This study presents an overview of lamps and stoves samples testing conducted by three institutes: Chengdu Energy Environment International Cooperation (CEEIC), Chengdu in line with Biogas Appliances Quality Inspection Center of the Ministry of Agriculture, People's Republic of China; Department of Renewable Energy Sources (DRES), College of Technology and Engineering, Maharana Pratap University of Agriculture and Technology, Udaipur, India; and Kiwa Gastec
Certification (GASTEC). Stoves samples were obtained from Bangladesh, Cambodia, Ethiopia, India, Lesotho, Nepal, Rwanda and Vietnam and lamps samples from Cambodia, Ethiopia, India and Nepal.

Study findings for both lamps and stoves are provided for each country individually. The general findings of the report indicated that no stove qualified for quality certification under both Chinese and Indian specifications. Further, the stove samples from Bangladesh and Cambodia have only met the minimal thermal efficiency standards. As for the lamps samples, the one from Cambodia performed better at CEEIC and DRES, while the lamp from India showed better luminous efficiency at GASTEC.

The study also discusses the main problems encountered with the stoves and the lamps, where some of the stoves problems include low heat flow (Bangladesh) and no air-intake (Cambodia & Bangladesh). Lamp problems included improper design (Ethiopia), small mud head (Nepal), etc. Based on the study findings specific recommendations were designed and presented in the report. For stoves, the most critical issue was the need for standardization of parts. Lamps recommendations included the necessary increase of burning area, increase in heat flow to improve thermal efficiency, etc.
