Today simulation modeling is the preferred approach for figuring out the habit of advanced networks. With the supply of particularly reasonably cheap advertisement programs for doing simulations, community designers and community functionality analysts can now achieve perception into the collective habit of community units corresponding to servers, routers, and switches with a excessive measure of accuracy.

25 mm2 flexible cord as given in Table 27 of BS 6500:2000. Non-rewirable accessories are tested as delivered. The free end of the flexible cord which is approximately 2 250 mm long is fixed to a wall at a height 0 of 400 –10 mm above the floor, as shown in Figure 22. The specimen is held so that the cable is approximately horizontal and then it is allowed to fall on to a concrete floor eight times, the flexible cord being rotated through approximately 45° at its fixing each time. 4b) and Clause 15 and Clause 16.
X Example 3 Example 3 Condition: Rule: Path under consideration includes a V-shaped groove with a width greater than “X” mm. Clearance is the “line of sight” distance. Creepage path follows the contour of the groove but “short circuits” the bottom of the groove by an “X” mm link. --`,,`-`-`,,`,,`,`,,`--- 32 Copyright British Standards Institution Provided by IHS under license with BSI No reproduction or networking permitted without license from IHS © BSI 9 October 2003 Not for Resale BS 1363-2:1995 --`,,`-`-`,,`,,`,`,,`--- Example 4 Example 4 Condition: Rule: Path under consideration includes a rib.
After 5 000 flexings, socket-outlets are turned through 90° ± 5° about the cord entry centreline. NOTE A flexing is one movement through 90°, either backwards or forwards. During the test there shall be no interruption of the current passing through the conductors and no short circuit between them. After the test the sample shall show no damage except that breakage of no more that 10 % of the total number of conductor strands in any core is ignored provided they have not pierced the insulation.
