CSE 5.01 reference on drawing

[TPMB4]

We've received a drawing from our customer in the automotive sector and there is a symbol of a key (car key shape) with a box containing CSE 5.01. It is next to the dimension box that has T=10mm if that's relevant.

It's kind of embarrassing not to understand what is meant on the drawing but nobody at work has ever seen CSE5.01 reference before.

Does anyone have a clue what it means?

It could be a specialized standard or spec. Best thing to do is ask your customer. It would be better to ask a question that seems stupid now than to make an assumption that has the potential to blow up big in the future. Ideally, this question would be asked during the feasibility analysis process.

Hope this helps!

I'm with @Emmyd. ALWAYS ask the customer if you're not sure. You can't depend on anyone here giving you the correct information.
