ASTM Committee C27 Update

Making Progress in the Industry

ASTM Committee C27 Chairman’s Report

By Dean A. Frank, P.E.

Dean Frank is chairman of ASTM Committee C27

ASTM Committee C27 recently created a new subcommittee dedicated to precast concrete products for stormwater management. This new subcommittee was given the designation C27.70 and is chaired by Mike R. Miller, international sales manager for Press-Seal Gasket Corp. of Fort Wayne, Ind.

The C27.70 subcommittee held an organizational meeting during the December ASTM International Committee Week in Atlanta and discussed the following agenda items:

Based on the meeting, the scope of the new subcommittee is “The formulation of test methods, specifications, definitions, recommended practices, and promotion of knowledge relating to the application and performance of precast concrete stormwater management products.”

The new subcommittee agreed that there are many existing ASTM specifications that can be readily referenced for a stormwater management product structure. However there is a lack of consensus and consequently a lack of standards that address the performance of the components inside the structure. As such, the subcommittee will be investigating the best means for creation of a new set of product standards and specifications that not only address the manufacture and structural requirements but also the stormwater treatment performance aspects.

The subcommittee is actively seeking members who can provide valuable input and represent the various stakeholders in the growing stormwater management industry. The next meeting will take place during the June 2007 ASTM International Committee Week in Norfolk, Va.

ASTM Committee C27 Approves New Specification for Sealing Pipes

New Standard Specification provides flexible sealing and eliminates infiltration and exfiltration from pipe entry.

By Mike R. Miller

Following two years of development, peer review and balloted revision, Subcommittee C27.30 has approved and published the first ASTM Standard written specifically to address the sealing requirements of pipe entry into on-site (septic) treatment systems. Designated C 1644-06, “Standard Specification for Resilient Connectors Between Reinforced Concrete On-Site Wastewater Tanks and Pipes,” the Standard Specification addresses the unique requirements for permanent, flexible, watertight sealing of pipe entry into on-site tanks, including:

1. Minimum material requirements for all components

2. Performance requirements demonstrating sealing at a minimum 5 psi hydrostatic pressure (11.5-foot head) against both infiltration and exfiltration in each of three conditions:

• Pipe in straight alignment
• Pipe with shear load of 50 pounds per inch diameter
• Pipe at angle of at least 7 degrees

3. Testing of each outside diameter and pipe type for which the connector is recommended

Engineers, specifiers, sanitarians and tank manufacturers can incorporate this new Standard Specification to upgrade their local requirements in keeping with the move toward improving watertightness of on-site systems.

Copies of the Standard Specification may be obtained from ASTM International, 100 Barr Harbor Drive, PO Box C700, West Conshohocken, PA 19428-2959, or call (610) 832-9585 or fax (610) 832-9555. Questions about the Standard Specification may be addressed to Mike R. Miller at (260) 348-9889.
