ANSI A208.2 PDF

The standard, which covers physical and mechanical properties and dimensional tolerances as well as formaldehyde emission limits, was developed through the efforts of the Composite Panel Association CPA, see sidebar , producers, users, and general interest groups. Current membership collectively represents over 95 percent of total North American manufacturing capacity. CPA collects, analyzes, and reports industry statistics on a monthly and annual basis for such areas as shipments, plant capacity, safety performance, end-uses and international trade. The association also offers extensive laboratory testing services for both members and non-members, and coordinates third-party certification programs through its internationally recognized Grademark Certification Program.

The standard, which covers physical and mechanical properties and dimensional tolerances as well as formaldehyde emission limits, was developed through the efforts of the Composite Panel Association CPA, see sidebar , producers, users, and general interest groups.

Current membership collectively represents over 95 percent of total North American manufacturing capacity. CPA collects, analyzes, and reports industry statistics on a monthly and annual basis for such areas as shipments, plant capacity, safety performance, end-uses and international trade.

The association also offers extensive laboratory testing services for both members and non-members, and coordinates third-party certification programs through its internationally recognized Grademark Certification Program. All EPP-certified products must contain percent recycled or recovered fiber content.

Further, these products must meet industry emission standards. Products meeting the criteria are labeled with the program's EPP certification logo. The CPA www. Published semi-annually, Second Wave is the association's magazine geared towards architects, designers, builders and specifiers.

Specifications identified in the standard include physical and mechanical properties, dimensional tolerances, and formaldehyde emission limits. For example, the U. Department of Housing and Urban Development HUD requires the physical and mechanical properties of manufactured home decking to be third-party certified. Many building code jurisdictions require the physical and mechanical properties of particleboard underlayment and stair tread to be third-party certified.

HUD requires third-party certification of formaldehyde emissions for particleboard used in mobile homes. Approximately percent of the typical composite panel is wood.

The rest consists of resin binders, additives, and water. The adhesive resin most often used by the North American composite panel industry is UF. This resin is strong, colorless, economical, and provides performance criteria specified for most interior uses. The "formaldehyde" used in UF resins is a colorless chemical that is part of a large family of "volatile organic compounds" VOCs -those that become a gas at normal room temperature.

Over the past 15 years, technology has significantly reduced the free formaldehyde, which contributed to emissions. Panels produced today, on average, emit only about one-sixth as much formaldehyde as those produced in the early s. ANSI A These include emission limits of 0. Emission limits are based on values determined under specified conditions in a standard large chamber with product loading ratios of 0.
