We Provide Emissions Testing to
Determine the Type and Concentration of Chemical Compounds Potentially
Off-Gassed Into the Indoor
Environment |

How to Get Your Products Certified
| 1 |
Manufacturers submit a material sample or a finished product for testing to MAS
(dependant upon the specific test method or reference standard being used) along with a
chain of custody. |
| 2 |
Once received the sample is prepared and loaded into one of 3 standard chamber sizes –
small (53 liter), intermediate (1 cubic meter) or large (28 cubic meters). |
| 3 |
Conditioned air is then passed through the chamber on a continuous basis at a set rate
during chemicals emitted from the core and surface areas of the sample are off-gassed
into the air. At set intervals air samples are drawn from the chamber and analyzed for
VOCs to determine compound type and concentration. |
| 4 |
Emission factors for each VOC compound of interest are calculated for the tested sample
at each sampling interval. Expectant airborne concentrations are then calculated for the
sample based on surface area and a specified ventilation rate typical of the environment
where the material/product would be of used. This data is then compared to a recognized
standard/regulatory limit. Extrapolations, material bracketing and scaling are possible for
extended time periods/varying conditions, broader product line certification and
composite testing respectively. |
