ASTM International Committee F17 on Plastic Piping Systems has recently approved a new standard based on two important documents originally developed by the Plastics Pipe Institute in the mid-1990s. The new ASTM standard, F 2620 , Practice for Heat Fusion Joining of Polyethylene Pipe and Fittings, is under the jurisdiction of Subcommittee F17.20 on Joining. According to Jim Craig, industry…

Municipalities, specifying engineers and piping system owners are now requiring tighter criteria for piping products. ASTM International Committee F17 on Plastic Piping Systems has responded by developing two new standards that answer the call for more detailed criteria within the industry. Both of the new standards, F 2487 , Practice for Infiltration and Exfiltration Acceptance Testing of…

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 Subcommittee A01.19 on Sheet and Strip Steel has made three significant changes to ASTM standards under its jurisdiction. The changes are: • Reporting of boron levels made mandatory; • Changes to size limitations of general requirements and product standards for hot rolled material; and • Addition of grades 90 and 100 for hot rolled sheet and strip products. Subcommittee A01.19…, Boron Reporting, Boron is often added to low carbon steels to achieve lower hardness and increased formability; however, the mechanical properties of cold reduced and annealed material produced from hot rolled coils containing boron are affected by its presence. The differences may or may not be desired, but the effects are important and cold rolled steel manufacturers need to be informed of the presence of…, Size Limitation Changes, The general requirements for hot rolled sheet and strip products are spelled out in Standards A 568/A 568M , Specification for Steel, Sheet, Carbon, Structural, and High-Strength, Low Alloy, Hot-Rolled and Cold-Rolled, General Requirements for, and A 635/A 635M , Steel, Sheet and Strip, Heavy-Thickness Coils, Hot-Rolled, Carbon, Structural, High-Strength Low-Alloy, and High-Strength Low-Alloy…, Ultra-High Strength Steel Grades, ASTM standards A 1011/A 1011M and A 1018/A 1018M were changed to include grades with 90 and 100 ksi [620 and 690 MPa] minimum yield strength. These grades have the designation ultra-high strength (UHSS) as a way to differentiate them from the high strength low alloy with improved formability (HSLAS-F) designation. The UHSS grades may achieve their high strength by some measure of transformation…

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…

Dried blood represents the greatest challenge to cleaning surgical instruments. To meet this challenge, ASTM International Committee D12 on Soaps and Other Detergents has developed a new standard, D 7225 , Guide for Blood Cleaning Efficiency of Detergents and Washer-Disinfectors. The new guide is under the jurisdiction of Subcommittee D12.16 on Hard Surface Cleaning. Water-soluble components of…

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…
