Incoming Material Inspection Plan - Drawing CTQ (Critical to Quality) features linked

I would like to start labeling CTQs or Critical to Quality features on our drawings as an integral part of our incoming inspection plans for each part. Does a standard symbol or format exist for doing this?

I know of no 'industry standard' or other standard. If you look at QS9000 Appendix C you can see in automotive there are a number of designators used by each of the big three. I suggest you choose anything other than one of these to avoid confusion. You could get creative and take a tiny picture of a scowling face and use it for your 'symbol'! Don't forget to document (define) it whatever you decide to use.

It's not clear what you're looking for--do you want some sort of training materials? What are you trying to do?

From what you described, it would appear that you do not have an established internal standard or practice.

If you do contract manufacturing for the big boys, they will normally specify all these. If you don't, check around with people in the industry - they can point you to suppliers to these people and you can get your answers from them.

If not, just purchase some products of your competitors. Look at how they do their packaging, what material they used and make a decision for your organization.

For fluorescent tubes, I noticed that most people copied the packaging of the market leaders - basically single walled corrugated carton material.
