[Stoves] Test procedures

[Frank Shields]

Dear Crispin,

One such group I was involved in was the IBI Carbon Sequestering protocol. That was very successful IMO. So it can work.

There are books of test methods to pick from. They are assembled to make a protocol. Then the results have a conclusion assigned to them. 

Its the ‘conclusion assigned to them’ where it all starts. The test methods often need to be modified and the assembling of them needs to be such that it validates the ‘conclusion assigned to them’. Many test procedures fall short along the way and their conclusion claims are not substantiated. Experts not having lab experience are unlikely to willingly modify test methods. And the protocol often not conducted to validate the conclusion. I see this a lot. 

Its easy to see why stove tests done in the lab using processed fuels for a conclusion that this stove is better than this stove is not a valid test protocol when its wild fuel that is used at the site.

Its easy to see why it would be useful to have a lab test where many stoves can be tested to determine the best stove for a specific site. I think this can be done. But I have not a hint of anyone working towards this approach. 


Regards

Frank

This is a project of S4G (the South-South Sustainable Stoves Group), a collaboration by experts from more than 10 developing countries each of which contributes expertise.

At present the whole test protocol is less than 20 pages long and provides an easy to follow set of procedures with valid, meaningful metrics. I hope it will be generally available this calendar year.

And when that is all done, it is still published for public comment for 60 days to get reviews by external parties. The IWA 2012:11 calls for all stove test methods to be expertly reviewed (and ‘pass’) by external parties. So far as I hear, only one has been which is the HPT from the SeTAR Centre (multiple times – four that I know of).

Grouping experts, each with their own idea, together to come up with the best does not work.  A better way is to let each person/group  develop their own idea. Then a presentation of the ideas presented for one to be picked.
