Modified ASTM E814/UL 1479 Fire Resistance on an air krete® wall panel

Tested: February 21, 2008 VTEC #100-2862

Results:

The initial ambient temperature was 57°F.

Hose Stream Test: No holes formed in the unexposed side of the

sample after being exposed to the hose stream for 24 seconds.

The sample met the acceptance criteria of the “F Rating” for 120

minutes per ASTM E814/UL 1479 specifications.

A Microbial Resistance Evaluation of Indoor Materials

air krete® Insulation Sample

Executive Summary / Project Description

Air Quality Sciences, Inc. (AQS) is pleased to present the results of its microbial resistance evaluation of air krete's indoor material identified as “ air krete® Insulation Sample”. AQS conducted this study using a microbial test protocol following the requirements of ASTM Guideline D 6329-98 (1). This ASTM method is established to study indoor materials for their ability to support mold growth. Testing of the indoor material was conducted using static environmental chambers operating at 75% humidity(considered a *high normal” for indoor commercial spaces) and 95% humidity (considered an extreme moisture condition within buildings). air krete's indoor material was inoculated with two representative indoor molds, Stachvbotrvs chartarum and Eurotium amstelodami, and growth rates were measured over a three-week period as the materials were exposed in the two humidity environments. Mold growth is considered significant if it exceeds 20% of the initial baseline levels. Test methodology and results are given in the attached summary reports.

Results:

Results show that the “ air krete® Insulation Sample” was resistant to mold growth at both 75% and 95% relative humidities. Neither molds were found to amplify in the materials at either humidity.
