JaCVAM Statement on theIn Vitro Skin Corrosion: Transcutaneous Electrical Resistance Test Method(TER)
At a meeting held on 25 July 2017 at the National Institute of Health Sciences (NIHS) inTokyo, Japan, the Japanese Center for the Validation of Alternative Methods (JaCVAM)
Regulatory Acceptance Board unanimously endorsed the following statement: 
Proposal: We consider the Transcutaneous Electrical Resistance Test Method (TER) to besuitable for predicting the skin corrosion potential of a test chemical in a
regulatory context. We are concerned, however, that the use of isolated rat skin inthis test method for the safety evaluation of cosmetic ingredients and products
could be problematic due to the prohibition on animal testing for cosmetics thatare sold in the EU.
This statement was prepared following a review of the Organisation for Economic
Co-operation and Development (OECD) Test Guideline (TG) 430 In Vitro Skin Corrosion:
TER Test Method together with other materials prepared by the Skin Corrosion Testing
JaCVAM Editorial Committee to acknowledge that the results of a review and study by theJaCVAM Regulatory Acceptance Board have confirmed the usefulness of this assay.
Based on the above, we propose the TER test method as a useful means for assessing skincorrosion potential during safety assessments by regulatory agencies.
