Testing is not required

- Testing, unlike collection and analysis of data, is not required for the HazCom standard.
The standard does not require the testing of chemicals — only the collection and analysis of currently available data. Nevertheless, if no data is available or it is questionable, testing should be considered when hazardous properties are suspected.
Tests conducted according to internationally recognized scientific principles can be used for purposes of hazard classification. In the case of health hazards, for example, this includes the results of valid in vitro tests, relevant animal data, and human experience, such as epidemiological and clinical studies, and well-documented case reports and observations.
If no hazards are found, the manufacturer, importer, or employer is not required to take further action pertaining to the evaluated chemical.
