Contract Research Reports
Manually operated sprayers - when used professionally - are expected to have a working life of several hundred hours. During this time, the machines may undergo changes that can affect their safety characteristics. Hence the new proposed International Standard now makes some provision for preconditioning the machines before they are tested; an aspect of research that has not previously been systematically measured. However, the duration of the preconditioning period remains debatable. Should it simulate a time scale that is appropriate to professional use for a year [250 hours] or should it be just for a few hours [25 hours] to identify manufacturing limitations?
Some of these research reports are very large. For information about expected download times please see our FAQs pages.
