The method described by this Test Guideline provides information that allows hazard assessment for short-term exposure to a test article by inhalation, and allows the substance to be classified according to the Globally Harmonized System of Classification and Labelling of Chemicals (GHS). The...

This method provides information on health hazard likely to arise from exposure to liquid or solid test substance by dermal application. This Test Guideline recommends sequential testing strategies, which include the performance of validated and accepted in vitro or ex vivo tests for...

The method permits estimation of an LD50 with a confidence interval and the results allow a substance to be classified for acute toxicity according to the Globally Harmonised System of classification and labelling of chemicals. It is easiest to apply to materials that produce death within couple...

A developmental neurotoxicity study will provide information on the effects of repeated exposure to a substance during in utero and early postnatal development. The test substance is administered daily, generally orally, to mated females (rats are preferred) from the time of implantation (GD 6)...

This Test Guideline describes an in vitro procedure that may be used for the hazard identification of irritant chemicals (substances and mixtures) in accordance with the UN Globally Harmonized System of Classification and Labelling (GHS) Category 2. It is based on reconstructed human epidermis...

This Test Guideline is for an in vitro membrane barrier test method that can be used to identify corrosive substances. The test method utilizes an artificial membrane designed to respond to corrosive substances in a manner similar to animal skin in situ. The in vitro membrane barrier test method...

The in vitro micronucleus test is a genotoxicity test for the detection of micronuclei in the cytoplasm of interphase cells. Micronuclei may originate from acentric chromosome fragments (i.e. lacking a centromere), or whole chromosomes that are unable to migrate to the poles during the anaphase...

The Local Lymph Node Assay: BrdU-ELISA (LLNA:BrdU-ELISA) is a non-radioactive modification to the LLNA method for identifying potential skin sensitizing test substances and measuring the proliferation of lymphocytes they induce in the auricular lymph nodes. The method described in mouse is based...

The Uterotrophic Bioassay is an in vivo short-term screening test. It is based on the increase in uterine weight or uterotrophic response. The Uterotrophic Bioassay relies for its sensitivity on an animal test system in which the hypothalamic-pituitary-ovarian axis is not functional. Two...

This Test Guideline for developmental toxicity testing is designed to provide general information concerning the effects of prenatal exposure on the pregnant test animal and on the developing organism. The test substance is normally administered to pregnant animals at least from implantation to...
