Best Practice Drawing Date
Best Practice Drawing Date
(OP)
I have worked at locations that have done this both ways and I was wondering what was considered the best practice.
For a drawing, the date drawn:
Should this date be the last data modified, so if you run through tree Work In Progress revisions, should the date be representative of the last time it was modified? In this Case WIP 1.
Or
Should the date show the first date that the revision process was begun for that rev of the drawing? In this case the date should show the date WIP 1 was begun.
Also are there ISO or other internationally accepted standards for this or similar subjects?
Thanks for your input.

Revision dates are recorded on the change documentation and often in the revision block. I have usually seen it recorded as the date the revision was approved, not started.

Then the other version was where the drawing creator and date was maintained in the title black with the current author and date in the rev block.
I'm maintaining standards at my company and we currently use the first option, but I'd like feedback oh what seems to work best.

Revision block, new date for each revision.
If the drawing is redrawn or replaced, the original names and dates are retyped.
This is an older document that specifies it.Link

Any other date before this is an arbitrary point in time as far as the person using the drawing is concerned.
If you date something when you start it, then a revision of a drafting standard is released, then you release your drawing, you are declaring it to be in conformance with the old revision of the drafting standard. If you date it when released, you are declaring confromance with the new revision of the standard unless you state otherwise.
I dont know if its referenced in ISO standards anywhere but ISO 8601 tells you the format to write your date in, which everyone calls me pedantic for trying to enforce.

Titleblock data is always the signatures and dates of the original document release for that document type. In our case, we use alpha revisions for pre-production releases and nukmeric for production releases. Revs A and 0 both have clean titleblock and no revision data. Some parts may have 3-5 pre-production revisions before the part is converted to rev 0 and released for production.

RE: Best Practice Drawing Date
Original date of the drawing should be maintained through out the revisions.
For each revision the date maintained varies with the system, with some doing the date the revision was begun and others doing the date it was first checked, but so far none that have the drawn date and the release date for that revision as the same.
There does not appear to be a standard ISO or otherwise maintained as an over arching standard of practice, however there are standards in place that are used by NASA or other government agencies which have been adopted by multiple companies.
Is that about right?

This is referencing 'ISO 7200:2004 - Technical product documentation – Data fields in title blocks and document headers', of which I don't have a copy to hand.

I think the most important thing is that you have a documented standard way to deal with it and you stick to your procedure.
