Clause 7 of IEC 61386-1:2008 and of IEC 61386-1:2008/AMD1:2017 are applicable, except as follows:
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, themark shall be on a label attached to the product at each end, or on the packaging.
Compliance is checked by inspection.
7.1.102The manufacturer shall document or include in the packaging, the minimum insidediameter, the minimum bend radius and the classification in accordance with
Clause 6 for the
conduit system.
Compliance is checked by inspection of the documentation.
8Dimensions
Replacement:
8.1 Threads shall comply with lEC 60423.
Compliance is checked by means of the gauges specified in lEC 60423.
8.2The minimum inside diameter of the conduit system shall be as declared by themanufacturer.
Compliance is checked by measurement.
9construction
Clause 9 of lEC 61386-1:2008 is applicable.
10 Mechanical properties
Clause 10 of IEC 61386-1:2008 and of lEC 61386-1:2008/AMD1:2017are applicable，exceptas follows:
10.2Compression test
Subclause 10.2 is applicable with the following addition:
10.2.4Add the following note at the end of Subclause 10.2.4:
NOTE In order to achieve a uniformly increasing compression force， the force indicated in Table 4 is divided bytime;this value is the required rate per second to fulfil the requirement,
Example: For a test force of 750 N an increase of the test force of 25 Ns is required (750 divided by 30 equals 25).Informative Annex AA gives detailed calculations including tolerances for time and force,
10.4Bending test
Subclause 10.4 of lEC 61386-1:2008 is not applicable.
10.5 Flexing test
Addition:
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 101.
