Posted November 26, This specification covers the design and performance of the rubber gasket joint only. Ptatohed, expect an answer 2. Work Item s – proposed revisions of aatm standard.

Infiltration or exfiltration quantities for an installed pipeline are dependent upon many factors other than the joints, and allowable quantities must be covered by other specifications and suitable testing of the installed pipeline and system.

Yeah, I wstm familiar with the standards’ just didnt know if anyone had ever spec’d on SWM facility outfalls. Link to Active This link will always route to the current Active version of the standard.

Note 1—This specification covers the design and performance of the rubber gasket joint only. I get into an argument with contractors on almost every project because they fail to read the plans and specifications. Sign In Sign Up.

The joint is made up of concrete surfaces, with a compression type rubber gasket.

Assembled joints should pass the f443 performance test without leakage at the joints: It seems to me that ASTM C might be more appropriate for storm drain pipe decent water-tightness, supports full pipe flow and ASTM C might be more appropriate for sewer pipe superior water-tightness, more suitable for partial-full gravity flow? Joints covered by ashm specification are normally adequate for hydrostatic pressures up to 13 psi 30 ft without leakage, when tested in accordance with Section 9.

The joint is made up of concrete surfaces with a groove on the spigot for an O-ring rubber gasket also referred to as a confined O-ring type joint. Posted December 19, This type of joint provides excellent inherent water tightness in both the straight and deflected position and meets all the joint requirements of ASTM C Active view current version of standard.

Joints covered by this specification are normally adequate for hydrostatic pressures up cc443 13 psi 30 ft without leakage, when tested in accordance with Section 9. Historical Version s – view previous versions of standard. Infiltration or exfiltration quantities for an installed pipeline are dependent upon many factors other than the joints, and allowable quantities must be covered by other specifications and suitable testing of the installed pipeline and system.

Always ast to “value engineer” something as small as the gaskets that are called for.
