Check application rounds and updates

The Technical Governance Committee maintains a list of TLUD cookstoves that meet relevant standards and essential consumer protection requirements.

The methods for the BidCarbon Standard Scheme require that PyCCS projects use products from this list.

Manufacturers or nominated agents can apply to add their products to the list by providing documents, including lab tests and certificates, which are then reviewed by our product engineers.

Applying to the approved products list

Application processing times

Full accreditation typically takes a further 2 to 6 months, depending on the completeness of the application.

All applications undergo a thorough and rigorous review process to ensure the quality and safety of products. Manufacturers and importers are encouraged to ensure they submit complete and accurate applications and respond to clarifications quickly, as this helps reduce processing times.

Step 1

Get the product tested and certified to the required Clean Cooking Standards

All TLUD cookstoves must be tested to ISO 19869, ISO 19867-1 and ISO/TR 19867-3 by a testing organisation listed on the Regional Testing and Knowledge Centres (RTKCs).

The certificate must be issued by a testing organisation that is accredited in accordance with ISO 17025.

The Technical Governance Committee requires manufacturers to nominate all importers of their products. Importers are responsible for meeting the manufacturer warranty obligations applicable in the country of final destination.

Importers must keep a record of all serial numbers and make them available to the Technical Governance Committee on request.

Step 4

Additional requirements

TLUD cookstoves may have additional requirements depending on the country or region in which they are installed.

Incomplete applications

Some manufacturers submit incomplete applications, with the belief that they can supply some requirements while the application is in process. We start a check within 10 business days of receiving an application to check that all documentation has been supplied. If the application is incomplete it can’t proceed beyond this stage. We’re also updating our application form to stop incomplete applications being submitted.

Not being able to respond promptly to technical questions

Often, during the technical assessment we have questions about technical aspects of the product. These are usually resolved more quickly if we have a technical contact at the manufacturer. Please supply a technical contact in the application together with the product manager’s details.
