ASTM International Committee F17 on Plastic Piping Systems has recently approved a new standard and is currently working on two proposed new standards. The following describes these standards activities., Plastic Piping Systems Committee Completes Latest Standard in Polyamide-11 Series, The use of polyamide-11 (PA-11) thermoplastic pipe to distribute natural gas at pressures up to 200 psig can provide gas distribution companies with a safer, cost-effective option to using steel piping for this application. In order to facilitate the use of PA-11 piping, ASTM International Committee F17 on Plastic Piping Systems has developed a new standard, F 2600 , Specification for…, Proposed ASTM Excess Flow Valve Standard Will Provide Home Protection, Excess flow valves are important safety devices that can protect homes from unattended pipe disconnections and ruptures. A proposed new ASTM International standard, WK12961 , Specification for Excess Flow Valves for Fuel Gas Systems, will cover minimum requirements for excess flow valves that are used in low-pressure applications downstream of a gas utility meter. Current standard F 2138 ,…, Polyethylene Pipe Butt Fusion Standard Under Development by ASTM Plastic Piping Committee, A proposed new ASTM International standard will be useful to gas companies, utilities and pipe manufacturers in qualifying parameters and procedures for new polyethylene pipe material, as well as existing material. The proposed standard, WK12986 , Test Methods for Qualifying Polyethylene Pipe Butt Fusion Joining Parameters and Procedures, is being developed by Subcommittee F17.40 on Test Methods…

ASTM Committee C09 on Concrete and Concrete Aggregates will hold a planning meeting for proposed new standards activity on pervious concrete on Dec. 4 at the C09 meeting in Atlanta, Ga. The committee is especially seeking researchers who have been experimenting with different types of tests for pervious concrete, as well as specifying engineers, concrete technologists and contractors. “Many…

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…

A new ASTM standard, C 1610/C 1610M , Test Method for Static Segregation of Self-Consolidating Concrete Using Column Technique, satisfies a need within the industry for a test method to measure the stability of self-consolidating concrete. The standard is under the jurisdiction of Subcommittee C09.47 on Self-Consolidating Concrete, which is part of ASTM International Committee C09 on Concrete and…

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 proposed new standard currently being developed by ASTM International Committee F01 on Electronics will prove to be useful to the tantalum sputtering target industry. The proposed standard, WK9490, Test Method for Reporting Crystallographic Orientation of Sputtering Target Materials, is under the jurisdiction of Subcommittee F01.17 on Sputter Metallization. "The tantalum sputtering target…
