Germany has announced a new testing standard DIN EN 16516 for formaldehyde emission of wooden furniture. The standard will come into effect on January 1, 2020.

Appendix 1 of the German chemical prohibition regulations (chemverbotsverordnung, chemverbotsv) limits formaldehyde emissions from furniture containing wood furniture, both coated and Uncoated (particleboard, joinery board, plywood and fiberboard). More than 0.1 ml / m3 (PPM). This restriction also applies to the entire piece of furniture containing wood furniture.

In November 2018, bundesministeriumf ü r Umwelt (naturschutz und nuklare Sicherheit, BMU) published DIN EN 16516 as a new test standard for formaldehyde emission (indoor) of coated and uncoated wood materials under the “Prohibition of chemicals regulations”.

This test standard is published in the Federal Register (bundesanzeiger, Banz at 26.11.2018 B2), which allows the existing DIN EN 717-1 method to be used simultaneously with the new method, but requires the concentration value of formaldehyde in DIN EN 717 – 1 multiplied by factor 2 (2). It also allows EN ISO 12460 Part 3 and Part 5 standards to be used only for correlation in production control under certain preconditions.

According to the test standards, the following methods are only valid before December 31, 2019:

·Bundesgesundheitsblatt 34,10 (1991), pp. 488-499, test methods for products made from wood-based materials and wood-based materials

·DIN EN 717-1 wood based panels – Determination of formaldehyde emission – Part 1: formaldehyde emission by chamber method as a test standard for indoor emission measurement of all wooden furniture

·EN ISO 12460-3 wood based panels – Determination of formaldehyde emission – Part 3: gas analysis as a derivative of raw plywood and coated boards

·EN ISO 12460-5 wood based panels – Determination of formaldehyde emission – Part 5: extraction method (called perforation method) as derivation method of raw particleboard and raw fiberboard

Using DIN EN 16516 and DIN EN 717-1 to multiply the formaldehyde concentration by 2, the indoor formaldehyde emission measurement will take effect on January 1, 2020.

The change of testing standard comes from the research projects of Federal Environment Agency and Federal Institute of materials (BAM), in which formaldehyde emission measurement of wooden furniture should adapt to more realistic conditions.

The following table summarizes the key points of these two chamber methods.

The entry into force of this regulation has no effect on the CE certification of construction products, but the export of wood-based panel products to Germany must prove that the products conform to the “E1 level” defined in the new regulation, i.e. the test results of adopting two times of the test value of the climate box method or the test method according to en 16516 (set load rate of 1.8 m 2 / m3, air change rate of 0,5 / h) are less than 0.1ppm This is equivalent to a substantial increase in the formaldehyde limit of the product (from 0.1ppm to 0.05ppm).
