Incubation test FM 2 replicates on the three aged l0, 11 , 12 Liner and/or 5 - 574 and MI test sampled after incubation of MI Retained Value Crown' (ASTM D4238 195 days at 176 °F8 and shall be greater than 80 % at 190°C/2 . 16 Kg) applied stress of 250 psi and less than 120% . Note : FM = Florida Method of Test. 1 Required only when the resin used in the corrugation is different than that of the liner . A higher test temperature ( 194° F) may be used if supporting test data acceptable to the State Materials Engineer is submitted and approved in writing. Full test shall be performed on alternative pipe diameter of pipe based on wall profile design, raw material cell classification , and manufacturing process. Full test must be performed on maximum and minimum pipe diameters within a manufacturing rocess. Computer program to predict the 100 year SCR with 95 % lower confidence can be obtained from FDOT. 5 Single test for the junction and longitudinal profile may be used on alternating pipe sizes within a manufacturing process. Single point tests may not be used on maximum and minimum pipe sizes within a manufacturing process except by approval of he Engineer. Single point tests may be used for quality assurance testing purposes . Longitudinal profiles include vent holes and molded lines . 7 OIT and MI tests on the crown are required when resin used in the corrugation is different than that of the liner. 8 The incubation temperature and duration can also be 136 days at 185 °F. Within each replicate set of tests, the discrepancy range shall be within 6% . If an out -of range discrepancy occurs, repeat the three OIT tests. 10 The tests for incubated and "as-manufactured" pipe samples shall be performed by the same lab , same operator, the same esting device, and in the same day. 11 Within each replicate set of tests , the discrepancy range shall be within 9 %. If an out-of-range discrepancy occurs, repeat the o MI tests on the same pipe sample. If insufficient material is available, a repeat of one test is acceptable. 12 The MI retained value is detenn nuined using the average MI value of incubated sample divided by the average MI value of as - afactured pipe sample . Manufacturer may use ground class II, but not class I, pipe for reworked plastic . 948-2 .3 .3 Certification : Furnish to the Engineer certification from the manufacturer for each pipe diameter manufacturers LOT to be incorporated into the project that the pipe meets the requirements of these Specifications . Manufacturers seeking evaluation of a product in accordance with Departmental procedures must submit test reports conducted by a laboratory qualified by the Geosynthetic Accreditation Institute- Laboratory Accreditation Program (GAI- LAP) or qualified by ISO 17025 accreditation agency using personnel with actual experience running the test methods for class II HDPE pipe . Submit the test reports to the State Materials Office . - 220 - FPID ( S ) : 423186 - 1 - 58 - 01 t � �"�c� �i ; n a �`k� �:4 ,�+� �`�� 4� �.f f t c� t � '' F . s• „ ro _ x e r �,.', `r �� ".,.� � '<. aA . ,... , ,, 11 . .ti .. _ . „ k.�fi, r�.. 1 :;^', w.. .>,
