IEC 60998-1:2002 pdf download.Connecting devices for low-voltage circuitsfor household and similar purposes – Part 1: General requirements.
3.7
ancillary part
part of a connecting device providing electrical and mechanical protection and/or mounting, for example, a base, an enclosure, a mounting rail, etc. (see Annex A)
3.8
rated connecting capacity
cross-sectional area of the largest rigid conductor(s) to be connected as stated by the manufacturer of the connecting device. In the case of a connecting device for flexible conductors only, the rated connecting capacity is the cross-sectional area of the largest flexible conductor to be connected
3.9
rated insulation voltage
voltage of a component, device or piece of equipment to which dielectric voltage tests and creepage distances are referred
3.10
rated current
current assigned to the device by the manufacturer
clearance
shortest distance in air between two conductive parts
3.12
creepage distance
shortest distance along the surface of an insulating material between two conductive parts
3.13
ambient temperature
temperature of the air surrounding the connecting device together with its enclosure, if any
3.14
temperature rise
difference between the temperature of the part under test, together with its enclosure, if any, measured under load according to the test specification and the ambient temperature
3.15
multiway terminal device
connecting device that consists of several terminals, insulated from each other in a common housing of insulating material, which are capable of being subdivided by the user to make connecting devices consisting of one or more terminals
3.16
unprepared conductor
conductor which has been cut and the insulation of which has been removed over a certain length for insertion into a terminal
NOTE A conductor, the shape of which is arranged for introduction into a terminal, or of which the strands are twisted to consolidate the end, is considered to be an unprepared conductor.
4 General
Connecting devices shall be so designed and constructed that in normal use their performance is reliable and without danger to the user or surroundings.
Compliance is checked by carrying out all tests specified.
5 General notes on tests
5.1 Tests according to this standard are type tests.
5.2 Unless otherwise specified, the samples are tested as delivered and installed as in normal use, at an ambient temperature of 20 °C ± 5 °C.
5.3 The tests are carried out in the order of the clauses.
5.4 Unless otherwise stated, three samples are submitted to all the tests and the requirements are satisfied if all the tests are met. If only one of the samples does not satisfy a test due to an assembly or manufacturing fault, that test and any preceding ones which may have influenced the results of the test shall be repeated and also the tests which follow shall be made in the required sequence on another full set of samples, all of which shall comply with the requirements.
NOTE The applicant may submit, together with the number of samples specified in 5.4, the additional set of samples which may be wanted, should one sample fail. The testing station will then, without further request, test additional samples and will reject only if a further failure occurs. If the additional set of samples is not submitted at the same time, the failure of one sample will entail rejection.
6 Main characteristics
6.1 The preferred values of the rated insulation voltage of the connecting device are 125 V,
250 V, 300 V, 400 V, 500 V, 600 V, 690 V, 800 V, 1 000 V a.c. and d.c., and 1 500 V d.c
6.2 The standard rated connecting capacities are 0,2 mm2, 0,34 mm2, 0,5 mm2, 0,75 mm2,
1 mm2, 1,5 mm2, 2,5 mm2, 4 mm2, 6 mm2, 10 mm2, 16 mm2, 25 mm2 and 35 mm2.
NOTE I For the time being, designation by wire gauges may be used in some countries (for example AWG in the United States and canada), instead of the cross-sectional areas expressed in mm2 (see Annex B).
NOTE 2 In the United Kingdom, 1,25 mm2 is a standard rated connecting capacity.
6.3 Ambient temperatures above 40 °C require T marking.
The preferred values are 55°C, 85°C, 110 °C, 140°C and 200 °C. If other values are used, they shall be multiples of 5 °C.
