44、5.5 FlatteningThere shall be no evidence of splitting,cracking, or breaking by the specimens subjected to this testand performed in accordance with Test Method D2412. Flattenthree specimens of the pipe, 2 in. (50.8 mm) long, betweenparallel plates in a suitable press until the distance between thepl
45、ates is 40 % of the outside diameter of the pipe or the wallsof pipe touch. The rate of loading shall be uniform and suchthat the compression is completed within 2 to 5 min. Onremoval of the load, examine the specimens for evidence ofsplitting, cracking, or breaking.5.6 Impact ResistanceThe impact r
46、esistance for PVC pipeshall fall within the range specified by the 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 fla
47、t plate holderand 20-lb tup B for sizes 2 in. and less and 30-lb 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 flu
48、id bath ofwater and ethylene glycol at 32 to 35F (0 to 2C) for1horarefrigeratedair chamber at 32 to 35F (0 to 2C) for 4 h may be used if it can bedemonstrated that equivalent results are obtained. However, in cases ofdisagreement, the ice water mixture shall be used.5.7 Impact Quality AssuranceThe i
49、mpact quality assur-ance is a “GO/NOGO” test. Five specimens shall 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 second set shall fail. Ifnine out of the total ten specimens pass, the lot shall beconsidered to h
