No Sampling of Aging Instruments in the Field


To suggest that ATC/CFS scientists cannot provide any scientific opinion of the reliability of aging instruments out in the field without conducting an empirical study of instruments sampled from the field.

To suggest that ATC/CFS scientists have no idea whether or not instruments in the field are performing in accordance with manufacturer's specifications.

To identify the lack of any system of "verification" in Canada that instruments in the field are performing in a manner similar to the instruments originally evaluated and given type approval.

To contrast the evaluated accuracy and precision of instruments evaluated by the ATC with actual accuracy and precision of instruments in the field.

To suggest that unlike gas pumps and retail meat scales, in Canada, we have no system in place to control "verification" that an individual instrument conforms to "type approval" of an approved instrument.

To suggest that in Canada we have no system of mandatory periodic verification of individual instruments in the field to ensure that they conform to type approval.
