IWA 11:2012

Guidelines for evaluating cookstove performance

IWA 11:2012 provides a framework for rating cookstoves against tiers of performance for a series of performance indicators, including

  • fuel use (efficiency),
  • emissions (carbon monoxide and particulate matter 2,5),
  • indoor emissions (carbon monoxide and particulate matter 2,5), and
  • safety.

IWA 11:2012 does not select a single laboratory protocol to determine cookstove performance. Instead, it enables stove testers to use laboratory protocols most appropriate for the stove and performance indicator being tested. Tiers of performance for each protocol chart all stove test results on the same page, in order to ensure equivalent results, regardless of protocol used.
