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…

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…

ASTM International Committee C26 on Nuclear Fuel Cycle has approved two new standards, both under the jurisdiction of Subcommittee C26.05 on Methods of Test. All interested parties are invited to participate in the standards developing activities of Committee C26. ASTM International standards are available for purchase from Customer Service (phone: 610/832-9585; https://www.astm.org/contact )…, ASTM C 1637 , Test Method for the Determination of Impurities in Plutonium Metal: Acid Digestion and Inductively Coupled Plasma-Mass Spectroscopy (ICP-MS) Analysis, The approval of C 1637 is part of Subcommittee C26.05’s project involving the approach to keeping the analytical methodology used for determining specifications for nuclear materials up to date. This project began in 1990 when the subcommittee decided to develop separate standards from methods that were part of larger multi-methods materials specification standards. Once the new test methods…, ASTM C 1638 , Guide for the Determination of Iodine-129 in Uranium Oxide, Guide C 1638 covers the determination of iodine-129 in uranium oxide by gamma-ray spectrometry. Users may include U.S. Department of Energy sites that are dispositioning excess uranium to waste sites. Although there is no specification for the levels of I-129 in fuel, waste disposal sites may set limits due to the potential mobility of iodine in the environment. This guide may be used to ensure…
