Updated C906-15 AWWA Standard To Publish Includes PE4710 State-Of-The-Art Resin

Working pressure rating WPR: The dimensional tolerances for diameter and wall thickness shall be the same tolerance on a percentage basis as that specified for the average wawa diameter and minimum wall thickness for the next smaller size. The product shall be made from only f906 materials listed within this standard.

Materials language has been added Sec. Materials shall comply with the requirements of the Safe Drinking Water Act and other federal requirements.

Occasional pressure surges Pos: Additionally, PPI collaborates with industry organizations that set standards for manufacturing practices and installation methods.

Two standards developed under the direction of NSF: This allowance assumes that the total number of surge events the piping will experience over its intended service life will not exceed one million. PPI is the premier technical, engineering and industry knowledge resource publishing data for use in development and design of plastic pipe systems. The fitting shall meet the five-second pressure test Sec. Exceptions to these requirements may only be made with the mutual consent of the manufacturer and the purchaser.

Like what you are reading? The aawa of solid-color nonblack or color-striped pipe is allowed. The test shall be performed at Minimum wall thicknesses in. The markings shall be applied in a manner that will not reduce the strength or otherwise damage the pipe. I agree to the Terms and Privacy Statement. Aww the effective strength of PE materials awwz on the duration of stress application and temperature, the effective safety factor when using a DF of 0. It is important that several specimens be tested to ensure that representative samples of the inside surface are tested.

Standard material code designation such as PE The test pressure of DR17 is also psi, which meets the specified test pressure. B Modification of Standard Pressure class such as PC This test shall be performed daily or at least once per production run, whichever is more frequent.

Molded fittings shall conform with the dimensional requirements described in the applicable ASTM fitting standard referenced in Section 2 when measured as specified in that standard. Description of fitting e.

Help Center Find new research papers in: Transient surge pressure depends on the instantaneous change in flow velocity. An engineer is designing a water system that operates at 85 psi and has some runs in it where the flow velocity is 4 fps. The maximum pressure increase and decrease that is anticipated in a system as the result of a sudden change in the velocity of the water. The surge pressure occurring in HDPE pipe is significantly lower than surge pressures occurring in cast or ductile iron pipe and is lower than that in PVC pipe of the same DR.

Some items in this standard are optional requiring identification of the selected option s such as material type, color, and size. The tensile strength shall be not less than 2, psi The second through fifth digits of the cell classification number given in Table 1 represent the minimum cell classification for the standard PE code designation listed.

The maximum total pressure allowed equals 1. Each qwwa shall be designed and manufactured to operate at not less than the design pressure of the pipe system for which it is intended. Each length of pipe shall be visually examined x906 checked for marking accuracy and legibility. A specimen taken from the midwall area of produc- tion pipe shall be tested for thermal stability in accordance with ASTM D Sec.

Joining methods shall be capable of conveying water at the design pressure of the piping system. Surge pressure is sometimes called water hammer. Use of This Standard. The maximum anticipated, sustained operating pressure applied to the pipe exclusive of transient pressures.

Subscribe I agree to the Terms and Privacy Statement. This test shall be run on samples from the pipe at least once per day. DR17 pipe is ok. Sufficient antioxidant must be added to ensure that production pipe meets the thermal stability requirements of Sec.

PPI AWWA C | C Statement

The sum of the maximum anticipated working pressure WP and the maximum anticipated recurring pressure surge PRS may be no greater than 1. Pipes are classified in accordance with standard pipe dimension ratios DRs i.

Remember me on this computer. The PE materials used to make pipe and fittings shall contain no ingredient in an amount that has been demonstrated to migrate into water in quantities that are considered to be detrimental awda the water quality.

For black product see Sec. Carbon-black levels shall be determined daily or for each production run of pipe, whichever is more frequent.
