LPL

97,5 % lower bound value for an individual component failure, based on the long-term hydrostatic pressure or stress for a 20-year lifetime

Note 1 to entry: The LPL will always be lower than the LCL (3.2.71) for the nominal regression line (i.e. the prediction interval will always be larger than the confidence interval).
