The OECD Harmonised Templates are standard data formats for reporting studies done on chemicals to determine their properties or effects on human health and the environment. They are aimed at developers of database systems, as they prescribe the formats by which information can be entered into and maintained in database. By using these templates, governments and industry will easily be able to electronically exchange test study summary information. The templates can be used for reporting summary results for testing on any type of a chemical (e.g., pesticides, biocides, industrial chemicals).

What's New

1 new and 3 revised Templates now available online (16 February 2015)

One new and three revised OECD Harmonised Templates for Reporting Chemical Test Summaries (OHTs), developed and approved during 2014, are now published online. The new OHT 75-3 on Endocrine disrupter mammalian screening – in vivo (level 3) was designed to cover the reporting of uterotrophic and Hershberger bioassays. The revised templates from the Series on ‘Health Effects’ (OHT 67: Repeated dose toxicity: oral; OHT 72: Carcinogenicity; and OHT 73: Toxicity to reproduction) were updated to align them with some revised/new OECD Test Guidelines. The four OHTs are available with all other files at “TEMPLATES”, while their additions and changes are listed in the “UPDATE Overview” at the date of 24 December 2014
