A newly approved standard, ASTM D7338 , Guide for the Assessment of Fungal Growth in Buildings, has been developed to provide a go-to reference for anyone testing for mold in buildings. The new standard was developed by Subcommittee D22.08 on Sampling and Analysis of Mold, part of ASTM International Committee D22 on Air Quality. “The lack of consensus standards in the fungal sampling and analysis…, ASTM Committee D22 Next Meeting:, April 10-13, April Committee Week, Anaheim, Calif., Technical Contact:, Lisa Rogers, Mycometer, Inc., Tampa, Fla., Phone: 813-831-6511; lrogers@mycometer.com, ASTM Staff Contact:, David Bradley, Phone: 610-832-9681; dbradley@astm.org, ASTM PR Contact:, Barbara Schindler, Phone: 610-832-9603; bschindl@astm.org Release #8788

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…

A proposed new ASTM International standard for liquid threats on protective clothing will cover the specific needs of law enforcement officers. The new standard, ASTM WK25965 , Test Method for Liquid Threat Sprayed on a Mannequin, is being developed by Subcommittee F23.30 on Chemicals, part of ASTM International Committee F23 on Personal Protective Clothing and Equipment. Fire and hazardous…

The ability to provide the correct amount of protection is one of the important elements in the development of protective clothing worn by individuals who apply pesticides as part of their jobs. While overprotection in hot climatic conditions can result in heat stress and low compliance, some of the existing design-based requirements can result in too little protection, as material performance…, CONTACT:, ASTM Committee F23 Next Meeting:, Jan. 26-28, 2010, January committee week, San Antonio, Texas, Technical Contact:, Anugrah Shaw, University of Maryland Eastern Shore, Princess Anne, Md., Phone: 410-651-6064; ashaw@umes.edu, ASTM Staff Contact:, Stephen Mawn, ASTM International, Phone: 610-832-9726; smawn@astm.org, ASTM PR Contact:, Barbara Schindler, ASTM International, Phone: 610-832-9603; bschindl@astm.org Release #84 54/Jan2010

Workers in oil refineries, chemical plants, the natural gas industry and other industries that involve flammable or explosive materials need access to rain gear that is also flame resistant. A new ASTM International standard, ASTM F2733 , Specification for Flame Resistant Rainwear for Protection Against Flame Hazards, provides minimum requirements for flame resistant rainwear to be used by…

In the field of personal protective clothing, a temperature rating indicates the lowest acceptable air temperature at which an average person would be comfortable when wearing a certain set of clothing. While manufacturers believe that providing temperature ratings is helpful to consumers when they are comparing garments, there have been different methods of testing for a temperature rating. The…

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…

Honeycomb ceramics, porous with linear hollow channels, are being used worldwide in automotive catalytic converters and as diesel particulate filters for trucks. Flexural testing of this type of ceramics is addressed in a new ASTM International standard, ASTM C1674 , Test Method for Flexural Strength of Advanced Ceramics with Engineered Porosity (Honeycomb Cellular Channels) at Ambient…

New Advanced Ceramics Standards from ASTM Cover Fracture Mirror Size Analysis, Tensile Strength DataSubcommittee C28.01 on Mechanical Properties and Performance, part of ASTM International Committee C28 on Advanced Ceramics, has recently approved two new standards, ASTM C1678 , Practice for Fractographic Analysis of Fracture Mirror Sizes in Ceramics and Glasses, and ASTM C1683 , Practice for Size Scaling of Tensile Strengths Using Weibull Statistics for Advanced Ceramics., ASTM C1678 —Bringing Consistency to Fracture Mirror Size Analysis, Fracture mirror size analysis is a powerful quantitative tool for the interpretation of broken ceramic and glass articles. While this type of analysis can be used to determine the stress in a part at the instant of fracture, inspection and interpretation procedures have often varied, resulting in uncertainty in stress estimates. ASTM C1678, Practice for Fractographic Analysis of Fracture Mirror…, ASTM C1683 —Scaling Strength Values, ASTM C1683, Practice for Size Scaling of Tensile Strength Using Weibull Statistics for Advanced Ceramics, provides methodology to convert fracture strength parameters estimated from data obtained with one test geometry to strength parameters representing other test geometries. Stephen Duffy, chair of civil engineering, Cleveland State University, and C28 member, says that companies producing…
