A to D
The 4 digit numbers listed (e.g. 1117) agree with the numbering code of the ISO Standard 1122/1-1983 (e.g. 1.1.1.7).
I would appreciate any help with this page, if you can translate the English term to your native language please submit it. Thanks to WH for filling in some of the German and TC for some missing French, is there any good Italian Engineers that could do the same?
