Application

Non-destructive on-site emission testing

Use FLEC® to sample emissions directly from installed floors, walls and ceilings while keeping the tested surface intact.

Measure where the material is installed

The compact FLEC Cell creates a controlled measurement area on a material surface. This makes it possible to investigate emissions in real buildings without removing a sample for chamber testing.

For vertical surfaces and ceilings, the FL-0210 FLEC Telescope Kit helps position the cell securely. A controlled supply of clean air and suitable pumps and sampling tubes complete the measurement setup.

Typical on-site applications

  • Flooring and floor treatments
  • Wall and ceiling finishes
  • Paints, coatings, adhesives and sealants
  • Source identification in occupied or newly completed buildings

A controlled on-site workflow

  1. Define the surface, measurement objective and target compounds.
  2. Position and seal the FLEC Cell without damaging the installed material.
  3. Supply clean, conditioned air and verify the required flows.
  4. Collect samples using suitable tubes and analyse them with the selected VOC or carbonyl method.

Interpret measurements in context

NT BUILD 484 treats on-site measurements as semiquantitative because conditions in buildings can be difficult to control. Record the surface, location, temperature, humidity and sampling conditions. A surface-emission result helps investigate a potential source; it does not by itself establish whole-room air quality or occupant exposure.

Relevant standards

NT BUILD 484 describes on-site measurements with FLEC. ISO 16000-10 and ASTM D7143 acknowledge on-site use in principle, but do not specify the field procedure. Select and document the complete sampling plan for the project.
