Dual Chamber Gas Analysis for Formaldehyde Analysis According to EN 717-2
The gas analysis method according to DIN EN 717-2 is a quick measuring method in which the formaldehyde emissions of wood based panels are measured for four hours at 60 °C. The formaldehyde emission is indicated in mg/m²h and refers to the unsealed total surface of the test samples (400 mm x 50 mm). The edges of the samples are sealed prior to testing.
Your Benefit
Formaldehyde emission analysis according to EN 717-2 in only a few hours
Approved as alternative test method by the California Air Resources Board (CARB)
Simultaneous measurement of two samples
Process and quality control
Significant correlations with reference methods according to EN and ASTM
Measuring Principle
The filtered and pre-dried airflow in the measuring chamber is 60 l/h. The air with the formaldehyde emitted by the test sample is fed from the measuring chamber into a pair of eight wash bottles with water in which the formaldehyde is filtered for a time period of one hour each. Afterwards, the formaldehyde content is spectrophotometrically determined by means of the acetylacetone method at a wave length of 412 nm.
