The US Environmental Protection Agency (EPA) has imposed the latest limit on formaldehyde emissions from hardwood plywood, medium density fiberboard and particleboard. These products have long been incorporated into the "formaldehyde standard method for composite wood products in 2010", which took about five and a half years ago. EPA said it has partnered with the California Air Resources Board to ensure that its final rules are consistent with California's current regulations for composite wood products.
The above rules are made in the United States after the publication of the Federal Register, all of the hardwood plywood, particleboard, medium density fiberboard, and medium-density fiberboard, which are manufactured, sold, supplied, offered for sale or manufactured in veneer or composite core in the United States. Manufactured products (including composite wood products, including those used or installed in prefabricated houses) must meet the following release criteria, which are the same as the CARS ATCM Phase II standard for the California Air Resources Committee's Toxic Substances Airborne Control Measures (CARB ATCM).
- The formaldehyde emission of hardwood plywood made from single or core composite core shall not exceed 0.05 ppm;
- Formaldehyde release of medium density fibreboard should not exceed 0.11ppm;
- Formaldehyde in the body of the density of formaldehyde release should not exceed 0.13ppm;
- The release of formaldehyde from the particleboard should not exceed 0.09 ppm.
Hardwood plywood is defined only for veneer and indoor use. To qualify for exemption, the manufacturer of the laminate must keep records to prove that they are eligible. Seven years after the final rule is published, if the product is not exempt from the definition of hardwood plywood, the manufacturer of the laminate must test its product to ensure compliance with formaldehyde release standards for hardwood plywood.
The above-mentioned release standards are applicable either in the form of veneers or components or in composite wood products embedded in finished articles.
After the release standard comes into effect, unless the composite wood products are subject to special exemption, they must be certified in the veneer or in the embedded parts or in the finished product before they can be imported, sold, supplied, offered for sale or manufacture. In order to qualify and maintain certification, veneer manufacturers must establish quality assurance / quality control plan, regular product quality control test, by the US Environmental Protection Agency approved third-party certification body quarterly or supervision of formaldehyde Release test.
The US Environmental Protection Agency clarifies in another question and answer session that although the finished product is not subject to formaldehyde emission testing and certification, the components of the finished product, if considered to be a regulated composite wood product, must be tested to ensure that Meet the release criteria. Composite wood products If the components of the finished product, the manufacturer must save the document to prove that the product has been qualified. EPA also said that the formaldehyde emission test should be veneer manufacturers and third-party certification bodies. It is the responsibility of the processor and the retailer to ensure that only the composite wood products that meet the standards are purchased.
The veneer or bundled veneer, which is sold, supplied or offered in the United States, must mark the name of the veneer manufacturer, batch number, EPA's "Toxic Substances Control Act" Part VI Third Party Certification Body (EPA TSCA Title VI TPC) , And that the product has been certified to comply with the statement of Part VI of the Toxic Substances Control Act. If the composite wood panels are not individually marked, their manufacturers, importers, distributors, processors or retailers will use a method sufficient to identify veneer suppliers (such as color coded edge markers) to link the data on the label to the product The This information must be made available to prospective customers upon request. Labels can be stamped, listed or stickers, etc.
Importers, processors, distributors and retailers must take reasonable precautions to ensure that they are sold, supplied, offered for sale or sale of composite wood products, whether veneer, components or finished products, are suitable for release standard. The importer must demonstrate that they have taken reasonable precautions to keep the bill of lading, invoice or similar document for three years, including a written statement by the supplier that the composite wood product, component or finished product complies with the "Toxic Substances Control Act" VI, or before the final rule is published 1 day after the publication of the Federal Register and ensure that certain records are available to the US Environmental Protection Agency within 30 days upon request.
Veneer manufacturers must also keep production records for three years, however, if veneer manufacturers producing composite wood products are allowed to reduce the number of tests or exempt from third party verification, it must always retain the initial reduction in the number of tests or exempt from third parties Verification and other qualifications to prove.
