The Organisation for Economic Co-operation and Development maintains a set of internationally harmonised test guidelines that define standardised protocols for toxicity testing — for example OECD 407 (28-day repeated-dose toxicity), OECD 408 (90-day sub-chronic toxicity), OECD 423 (acute toxic class method), and OECD 452 (chronic toxicity). Data generated under OECD guidelines and GLP conditions are mutually recognised across OECD member and adherent countries, substantially reducing duplicative animal testing.
