The NSF Flushable Consumer Products Program utilizes the INDA/EDANA Flushability Guidelines as a basis for testing under this program.
Based in Cary, North Carolina, INDA is the Association of the Nonwoven Fabrics Industry. Based in Brussels, Belgium, EDANA is the international association serving the nonwovens and related industries.
In 2008, after four years in development, INDA and EDANA introduced "The Guidance Document on the Flushability of Nonwoven Consumer Products." The document contains guidelines representing the first-ever initiative to provide companies with a comprehensive framework for testing disposable products to determine their flushability. Today, this is the accepted industry document for testing flushability claims.
Many manufacturers are curious to know which tests will be required for their specific product type. Unfortunately, due to the varying complexity of these products, there is no "one size fits all" answer to these questions, as the INDA/EDANA Flushability Guidelines determine which tests should be conducted.
However, all products must generally undergo a toilet bowl and drainline test, a dispersability test, a column settling test and aerobic and anaerobic disintegration tests. These tests encompass the various US and European-size pathways that a product may follow in the wastewater system.
