Mexico Proposes a Standard for Formaldehyde Emissions in Particleboard and Fiberboard
SAFEGUARDS | Hardlines NO. 101/16
On April 19, Mexico published a Proposed Official Mexican standard PROY-NOM-203-SCFI-2015  which establishes the maximum permissible emission and formaldehyde content in particleboard wood and fibreboard timber made of urea formaldehyde and the products made these types of boards. According to the new standard, particleboard and fibreboard and products made those materials will require testing and certification to the formaldehyde limits from the standard. The standard applies to both domestic and imported composite wood products.
The standard treats the limits for content and emissions as equivalent and either standard may be used to demonstrate compliance. The limits are shown in Table 1 below. Formaldehyde emissions are measured in a chamber by Mexican Standard NMX-C-462-ONNCCE Chapter 7.8. The formaldehyde content is measured using Mexican Standard NMX-C-462-ONNCCE Chapter 7.9 which yields a result in mg / 100 grams of dry wood mass.
Comments will be accepted for 60 days from the date of publication in the Diario Oficial de la Federación.
TABLE 1: Emissions or allowable maximum levels of formaldehyde in particle board and wood fiber board manufactured with urea and formaldehyde in products made with this type of boards.
|Wood particle board||Fiberboard > 8mm thick
||Fiberboard ≤ 8 mm thick
|Emission ppm||Content mg / 100g||Emission ppm||Content mg / 100g||Emission ppm||Content mg / 100g|
