  6.1 Accident design condition as described in section 4.18.3 of this Code shall be complied with as applicable, depending on the cargo containment system concept.

  6.2 Load and resistance factors may be relaxed compared to the ultimate limit state considering that damages and deformations can be accepted as long as this does not escalate the accident scenario.

  6.5 Resistance factor γR shall in general be taken as 1.0.

  6.6 Consequence class factors γC shall in general be taken as defined in paragraph 4.4 of this standard, but may be relaxed considering the nature of the accident scenario.

  6.7 The characteristic resistance Rk shall in general be taken as for the ultimate limit state, but may be relaxed considering the nature of the accident scenario.

  6.8 Additional relevant accident scenarios shall be determined based on a risk analysis.
