Quality control planned experimentation

This effect has not been found in the source measurements carried out by the same or different operators in the same or different laboratories, with the same make of apparatus. None of the levels of error of measurement ever relates to an experimental value of flashpoint. This is incredible since over the past few years techniques of statistical control of testing and experimental planning have been developed which are now compulsory for some activities under the ISO 9000 quality standard. 

In summary, while a study has to fulfil certain requirements, such as the presence of a study plan approved by dated signature of the Study Director before the start of the study, and while it has to undergo some control through inspections by the Quality Assurance, there may be instances where certain of these requirements would become nearly impossible to be fulfilled. Where a study is, however, of so short experimental duration, that it would be practically impossible to schedule the respective inspections, and where the administrative workload would become much higher than the workload for the actual conduct of the study itself, then, GLP would by right be considered a burden only. Therefore the requirements of GLP are adapted by the Principles to short-term studies in a way that allows for a certain alleviation of the workload for Study Directors, study personnel, and Quality Assurance.
