Can ISO/IEC 17025 serve as a tool to prevent scientific fraud in chemical research laboratories?
The Canadian Journal of Chemical Engineering, EarlyView.Abstract Scientific fraud has been documented across multiple disciplines, and chemistry is no exception. Recent studies indicate that contamination of materials, methodological errors, and unreliable data, results, or analyses account for over 25% of retracted publications.
