Singapore and India are indeed former British colonies and are both commonwealth countries now as well as Australia and New Zealand. Indeed the former British Empire was so big and thus PIClist is using English, not any other language. ;-) Still I see the wiki page (by no means should be considered as correct) of ISO_31-0 at the following URL. http://en.wikipedia.org/wiki/ISO_31-0 the wavelength is λ = 6.982 × 10−7 m It is using dot and not a comma. Therefore I guess in the technical field people are still using dot instead of comma. Maybe ISO-31's next revision will use dot when China, India, USA and Japan pay more attention to the standards. ;-) The standard we deal with are mostly EN/ISO/IEC standards with EN50178/EN60947 and IEC61000 being the most frequently referenced, but lately I also need to reads UL508 and UL840 as well. And China's CCC mark become the latest standard we need to apply for AC powered device even though I still have no much ideas on how to apply for the CCC mark. The major problem is that different standard body (or different standard expert) interpretes the standard differently. I think my company employs quite some standard expert to deal with certification and it tends to be quite expensive.
