Wood products targeted by CSA emission standard

The Canadian Standards Association (CSA Group) has released its first edition of CAN/CSA-O160, a formaldehyde emissions standard for composite wood products such as MDF, tMDF, plywood and particleboard.

The standard is intended to harmonize with the existing California Air Resources Board’s Airborne Toxic Control Measures (ATCM) 17 CCR relating to responsibilities of manufacturers and third party certifiers.

The standard does not apply to curved plywood, hardwood plywood with a lumber core or non-composite core material, finger-jointed lumber and certain structural wood products made with moisture resistant adhesives.

The purpose of the standard is to limit formaldehyde emissions from composite wood panels offered for sale for use in Canada. It specifies the requirements for product sample collection, emissions testing, marking, and labeling, and sets maximum emission limits.

The standard will allow users to either comply with the standard labelling “Complies with CAN/CSA-O160” or participate in a certification program that would allow labelling as “Certified to CAN/CSA O160.”
