Thank Harry for the additional information about 1.0 in-lbs for the ASTM F-88 peel test. I have used that number for the last 7 years and never knew the lineage. (min pdg std for J&J and MDT)
Hi Paul, actually the units for F88 seal strength are
pounds per inch (lb/in.), not inch-lbs. - common error.
Tribal knowledge has it that the 1.0 lb/in was generated by the coating supplier as a spec that they could reasonably guarantee. Nothing more than that. The actual source of a manufacturer (MDM, not the supplier or other external entity) spec. is whatever will withstand subsequent processing, e.g. sterilization, distribution simulation and the like. The min spec. can be whatever you wish as long as you have reasoned, defensible rationale that will sustain scrutiny.
If you have a light product (e.g. band-aid), it can be .25 lb/in. For something heavy and bulky, you'll need something stronger. But you have to defend your choice. Show your work, bring receipts.
