The abrasiveness of rock plays a crucial role in the performance of any mechanical excavation machines because overall costs are affected by the rate of cutting tool replacement and/or repair and machine downtime. The need for a standard that assists the civil and mining industries in quantifying rock abrasiveness properly and uniformly has been answered by a new ASTM International standard.…

Wet and dry density of soils are important values for geotechnical engineers in determining over-burden stresses, void ratios, maximum compaction and percent compaction of soils. Density value can also aid in the evaluation of soil strength and sensitivity. While reporting on soil density has been part of routine laboratory testing for years, there have been no standards that outlined procedures…

ASTM International has published a new American National Standard, ASTM E2659 , Standard Practice for Certificate Programs. This standard provides much-needed guidance to certificate issuers on how to develop a quality certificate program and to consumers on how to identify such a program. In addition, the standard is designed to serve as the benchmark of quality for industry accreditation of…

No industry standard currently exists that addresses the vacuum sealing requirements of knife-edged flanges for high vacuum applications. Existing international standards focus on interchangeability of the hardware, but do not address the reliability of the seal. ASTM International Committee E42 on Surface Analysis is now working on a proposed standard on the subject, WK21206 , Specification…
