Foreword

All technical content in this section is mandatory. GB 20041 "Conduit systems for cable management" is divided into two parts. --- Part 1. General requirements (GB/T 20041.1) --- Part 2. Particular requirements (GB 20041.21 ~ 20041.24) ● Part 21. Particular requirements for rigid conduit systems ● Part 22. Particular requirements for flexible conduit systems ● Part 23. Particular requirements for flexible conduit systems ● Part 24. Particular requirements for conduit systems buried underground This is Part 23 of GB 20041. This section should be GB/T 20041.1-2005 used in conjunction.

7 Marking and documentation

GB/T 20041.1-2005 after this chapter apply for the following modifications. increase. 7.1.101 conduit should be identified in accordance with the requirements of 7.1. Logo should at regular intervals along the full length of the catheter, as the most suitable interval 1m, not more than 3m. As in the case of technology can not be implemented, logos can be marked on the label attached to the end product or packaging. Compliance is checked by inspection. 7.1.102 The manufacturer shall provide documentation for the system or marked on the package, to illustrate the minimum diameter, minimum bend radius and in accordance with Chapter 6 classification. Compliance is checked by inspection. Size 8 instead. GB 20041.23-2009/IEC 61386-23.2002 8.1 Threads shall comply with GB/T 17194. Compliance is checked by measuring gauge GB/T 17194 stipulated to check. The minimum inner diameter of 8.2 catheter system shall be declared by the manufacturer. Compliance is checked by measurement.

9 Structure

GB/T 20041.1-2005 this chapter apply. 10 Mechanical properties GB/T 20041.1-2005 after this chapter apply for the following modifications. 10.1 mechanical strength 10.1.1 Addition. Note. very light, flexible catheter should not be considered to have sufficient mechanical protection, and should not be used in building construction. 10.4 Bending test GB/T 20041.1-2005 this section does not apply. 10.5 bending test 10.5.101 from conduit terminating conduit fittings with the composition of the components according to the manufacturer's instructions assembled, you should use 101 as shown in Fig. Means for bending test. 10.5.102 test should be used as a conduit 6 samples having a suitable length, three specimens should be minimum transport, use and safety provisions in Table 1 Means test temperature ± 2 ℃ under. Further three samples shall be carried out in Table 2 below the specified maximum transport, use and installation temperature ± 2 ℃ in test. Manufacturers can declare a flexible catheter adapted to a predetermined temperature in accordance with Table 1 transport and installation, but only for a minimum temperature of ambient temperature Bending degree, this time, the test shall be at (20 ± 2) ℃ were, classification code and the first three digits should be X. The manufacturer shall, in its written materials The transport and installation explicitly stated minimum temperature according to Table 1, the lowest temperature of the ambient temperature and the maximum temperature in accordance with the installation and use Table 2. 10.5.103 terminating conduit fittings should be used as shown in Fig. 101 is fixed to the specimen swing body, when the catheter is moved to the middle position, the catheter Axis is vertical, and passing through the pivot shaft. Equipped with a device should be placed after the sample under specified conditions 2h, or until the sample temperature reaches declaration Degree, whichever is longer. 10.5.104 pendulum should axis vertical axis, swing, swing the total angle of (180 ± 5) °, the average separated by a vertical axis. Components should be Per minute (40 ± 5) times the rate of 5000 fold. From the vertical position start, once a week sinusoidal movement bent. 10.5.105 After the test, the sample should be no signs of split, nor come now without additional amplification normal or corrected vision visible crack. 10.6-destructive testing GB/T 20041.1-2005 this section does not apply. 10.7 Tensile strength GB/T 20041.1-2005 purpose of this regulation for the following modifications apply. 10.7.3 Replacement.
