If that scenario is not the case, then the whole underlying concept of the "basic" safety requirements in international standards being "common" could be very severely undermined?

Unfortunately, one size does not fit all. We don't have enough distinct English words. German is better, but we really need a fully agglutinative language to express all the subtle shades of meaning.

It's very difficult to get people who are able (and funded) to do terminology work, and the present chaos would take an infinite team of monkeys for ever to sort out, especially as terms are being defined, or re-defined, all the time. -- OOO - Own Opinions Only.
