Determining the pressure rating for PVC plastic pipe is a relatively straightforward process because pipe is a cylinder with a uniform wall thickness. However, establishing a pressure rating for PVC fittings is a more complex process, chiefly because there are many sizes, patterns and variations among manufacturers involved. A new ASTM International standard, F 2261 , Test Method for Pressure…

Keeping pipes properly connected is clearly an important aspect of any sewer maintenance system. A new ASTM International standard, F 2561 , Practice for Rehabilitation of a Sewer Service Lateral and Its Connection to the Main Using a One-Piece Main and Lateral Cured-in-Place Liner, has been developed that makes the process of keeping sewer pipelines connected more effective. Practice F 2561 is…

A more efficient method to take asphalt pavement layer temperatures is the subject of a new standard developed by Subcommittee E17.41 on Pavement Management. The document, D 7228 , Test Method for Prediction of Asphalt-Bound Pavement Layer Temperatures, details surface temperature measurement and is based on temperature relationships in the Federal Highway Administration Long Term Pavement…

Many state departments of transportation are collecting traffic data in real time and using it to manage traffic or provide travel information, as part of intelligent transportation systems. Some agencies save and archive this data after its initial real-time use and make it available to other data users, who often know little about how the data was collected or even what is contained in the data…

ASTM International Committee C24 on Building Seals and Sealants is currently working to fill a need for a weatherproofing sealant field test standard. The result, proposed standard WK7800, Guide for a Non-Destructive, Continuous, Field Test of Installed Weatherproofing Sealant, features a field test that has been used by sealant professionals for years, but has not, up to this point, been…

A growing interest in a more durable structure for grease traps has resulted in the development of a proposed new ASTM standard, WK7686, Specification for High Density Polyethylene Grease Trap Interceptor Units. The proposed standard is under the jurisdiction of ASTM Subcommittee F17.26 on Olefin Based Pipe, which is part of Committee F17 on Plastic Piping Systems. "The impetus for developing…

A new ASTM standard developed by Committee F17 on Plastic Piping Systems will be an important step in advancing the use of high density polyethylene pipe in municipal storm sewer applications. The standard, F 2306, Specification for 12 to 60 in. (300 to 1500 mm) Annular Corrugated Profile Wall Polyethylene (PE) Pipe and Fittings for Gravity Flow Storm Sewer and Subsurface Drainage Applications,…
