5.7 Where required for heat ageing, a full draft circulating-air oven as specified in lEG 60216-4-1:2006 shall be used. A portion of the air shall be allowed to re-circulate and a substantial amount of air shall be admitted continuously to maintain the normal air content surrounding the samples. The oven shall be adjusted to achieve more than 5 complete fresh-air changes per hour.
5.7DV Dl Modify 5.7 by adding the following text:
In Mexico, an oven as specified in NMX-J-417-ANCE-2005 is considered equivalent.
5.8 A fixing device that is integral to a cable tie shall comply with the requirements for both the fixing device and the cable tie. The integral assembly shall be classified according to 6.2.2 or 6.2.3 and subjected to the conditionings for the cable tie prior to conducting the mechanical strength test for the fixing device according to 9.7.
A fixing device, the performance of which is dependent on the mounting hole size, the thickness of the material sheet to which it is to be mounted, or the mounting orientation declared by the manufacturer according to 7.3 f), shall comply with all applicable tests when the device is assembled to the minimum and maximum thickness of each mounting surface, in the largest hole size, and in each intended mounting orientation declared by the manufacturer.
When it can be determined that a particular mounting orientation represents the most onerous condition, the results of the tests in that orientation may represent all mounting orientations.
5.8DV Dl Modify 5.8 by adding the following paragraph:
A surface-mounted fixing device, the performance of which is dependent on the mounting surface or the mounting orientation, shall comply with all applicable tests when the device is assembled on the surfaces for which it is intended, and in each intended mounting orientation declared by the manufacturer. If the manufacturer does not make a declaration of mounting orientation or when it can be determined that a particular mounting orientation represents the most onerous condition, the results of tests in that orientation may represent all mounting orientations.
5.9 Unless otherwise specified, when conducting the tests on cable ties in Clause 9, the samples shall
be installed according to the manufacturer’s instructions on a steel or aluminium mandrel which has a
diameter A according to Table 2:
If the minimum declared diameter of the cable tie is greater than the diameter of the test mandrel specified in Table 2, then a test mandrel that has the minimum diameter as declared by the manufacturer shall be used.
The width B of the mandrel shall be at least 5 mm greater than the maximum width of the cable tie as shown in Figure 2.CSA C22.2-No.62275 pdf download.
