The gas analysis method according to EN ISO 12460-3 is a method to determine the formaldehyde release during factory production control. The dimensions of the test piece are 400 mm x 50 mm x board thickness. The edges are sealed prior to testing. The test piece is exposed to a flow of cleaned, dried and heated air (60 °C, 60 l/h) for four hours. The formaldehyde emitted by the test piece into the air flow is trapped in water and analysed photometrically. The results are indicated in mg/m² h and refer to the unsealed surface of the test piece.
- Determination of the formaldehyde release according to EN ISO 12460-3
- Alternative small-scale quality control test method approved by the California Air Resources Board (CARB)
- Intuitive operation
- Large 10” display
- Simultaneous measurement of two samples
- Chambers are operated independently
- Immediate test start by programmable heating
- Data export via USB interface
- Remote service possible via GreCon SATELLITE
- Quality control by participation in LabCheck round robin tests
- For R&D or future amendments of the standard: flexible configuration of air valves and modification of the test temperature possible
A constant flow (60 l/h) of cleaned and dried air with a temperature of 60 °C is led through the test chamber. The test piece in the chamber emits formaldehyde into the air flow. The air/formaldehyde mixture is led through wash bottles filled with distilled water. The emitted formaldehyde is solved and trapped in the water. After four hours, the amount of formaldehyde in the water is determined photometrically.
