Read across approach

Term
Read across approach
Definition

means an approach to predict the hazard characteristics of a chemical (target chemical) and fill information gaps by using information from one or more other chemicals (source chemicals). There are 2 read-across techniques:

  • Analogue approach – a single chemical is used as the source chemical (this single chemical is then known as the ‘analogue chemical’) 
  • Category approach – a group of chemicals are used as the source chemicals.

Suitable read across information means that that read across approach is acceptable to fill an information gap for a hazard characteristic because all of the aspects outlined in Appendix 8.3 of the Industrial Chemicals Categorisation Guidelines have been considered, justified and documented.
