eltron,
Thanks for the link. It seems to be a useful website, but I've printed out what I need at the moment.
dalcazar/dipak, I'll keep a lookout for yr suggestions.
Ashereng, you're right. Different companies have slightly different way of depicting the more uncommon symbols. However, what I am looking for is some form of global authoritative voice that decrees the standard symbols to be used by one-and-all. And then compare this with what we have at my company.
Or at least, something close to a global standard.
