PARAMETERS:
| - |
Sample Size: Three @ 48” x 67.25” or 49”
x 66” equaling 134.5 sq.ft. |
| - |
Chamber Dimensions:
149.5” x 124.5” x 96” Volume: 1.034
cubic ft. |
| - |
The test samples
were either dead stacked with cover boards on the
top and bottom or air tight wrapped in 6 mil plastic. |
| - |
The samples were
conditioned for seven days prior to testing at 70°
to 80° F and 45% to 55% relative humidity. They
were spaced approximately 6 inches apart. The formaldehyde
background level was 0.1 parts per million or less. |
| - |
Temperature in the
chamber during the test varied between 75° and
79° F. Relative humidity was maintained between
46% and 54%. The Air Exchange Rate was 0.5+/-0.05
air changes per hour. The chamber is activated under
positive pressure. |
| - |
The formaldehyde
background level in the chamber was 0.02 parts per
million or less. |
| - |
The air-sampling
rate was 1.0 liter per minute at 60+/-2 minutes. |
| - |
The spectrophotometer
is a Bausch&Lomb Spectronic 21D.
