Hi, G. There is no such formula. If you are processing per a spec, that spec will often dictate the number of hours required. If you are not processing per a spec, or the spec does not dictate the number of hours, then you find satisfactory parts, test them, and use that number of hours in the future as a way of checking that your process has not deteriorated.
