Voluntary Consensus Standards Update; Formaldehyde Emission Standards for Composite Wood Products

The Environmental Protection Agency (EPA) is proposing to update the incorporation by reference of several voluntary consensus standards in the Agency's formaldehyde standards for composite wood products regulations under the Toxic Substances Control Act (TSCA) due to the standards having been updated or superseded by the issuing organizations. These new standards primarily update test methods and product standards concerning composite wood products that use formaldehyde. EPA is also proposing to conform these updated standards in the scope and definitional sections in the final rule and to incorporate by reference a new small scale quality control chamber test method, similar to current methods already incorporated by reference.
