  4.2.1.2 The design vapour pressure P o as defined in 4.2.6 should not normally exceed 0.25 bar. If, however, the hull scantlings are increased accordingly, P o may be increased to a higher value but less than 0.7 bar.

  4.2.1.3 Integral tanks may be used for products provided the boiling point of the cargo is not below -10°C. A lower temperature may be accepted by the Administration subject to special consideration.
