(Yes, I am quite out of touch with the latest in "Stove testing"

font-size: 10.5pt;" class="">This review
intended to collect and collate the
information related to cookstove
testing methodologies applied in lab
and field conditions and their
output in the form of energy and
emission parameters. The important
information related to progression
of cookstove testing techniques was
segregated in order to understand
the relationships in different
indicators of cookstove performance
and to understand the sources of
uncertainty in emission data. The
major research issue that has been
dwelt upon in the recent literature
is the establishment of relationship
between lab and field results of
cookstove performance. It is
observed that controlled cooking
test and kitchen performance test
are the two field based tests which
provide a better picture of a
particular cookstove performance as
it involves the user perspective.
Misrepresentation of actual
cookstove performance based on
laboratory based testing puts the
present standard protocols in
question. Solutions have been put
forward by some research studies;
however a validation is needed
through multiple scientific
investigations conducted at various
temporal and spatial scales. It has
been observed that cookstove testing
methodologies are still in their
nascent stage compared to the
research that has already been
conducted for other sources where
biomass combustion emissions have
studied thoroughly. Still the shift
in focus of upcoming research
studies towards field based
integrated cookstove testing
methodologies has the potential to
drive future cookstove research in
the new direction.</span></div>
