45、e manufacturersdesignated Impact Classification Cell (IC). Table 4 lists impactclassification cell for SDR 17 and 21 pipe. The impactclassification rating for PVC pipe shall be determined inaccordance with Test Method D2444 using a flat plate holderand 20-lb tup B for sizes 2 in. and less and 30-lb
46、tup B for alllarger sizes. The specimens shall be conditioned in a mixture ofice and water at 32 to 35F (0 to 2C) for1h(Note 2) andtested immediately on removal from this medium.NOTE 2Other conditioning media such as a refrigerated fluid bath ofwater and ethylene glycol at 32 to 35F (0 to 2C) for1ho

However, in cases ofdisagreement, the ice water mixture shall be used.5.7 Impact Quality AssuranceThe impact quality assur-ance is a “GO/NOGO” test. Five specimens shal
48、l be impactedin accordance with Test Method D2444 using the tup andholder specified in 5.5 from a height determined by the lowervalue of the designated Impact Classification (IC) cell. All fivespecimens shall pass. If one specimen fails, a second set of fivespecimens shall be tested. None of the sec
49、ond set shall fail. Ifnine out of the total ten specimens pass, the lot shall beconsidered to have met the requirements of this test.NOTE 3This test is intended only for use as a quality control test, notfor use as a simulated service test.5.8 Extrusion QualityPVC pipe shall not flake or disin-tegrate when tested in accordance with the Test Method D2152.5.9 Outdoor Storage StabilityPVC pipe when stored out-doors unprotected for six months from the date of extrusionshall meet all the requiremen
