1 Scope
This clause of part 1 is applicable, except as follows:
Addition:
This part of IEC 61 386 specifies the requirements for flexible conduit systems.
2 Normative references
This clause of part 1 is applicable.
3 Definitions
This clause of part 1 is applicable.
4 General requirements
This clause of part 1 is applicable.
5 General conditions for tests
This clause of part 1 is applicable.
6 Classification
This clause of part 1 is applicable, except as follows:
Subclauses 6.1 .3 1, 6.1 .3 2 and 6.1.3 3 are not applicable.
NOTE Flexible conduit systems according to 6.1 .1 1 , 6.1 .1 2, 6.1 .2 1 , 6.1 .2 2 and classification 1 X from 6.2.1 ,table 1 are not allowed in France.
7 Marking and documentation
This clause of part 1 is applicable, except as follows:
Addition:
7.1 .101 The conduit shall be marked in accordance with 7.1 along its entire length at regular intervals of preferably 1 m but not longer than 3 m. Where this is technically impractical, the mark shall be on a label attached to the product at each end, or on the packaging.
Compliance is checked by inspection.
7.1 .102 The manufacturer shall document or add to the packaging for the system the minimum inside diameter, the minimum bend radius and the classification in accordance with clause 6.
Compliance is checked by inspection.
8 Dimensions
Replacement:
8.1 Threads shall comply with IEC 60423.
Compliance is checked by means of the gauges specified in IEC 60423.
8.2 The minimum inside diameter of the conduit system shall be as declared by the manufacturer.
Compliance is checked by measurement.
9 Construction
This clause of part 1 is applicable.
10 Mechanical properties
This clause of part 1 is applicable, except as follows:
10.1 Mechanical strength
10.1.1 Addition:
NOTE Very light flexible conduits should not be considered as providing adequate mechanical protection and should not be used within the construction of buildings.
10.4 Bending test
This subclause of part 1 is not applicable.
10.5 Flexing test
10.5.101 An assembly consisting of a conduit with a terminating conduit fitting, assembled in accordance with the manufacturer’s instructions, shall be subjected to a flexing test by means of the apparatus shown in figure 1 01 .
10.5.1 02 The test shall be made on six samples of conduit of an appropriate length. Three of the samples shall be tested at the minimum declared transport, application and installation temperature as given in table 1 with a tolerance of ±2 °C. The other three samples shall be tested at the maximum declared application and installation temperature as given in table 2 with a tolerance of ±2 °C.
A manufacturer may declare that a flexible conduit is suitable for transport and installation according to table 1 but may only be suitable for flexing at ambient temperature as a minimum. In this case the test shall be carried out at (20 ± 2) °C and the 3rd digit of the classification code shall be X. The manufacturer shall clearly declare in his literature both the minimum transport and installation temperature in accordance with table 1 , the minimum application temperature which is ambient and the maximum installation and application temperature in accordance with table 2.
