I think we can assume that there is no such animal Geoff. We write new procedures for each new (different) device that comes in. The schedule is based on the manufacturer's service instructions that way we cover ourselves against litigation if something does go wrong. It can be a ball ache if for example one syringe driver is tested at 50ml/h over 6 minutes and another at 25 ml/h over 12 mins. Does it really matter if you calibrate the occlusion pressure at 3.5 KgF or 4.0KgF? To us as engineers it makes little difference but in the eyes of the court we could have some explaining to do!
