Taking a tape-lift sample is one of the main practices used by indoor environmental quality investigators for detecting whether mold structures (for example, spores and hyphae) have either settled onto or colonized the surface. Despite the popularity of the method, there can be significant inconsistency in how tape lifts are collected. A new ASTM standard, ASTM D7910 , Practice for the Collection…, ASTM Committee D22 Next Meeting:, Oct. 5-8, 2014, October Committee Week, New Orleans, La., Technical Contact:, John M.

A new standard, ASTM D7886 , Practice for Asbestos Exposure Assessments for Repetitive Maintenance and Installation Tasks, will aid those testing asbestos exposures by quantifying such exposure levels. Regulations set forth by the U.S. Occupational Safety and Health Administration require that worker exposure to asbestos be determined with a “high level of certainty.” “ASTM D7886 overcomes the…, ASTM Committee D22 Next Meeting:, Oct. 5-8, 2014, October Committee Week, New Orleans, La., Technical Contact:, Andrew F.

Gaseous hydrogen fluoride is a harsh respiratory irritant; the inhalation of hydrofluoric acid mists causes severe lung damage in exposed workers. A proposed new ASTM standard, WK38734 , Test Method for the Determination of Particulate Fluorides and Hydrofluoric Acid Using Filter Sampling and Suppressed Ion Chromatography, will be used to prevent overexposure of hydrofluoric acid/hydrogen…, ASTM Committee D22 Next Meeting:, Oct. 5-8, 2014, October Committee Week, New Orleans, La., Technical Contact:, Dietmar Breuer, IFA, Sankt Augustin, Germany, Phone: +49 (0) 2241 231-2533; dietmar.breuer@dguv.de , ASTM Staff Contact:, Jeffrey Adkins, Phone: 610-832-9738; jadkins@astm.org , ASTM PR Contact:, Barbara Schindler, Phone: 610-832-9603; bschindl@astm.org Release #9585

While monitoring air quality is important in many situations, a variety of different quantitative passive samplers are available for such work. A proposed new ASTM standard, ASTM WK45755 , Guide for Selection of Quantitative Passive Samplers for Volatile Organic Compounds in Air, will help users decide which air sampler type will best suit their needs. ASTM WK45755 will cover issues such as the…, ASTM Committee D22 Next Meeting:, Oct. 5-8, 2014, October Committee Week, New Orleans, La., Technical Contact:, Nicola Watson, Markes International, Loveland, Ohio, Phone: 513-488-6161; nwatson@markes.com , ASTM Staff Contact:, Jeffrey Adkins, Phone: 610-832-9738; jadkins@astm.org , ASTM PR Contact:, Barbara Schindler, Phone: 610-832-9603; bschindl@astm.org Release #9578

A new ASTM International standard is focused exclusively on testing soil for asbestos. ASTM D7521 , Test Method for Determination of Asbestos in Soil, was developed by Subcommittee D22.07 on Sampling and Analysis of Asbestos , part of ASTM International Committee D22 on Air Quality . According to Alan Segrave, division manager, laboratory services, Bureau Veritas, and an ASTM D22 member, many…, ASTM Committee D22 Next Meeting:, April 14-17, April Committee Week, Indianapolis, Ind., Technical Contact:, Alan M.

A new ASTM International practice provides a standard for preparing a mixture of cement paste that will simulate the shearing experienced by the cement paste in concrete. The new standard, ASTM C1738 , Practice for High-Shear Mixing of Hydraulic Cement Pastes, was developed by Subcommittee C01.22 on Workability , part of ASTM International Committee C01 on Cement . According to Chiara Ferraris,…

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…

Rapid hardening hydraulic cements are used in a variety of applications in which reduced cementitious contents are desired or early service is needed. Included among these applications are paving, construction, stucco, mortar and block. A newly approved ASTM International standard covering these cements, ASTM C1600/C1600M , Specification for Rapid Hardening Hydraulic Cement, has been developed by…, Type URH, —ultra rapid hardening, for use where ultra high early strength is desired;, Type VRH, —very rapid hardening, for use where very high early strength is desired;, Type MRH, —medium rapid hardening, for use where mid-range rapid hardening, high early strength is desired; and, Type GRH, —general rapid hardening, for use when the higher strength properties of Type VRH or a Type MRH cement is not required. “ASTM C1600 lists minimum requirements for compressive strength, setting time, shrinkage and soundness (autoclave expansion),” says Hicks. “Optional specifications for sulfate expansion, alkali silicate reactions with aggregates, heat of hydration and expansion in water are also…
