OECD publishes new and updated test guidelines and other documents
Posted on 2023-07-28On July 4, OECD published two new test guidelines and 19 updated or corrected test guidelines. The complete list of newly available documents is accessible at https://www.oecd.org/env/ehs/testing/oecdguidelinesforthetestingofchemicals.htm.
One new Test Guideline, Test No. 444A, describes the IL-2 assay, an in vitro assay intended to be used as a part of a battery to determine immunotoxic potential of chemicals. The other new test guideline, Test No. 126, describes a method to measure hydrophobicity of nanomaterials. Among the updated and corrected test guidelines are tests describing non-animal approaches for assessing skin sensitization, eye irritation, endocrine activity, and phototoxicity.
In addition to the test guidelines, OECD also added two documents to its Series on Testing and Assessment: “Initial Recommendations on Evaluation of Data from the Developmental Neurotoxicity (DNT) In Vitro Testing Battery” and a “Workshop Report on How to Prepare the Test Guidelines for Emerging Technologies.”
