In my view, I have never seen an encyclopedia where humorists or jokesters are welcomed to display their savvy in pointing out the satirical side of knowledge. Wikipedia users seek informed knowledge — not informed humor, nor informed jokes. <!-- Template:Unsigned --><small class="autosigned">— Preceding [[Wikipedia:Signatures|unsigned]] comment added by [[User:OIBtheOne|OIBtheOne]] ([[User talk:OIBtheOne#top|talk]] • [[Special:Contributions/OIBtheOne|contribs]]) 17:55, 15 November 2016 (UTC)</small> <!--Autosigned by SineBot-->
==Third digit==
Can someone please provide a reference for the section on the third digit? This is clearly not in the IEC or DIN standard. [[User:Markus Kuhn|Markus Kuhn]] 21:19, 13 August 2005 (UTC)
Moved the third-digit section over here, until someone can back it with a reference. [[User:Markus Kuhn|Markus Kuhn]] 10:12, 28 August 2005 (UTC
:Not defined in IEC 60529, but (presumably?) covered in some national variants of the standard, is an optional third digit that can be added to indicate how well the enclosure is protected against mechanical impact damage. The table below lists both the impact energy in [[joules]], as well as the mass of a test opject that will provide this impact energy if dropped from the given height above the impact surface.
