Intent of Applicable Documents in IPC-2221

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Hi all,
IPC-2221B has a bunch of "applicable documents" (about 65 listed). The text heading this list says "The following documents form a part of this document to the extent specified herein. If a conflict of requirements exist between IPC-2221 and those listed below, IPC-2221 takes precedence."

So are those meant to be compliance docs (the cited document contains requirements included in the citing document by reference)?

Or are they considered to be reference docs (the cited document provides data or information useful in enhancing the understanding of the citing document"?

The heading text (on top of the list of other standards)... doesn't say that they are also required, and if it did mean that they requirements too, it doesn't say what specific rev of that standard.

Anyway, if a person was asked to certify that a design complied with IPC-2221B... are they actually meaning "does it also comply 100% with these 65 listed standards?"

PS - in the IPC checklist, there's some text saying “applicable
documents are referenced in the standard but the requirements are not invoked
unless specifically stated” (that text does not appear in IPC-2221B, but I would think that the intent would be the same... and that these are actually meant to be Reference docs, not Compliance docs)

Regards,
Chris

	I'm thinking the phrase "to the extent specified herein" means that it's only if IPC-2221B calls out a specific requirement from one of those standards... that requirement would have to be met. But just listing all 65 standards, doesn't mean that all 65 are "compliance standards" and everying in them has to be met. Regards, Chris
