ISO withdrawn standards

How to deal with withdrawn ISO standards still shown on drawings?
What is your best recommendation? How your company is doing it?


Nevertheless, withdrawn standards can still be used within an industry, community or by a government, and this is often what happens when there are no replacement technical documents readily available. Withdrawn standards are therefore still available in the ISO catalogue (though are marked as withdrawn) and can be purchased from the ISO webstore.

"Withdrawn" doesn't necessarily mean null and void.

If it is on your drawings because the requirements worked well for you, have those requirements changed just because ISO has "withdrawn" it?

 
Kedu,

You call up standards to tell people how to interpret your drawing. I am not familiar with the ISO standards. Let's say I call up ASME[ ]Y14.5M[‑]1994, the dimensioning and tolerancing standard. This has been superseded, however, this is what I prepared my drawing to. Some of the symbols and specifications have changed meaning on the later standards, and a couple of things, like concentricity and symmetry have been deleted. I don't want to be accountable for my drawing to be correct as per the newer versions of the standard, especially if I was not aware of them at the time.

I am fine with learning new standards and preparing my new drawings according to them. I suppose I could do a revision and go through the drawing and update everything to the new standard, but this is a lot of work. I might introduce a mistake. The vendor's interpretation of the new drawing may require them to do new tooling. I would leave this thing be.

I agree with what have been already said: use withdrawn ISO standards since that is reflecting better the functional requirements during the drawing conception. What would be the value added to change to the most up-to-date ISO standards? Why?
But anyway, I know who knows the correct answer. [bigears]

Pmarc,
If you are around, could you, please provide an acceptable ISO solution? What do you think?

 
There should be a difference between superseded and withdrawn. I recall the Y14 group tried to write a specification for optical elements, which was eventually withdrawn as there was already some other industry specification. My guess "withdrawn" means, "can't get people to buy it."
