For those clients who have a preferred manufacturer, the testing of a design would be the last
stage that PESL would be involved with. At this stage we would soak test all of our designs
and check that the operational extremes or compliancy to the appropriate regulations can be
met. At the end of this stage a full R & D report would be generated to allow efficient end
manufacture with a client's manufacturer of choice. PESL would expect to liaise with any
manufacturer so as to smooth over the transition from R & D to production.
