Am I missing the point. What a lot of fuss over if the measuring equipment carries some form of marking which identifies it as belonging to the "customer".
I think you are a bit - but welcome to the Cove and discussions in any case.
The focus in this thread was supposed to be (as it should be) on answering the question posed by the person who posted it - the 'original poster'. That's what he asked about and what was important to him.
You raise a number of very good points about other important issues... but they weren't what he'd asked for help about.
But yes, the thread
did start to get rather muddled and 'off topic' - the waters were muddied by a reference to a completely different standard (TS16949) rather than the ISO 9001 which is this forum, and then a few distractions crept in from that. Ideally, the aim is to keep the discussion in any particular thread to the question raised, and indicated by the topic of the thread. The moderators do a great job in trying to aid this.
Once quite different questions are raised in a thread, it becomes confusing, sure makes searching difficult, and worst of all, may not answer the question raised by the poster.
If you have a question you're interested in, and can't find anything on that after searching (to see if it's already been discussed lots), why not start a new thread?
