.
3.5
stud terminal
terminal with screw clamping in which the conductor is clamped under a nut. The clamping pressure may be applied directly by a suitably shaped nut or through an intermediate part, such as a washer, clamping plate or anti-spread device
NOTE Examples of stud terminals are shown in Figure 2.
3.6
mantle terminal
terminal with screw clamping in which the conductor is clamped against the base of a slot in a threaded stud by means of a nut. The conductor is clamped against the base of the slot by a suitably shaped washer under the nut, by a central peg if the nut is a cap nut, or by equally effective means for transmitting the pressure from the nut to the conductor within the slot
NOTE Examples of mantle terminals are shown in Figure 3.
3.7
screwless terminal
connecting device for the connection and subsequent disconnection of a rigid (solid or stranded) or flexible conductor or the interconnection of two conductors capable of being dismantled, the connection being made, directly or indirectly, by means of springs, parts of angled, eccentric or conical form, etc, without special preparation of the conductor concerned, other than removal of insulation
3.8
thread-forming screw
tapping screw having an uninterrupted thread which, by screwing in, forms a thread by displacing material
NOTE An example of a thread-forming screw is shown in Figure 4.
3.9
thread-cutting screw
tapping screw having an interrupted thread which, by screwing in, forms a thread by removing material
NOTE An example of a thread-cutting screw is shown in Figure 5.
3.10
base
part of the indicator light unit retaining current-carrying parts and the mechanism if any, in position
rated voltage
voltage assigned to the indicator light unit by the manufacturer
3.12
rated power
power of the indicator light unit equipped with the lamp(s) assigned by the manufacturer
4 General requirements
Indicator light units and boxes shall be so designed and constructed that, in normal use, their performance is reliable and without danger to the user or the surroundings.
Compliance is checked by meeting all the relevant requirements and tests specified.
5 General notes on tests
5.1 Tests according to this standard are type tests.
5.2 Unless otherwise specified, the specimens are tested as delivered and under normal conditions of use.
ln case of doubt, the tests are made at an ambient temperature of (20 ± 5)℃.
