Formaldehyde E1 emissions requirements – Untreated solid wood

Testing for formaldehyde is not required for untreated solid wood where no formaldehyde containing binders, resins, adhesives, coatings, or chemical treatments have been used in the processing or manufacture.

In such cases, a formaldehyde emissions test report is not required. However, the assessor must obtain confirmation from the manufacturer/supplier that:

• the product is solid, untreated timber
• no formaldehyde has been used as described above
