Physico-chemical properties (incl. nanomaterials)	- OHTs 1 to 23-5 & 101 to 113
Environmental fate and behaviour	- OHTs 24 to 40 & 401
Effects on biotic systems	- OHTs 41 to 57
Health effects	- OHTs 58 to 84 & 86
Pesticide residue chemistry	- OHTs 85-1 to 85-10
Analytical methods	- OHT 87
Efficacy	- OHTs 88 & 89
Emissions from treated articles	- OHT 90
Intermediate effects	- OHT 201
Use and exposure information	- OHTs 301 to 306
Generic elements for all OHTS	- Literature reference - Test material information                       - Reference substance - Chemical inventory

Each Template is accessible online in readable format (.doc file), with associated html schema (.xsd file), and with predefined tables and executive summaries (.html files) as available. The links to corresponding OECD Test Guidelines are given where applicable.

All OHTs can also be downloaded at once from a single zip file which collates the 130 OECD Harmonised Templates and their related materials.
