The Household Environment and Health (HEH) Project, funded by the Shell Foundation, has developed standard protocols for indoor air pollution (IAP) measurements and stove performance tests (SPTs). These SPTs are updated and revised versions of tests first developed in pioneering work by Volunteers in Technical Assistance (VITA, 1985, Testing the Efficiency of Wood-burning Cookstoves: Provisional International Standards).
Water Boiling Test (WBT)
This type of SPT is a lab-based test designed to explore the most basic aspects of stove performance in a controlled environment. As it is a short test and the results are not highly variable, relatively few tests can give useful and quick feedback in laboratory and simulated settings to test, for example, the effect of changes in stove design, fuel quality, and other physical variables. It is also useful in field tests to determine whether stoves have been built to faithfully match their design criteria. Modified WBT protocols were used as part of the performance criteria for both the Indian and Chinese national improved stove programs.
The WBT, on the other hand, is not an accurate way to determine actual fuel use under field conditions or changes in fuel use, for example from introduction of an improved stoves. For this, the Kitchen Performance Test (KPT) (see below) is the best available test.
The latest WBT protocol (v3.0 January 2007) is below. Also included are links to technical appendices explaining how the calculations are carried out.
