gasket seating, and the
greater of the two values shall be used. For operating
conditions, the value of P shall be the design pressure, and
the values of S at the design temperature and W from
Formula (3) of 2-5(e) shall be used. For gasket seating, P
equals zero, and the values of S at atmospheric temperature
and W from Formula (4) of 2-5(e) shall be used.
