Formaldehyde is one of the most thoroughly evaluated substances. In 2014 Formaldehyde was reclassified as a Carcinogen Category 1B. According to the?CLP Regulation, Category 1B substances are presumed to have carcinogenic potential for humans and classification is largely based on animal evidence as opposed to substances falling under Category 1A. The new classification entered into force in June 2014 when published in the Official Journal of the European Union. However, authorities have foreseen a transition period until 1 January?2016, allowing suppliers to adapt to the new classification. The commission decision confirming this can be found in?Commission Regulation 2015/491. After 1 January 2016 the new Classification and Labelling rules must be applied to substances containing 0.1% free formaldehyde or above.
Formacare recommends that free formaldehyde in liquid adhesives should be performed in accordance with EN 1243:2011. The recommendation is valid only for aminoplast resins (for example wood glues and impregnating resins) containing formaldehyde, and/or urea and/or melamine, but excluding etherified adhesives.?
