ATCA is now an a​pproved CARB 3rd party certification body. TPC-12


The Californian Air Resources Board (CARB) have introduced a regulation that restricts Composite Wood Panels (CWP) and products made from them entering the state if they exceed certain limits set for formaldehyde emissions. To ensure that products meet these limits all CWP entering California from January 1 2009 will have to be certified by an external body that they meet the limits.

It is now becoming apparent that there is a need in this region for manufacturers to gain accreditation either because they are exporting directly to the USA or they have customers who convert raw board that ultimately is exported to the USA. We also have anecdotal evidence that distributors want only CARB compliant products entering their supply chain so they don’t have to deal with segregation issues. Additionally there has been some petitioning of the US EPA by green groups for the CARB regulation to be adopted nationally.

The CARB regulation sets limits on the allowable emissions from CWP and it also defines the rules by which compliance to these standards is established. These limits are based on the American large chamber test. Also the regulations become tighter in successive years. Any batch of product which does not meet the limits or does not have certification documents cannot be shipped.

Certification Process

The Airborne Toxic Control Measures (ATCM) have been introduced by the Californian Environmental Protection Agency with the aim of progressively reducing formaldehyde and other emissions from products sold in California.

The requirement is for manufacturers to seek certification under a CARB approved third party certifier (TPC). The TPC is required to test product for formaldehyde emission and also regularly inspect production records and test results at the plant.

ATCA is approved by California Air Resources Board as a Third Party Certifier (TPC) for the purpose of providing regulation to composite wood manufacturers in this Australian and SE Asian region.

Other resources required by the certification body are access to lab facilities to carry out the routine testing for the QC method (desiccator or others), a secondary method - usually a small scale chamber to ASTM D6007 and finally a large scale chamber test to ASTM E1333.
