1、,.-.Designation:D 2314-80(Reapproved 1984)4clti,Standard Methods of Testing HOMOGENEOUS BITUMINIZED FIBER PIPE This standard is issued under the fwed designation D 2314;the number immediately foliowing the designation indicates theyear of original adoption or,i n the case of revision,the year of las
2、t revision.A number in parentheses indicates the year of last reapproval.A superscript epsilon(e)indicates an editorial change since the last revision or reapproval.1.Scope 1.1 These methods cover the procedures for testing homogeneous bituminized fiber pipe.H o-mogeneous bituminized fiber pipe is d

12、dure 9.1 After 48-h immersion in water at 21 to 24C(70 to 75F),remove the sections,drain and wipe dry,and reweigh to the nearest O.1 g.NOTE ISpecimens,after this test,may be used within Y 2 h for the wet crushing strength test(Section 3 5).10.Calculation and Report 10.1 Calculate the gain in mass to
13、 the nearest 0.1%as a percentage of original mass.Report the results separately for each specimen.11.Precision 1 1.1 Use the following criteria for judging the acceptability of results(95%probability)on samples from the same lot,from the same man-ufacturer,and of uniform wall thickness,f5%.I I.1.1 R
