Safety characteristics for a substance from different sources may differ significantly. Round robin tests have shown that in nearly all cases this is not due to negligence or carelessness by the laboratory staff. Rather, the fluctuations are due to the complex nature of the properties described by the safety characteristics and to unprecise testing standards. The authors recommend initiating or intensifying initiatives to facilitate quality control in safety testing laboratories, like routine round robin test for many more methods and provision of suitable reference materials for tests, where such materials could help improve data quality.
