-I . ...., ., polyethylene. Use only concrete or metal mitered end sections as indicated in the Design Standards. When rubber gaskets are to be installed in the pipe joint, the gasket shall be the sole element relied on to maintain a tight joint. Test pipe joints at the plant hydrostatically using test methods in ASTM D 3212 [ASTM D 3212M]. Soil tight joints must be watertight to 2 psi [13.8 kPa]. Watertight joints must be watertight to 5 psi [34.5 kPa] unless a higher pressure rating is required in the plans. Provide certification of the actual mean diameter of pipe shipped to the project. Include in the certification the minimum and maximum diameters used to certify the actual mean diameter. The certification shall be attested to by a person having legal authority to bind the manufacturing company. Obtain pipe products from producers listed on the Department's List of Qualified Flexible Pipe Manufacturing Plants, which may be viewed at the following: http://www.dot.state.fl.us/statematerialsoffice/qu ality /programs/q ualitycontrol/materialslisti ngs/sources/drainagesource.pdf . Ensure that each shipment of products to the job site includes a list of products and each product has an affixed legible stamp mark of the plant, indicating its compliance with the requirements of the plant's Department approved Quality Control Plan and Contract Documents. Accept responsibility of either obtaining products from another approved plant, or await re-approval of the plant, when the plant is removed from the Department's list of Flexible Pipe Manufacturing Plants. The Engineer will not allow changes in Contract Time or completion dates as a result of the plant's loss of qualification. Accept responsibility for all delay costs or other costs associated with the loss of plant's qualification. 948-2.3.2 Additional Requirements for Class II Polyethylene Pipe: Meet the following requirements: . . ..., . ..., . ..., . ..., . ,.., . , . .., . .., ., Table 1 Stress Crack Resistance of Pipes Pipe Location T est Method Test Conditions Requirement 10% Igepal solution at 500C Average failure time of the Pipe Liner FM 5-572, and 600 psi applied stress 5 pipe liner shall be ~ 17 Procedure A replicates hours, no single value shall be less than 12 hours..
