Many ship owners and operators repair ship structures with temporary steel patches known as doublers. The U.S. Coast Guard and Navy, as well as other maritime authorities, usually allow such patches until the ship’s next inspection period, which can be as long as three to five years from the date of repair. Despite this situation, there is not currently a standard for repairing steel hull ships…, ASTM Committee F25 Next Meeting:, May 17-19, 2011, May Committee Week, Anaheim, Calif., Technical Contact:, Chao H.

Air permits from regulatory agencies, such as the U.S. Environmental Protection Agency (USEPA), often require the measurement of a plume's opacity as the plume is emitted from a stationary point source (for example, smokestacks) in the outdoor ambient environment. While such opacity is often visually measured by human observers as “certified smoke readers,” an opacity measurement method using…

The measurement of acid mist is becoming increasingly important due to recent actions taken by the U.S. Environmental Protection Agency on fine particles (2.5 micrometers in diameter and smaller) that are unhealthy to breathe. ASTM International Committee D22 on Air Quality is currently working on a proposed standard for measuring acid mists that come from combustion sources, WK22846 , Test…
