The 99 % lower confidence limit (LCL)shall be within 15 % of the average value. The LCL shall becalculated using the Students “t” distribution, with N-1 de

34、-grees of freedom, where N is the number of specimens. Thecritical t value shall be used to at least three significant digits.Alternatively, if the LCLexceeds the minimum PS requirementin Table 3, but is not within 15 % of the average, the samplemeets the requirements of the Pipe Stiffness testing.
