Innovations in the equations and other analytical tools that engineers have used when designing close-fit liners for plastic pipe have led to a need for a new standard for design calculations. This need will be met by a proposed new ASTM International standard, ASTM WK29237, Practice for Design Calculations of Close-Fit Liners. The proposed new standard is being developed by Subcommittee F17.67…

Trona, or sodium sesquicarbonate, is a fine mineral powder that has proven to be effective at removing acid gases from air emissions. While trona can be a useful component of air pollution control systems, it can be difficult to handle, particularly when moisture is present. A proposed new ASTM standard will present a repeatable, precise and accurate test method for analyzing moisture levels in…, ASTM Committee E01 Next Meeting:, Nov. 14-17, November Committee Week, San Antonio, Texas, Technical Contact: J, ames D.

Thermoplastic corrugated stormwater chambers are similar to other types of plastic piping systems in that they are subjected to significant live loads from surface traffic as well as dead loads from earth cover. However, differences in construction — specifically, the fact that chambers are open-bottomed arches — necessitate an understanding of how corrugated stormwater chambers behave…
