When fasteners penetrate roofing or waterproofing products as a planned part of installation, it is expected in some cases that the product will resist water migration at the point of penetration. A new ASTM International standard, D7349 , Test Method for Determining the Capability of Roofing and Waterproofing Materials to Seal Around Fasteners, addresses this situation. ASTM D7349 was developed…

ASTM International Committee E35 on Pesticides and Alternative Control Agents has begun work on the latest in a series of standards on biofilm. The proposed new standard, WK17813 , Test Method for Quantification of a, Pseudomonas aeruginosa, Biofilm Grown with Low Shear and Continuous Flow Using a Drip Flow Biofilm Reactor, is being developed by Subcommittee E35.15 on Antimicrobial Agents. According to Darla M. Goeres, senior research engineer, Center for Biofilm Engineering, and E35 member, biofilm is defined as microorganisms living in a self-organized cooperative community. These communities, which are embedded in slime and can be…, Pseudomonas aeruginosa, Biofilm Grown with High Shear and Continuous Flow Using CDC Biofilm Reactor; and E2196 , Test Method for Quantification of a, Pseudomonas aeruginosa, Biofilm Grown with Shear and Continuous Flow Using a Rotating Disk Reactor) is that biofilm is grown under low fluid shear close to the air/liquid interface and that the drip flow reactor is a plug flow reactor system, resulting in biofilm that is visible to the naked eye and smooth and slimy in appearance. Biofilm generated in a drip flow reactor could represent those found in a wide spectrum of…
