Japanese Agricultural Standard (JAS) for Formaldehyde Emission

Japanese regulation for formaldehyde emissions from wood panels is widely considered the most stringent in the world. Their JAS standards for plywood and Structural Panels (OSB) do not directly specify a limit for formaldehyde emissions.

However, panels meeting the F**** standard for formaldehyde emissions (the most stringent requirement level) are required to have an average emission level below 0.30mg/l as tested to Japanese Standard JIS A 1460.  APA PS 1 and PS 2 panels easily meet F**** requirements.

California Air Resource Board (CARB) measures on formaldehyde release

APA member products are exempt from the Airborne Toxic Control Measure to Reduce Formaldehyde Emissions from Composite Wood Products.  Section 93210 (c) (8) of the measure specifically states that composite wood products does NOT include:.

  • Structural plywood as specified in the Voluntary Product Standard – Structural Plywood (PS 1-09)
  • Structural panels as specified in the Voluntary Product Standard – Performance Standard for Wood-Based Structural-Use Panels (PS 2-10 – sometimes designed by APA on its panels by APA’s own Performance-Rated Panel Standard – PRP 108)
  • Structural composite lumber (LVL) specified in Standard Specification for Evaluation of Structural Composite Lumber products (ASTM D 5456-06)
  • Oriented strand board
  • Prefabricated wood I-joists as specified in Standard Specification for Establishing and Monitoring Structural Capacities of prefabricated Wood I-Joists (ASTM D 5055-05)

The CARB regulation was used as the basis for the Federal (US National) Regulation that comes into effect in 2013, therefore, the same exemption exists for the Federal (US National) formaldehyde provisions.
