The paper discusses the development of a framework for testing products used indoors for appropriate environmental attributes, as part of EPA's Environmental Technology Verification (ETV) program. Test protocols are being established for products that fit into three categories: products that have reduced emissions because of pollution prevention efforts, products that control contamination, and products that provide instrumentation for indoor environment measurements. Stakeholder groups of industry, government, and other interested organizations provide input and review the protocols. The program is addressing quality assurance and laboratory proficiency issues necessary to provide consumers with reliable information. As a final step, the protocols are verified and transferred to private programs.
