Hello Elamin O. M. Akoy,

standard is the water boiling test: http://www.pciaonline.org/files/WBT4.1.2_0_0.pdf ; http://cleancookstoves.org/technology-and-fuels/testing/protocols.html

Safety: http://www.pciaonline.org/files/Stove-Testing-Safety-Guidelines.pdf

If you think of using solid fuel, don't forget to measure particulate matter, protocols you can find at http://cleancookstoves.org/technology-and-fuels/testing/protocols.html

Actually it depend upon the fuel you used.

if you use simple solid fuel like wood of dry leaves, you can know the performance by calculation of carbon conversion efficiency..

More is the carbon conversion efficiency, better is the fuel to burn.

thank you all for the valuable information

what ever the fuel you use it must be active to consume short time and with less air contamination.
