Method Validation

Collaborative and Cooperative Testing

This is an activity or component of method validation that is performed by organizations that develop standard methods of chemical analysis such as ASTM and AOAC. It is also an activity that is performed by large corporations with multiple testing locations. The term reproducibility is used to describe interlaboratory precision and is expressed as standard deviation. Different organizations use different processes, some more convenient than others. For this reason, refer to the following references:
