Description:

The ESTE test program measured the mold resistance of Armacell AP Armaflex Black insulation. Tests for emissions of VOCs and formaldehyde were also performed. AP Armaflex Roll Insulation is a black flexible closed-cell, fiber-free elastomeric thermal insulation. The expanded closed-cell structure makes it an efficient insulation for ductwork, large piping, fittings, tanks and vessels. AP Armaflex products are made with Microban® antimicrobial product protection for added defense against mold on the insulation. Mold resistance testing was performed following the guidelines outlined in ASTM 63299. A major concern was the way growth on the different materials was evaluated. ASTM 63299 evaluates growth quantitatively as the endpoint. Selecting the "correct" test organism is critical. Two fungi were used as test organisms, Aspergillus versicolor and Stachybotrys chartarum. Clear plastic desiccators served as the static environmental chambers. A saturated-salt solution of potassium chloride was used to maintain the humidity of the 85% ERH chamber. Sterile water was used for the 100% ERH chamber. Temperature was maintained at room temperature.
