8. AEPC’s Initiative on Stove Quality Assurance & Testing on ICS Dissemination
The document outlines the efforts of the Alternative Energy Promotion Centre (AEPC) in Nepal to improve the quality assurance and dissemination of improved cooking stoves (ICS) from the 1950s to 2017. It discusses historical milestones, technical quality assurance methods, and selection processes for new stove models, emphasizing the importance of field testing and user acceptance. Additionally, the document highlights various studies assessing the effectiveness of ICS in reducing indoor air pollution and enhancing health outcomes.

- 3. AEPC’s National BiomassProgramme and effort towards standardisation of improved stoves AEPC believes improvement against traditional cooking practices are must… Adoption rate and efficiency of installed stoves at field level were always a matter of concern for the ICS programme… • How do we assure the technical quality of stoves installed in the field? • How do we selected new models for dissemination? • Where and how did we test stoves? • What are the contributions towards standardization in quality stove testing? • What are other initiatives?
- 4. Technical quality assuranceof stoves • Mud Stoves (not subsidized) – Inbuilt quality monitoring system. – The new stove masters/promoters are constantly being monitored until technical perfection is achieved. – Every 15 to 20% of stoves installed by stove masters/promoters are monitored by LSM. – 20% of the reported monitored samples are randomly selected and cross verified by the biomass engineers. – Field Monitoring of the randomly generated samples from the center and analysis.
- 5. • Metallic Stoves(subsidized) – Technical quality checking at company premises. – Third party monitoring of 10% randomly generated stoves at the user household for checking after sales service and functionality of the stoves. Technical quality assurance of stoves
- 6. • Metallic Stoves(cooking and heating) – Selected improved and proven stove (KU design) – Other stove models • Call for testing of various metallic stove designs available in the market (research institutes, organizations, manufacturers) • Best performing, improved and economic stove models were selected. • The selected designs were tuned for meeting user’s expectations from the past learning. • The final product was standardized and disseminated. Selection of new models for dissemination
- 7. • Mud Stoves(portable) – R&D carried out in the center and field for efficient, economic and field acceptable design. – Field testing of the stoves (WBT) – Piloting of the stove (user acceptance) – Reproduction of the best model and mass dissemination Selection of new models for dissemination

Field Testing is conducted by the trained staffs only.
- 9. Standardization in qualitystove testing With the emergence of quality of stove in the international arena AEPC developed national stove testing protocol for wood burning stoves suitable for Nepalese context on January 2009 and was named “Interim National Stove testing Protocol” •Protocol based on Approvecho’s protocol for WBT, CCT and KPT •Publication of Pictorial manual for stove testing at lab and field level. •IAP and emissions were not part of the protocol. Current status: needs to be updated including latest developed emission and IAP measurement standards
- 10. • Supported inestablishment of Biomass stove laboratory at RETS as quality certifying body. • Adaptive research on development of portable rocket stoves for Terai regions through RSCs. • Improvised design for Mud ICS into Rocket Principle at the center. • Improvised efficient MICS model development. Other initiatives towards quality stove development and testing
