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 International Committee C24 on Building Seals and Sealants invites interested parties to participate in the development of a proposed new standard that will use photographs to illustrate various types of sealant failures. WK11731 , Guide for Diagnosing Sealant Failure by Comparison to Reference Photographs, is under the jurisdiction of Subcommittee C24.10 on Specifications, Guides and…

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…

Verifying the results of application software used to calculate the mechanical properties of materials is the subject of a new standard developed by ASTM International Committee E08 on Fatigue and Fracture. The new standard, E 2443, Guide for Verifying Computer-Generated Test Results Through the Use of Standard Data Sets, is under the jurisdiction of Subcommittee E08.03 on Advanced Apparatus and…

Many structures, such as aircraft or other lightweight vehicles, are made from thin-ductile structural materials that exhibit low crack-front constraint, which allows for extensive plastic yielding of the material around a crack front. However, many current standards, such as E 399, Test Method for Linear-Elastic Plane-Strain Fracture Toughness K Ic of Metallic Materials, or E 1820, Test Method…

Representatives of ASTM International will visit the campus of Southern Methodist University (SMU) in Dallas, Texas, on the evening of Nov. 9, 2005, for an hour-long presentation to university students interested in the field of fatigue and fracture. The session will focus on the technical standards currently in use by this discipline as well as the ability of students and professionals to be…

ASTM International Committee F34 on Rolling Element Bearings is seeking participation in a new activity on measuring the cleanliness and wetability of bearing components. Because aerospace customers currently use many different methods of testing ball bearings, the goal of the activity is to work toward a consistent method for measuring cleanliness and wetability, as well as to analyze the…

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…
