NEC ECC: Collateral Warranty for Framework Agreement

I have a question regarding collateral warranty requirement under NEC3. If there are numerous package order instructions issued under the framework agreement should collateral warranty be requested for each POI or if there is a collateral warranty for the framework agreement then it would apply to all the instructions issued under it?

I would imagine that the sensible thing to do would be to issue one collateral warranty that covers all of the individual orders rather than lots of individual warranties for separate orders. You would need to make sure that the wording of the warranty was appropriate.
