Process for listing products on www.ectc.org

ECTC members’ products listed in this section undergo a comprehensive peer review process. The positioning of the product is the manufacturer’s sole responsibility; ECTC makes no claims and assumes no liability for products as positioned by the manufacturer. However, a peer group reviews each submittal to ensure the product has been subjected to the appropriate testing by the manufacturer. The following is a summary of the product review process for listings in the Product Selection & Design section of this site.

1. Members must complete an extensive application and provide test reports for all products they would like listed within each perspective performance category.

2. The ECTC Testing and Specifications Committee meets to review the application and supporting data and then recommends whether or not and where to include the product on the chart. The Committee makes a recommendation.

3. If the Testing and Specifications Committee recommends that the product not be listed within the desired category, a detailed response is sent back to the submitting manufacturer highlighting the grounds for rejection and necessary steps to achieve listing in the desired category.

4. If the Testing and Specifications Committee recommends that the product be included, then a ballot is sent to ECTC Directing Membership.

5. Directing Membership approves the ballot and the product is listed.

Each product must go through this entire review process.
