NOTE
1) API 620 Annex R.3.3 Design Allowable Stress (When, Full Containment and Outer Tank)
　The maximum allowable design tensile stress for the secondary liquid container may be higher,
　but shall not exceed the smaller of the following:
　- 150 % of the allowable tensile stress from Table 5-1 or Table Q-3 for the secondary liquid container material;
2) API 620 Annex Q.3.3.2 Design Allowable Stress (When, Full Containment and Outer Tank)
　The maximum allowable design tensile stress for the secondary liquid container may be higher,
　but shall not exceed the smaller of the following:
　- 150 % of the allowable tensile stress from Table Q-3 for the secondary liquid container material;
3) API 620 Annex R.6.2
　The hydrostatic test shall not produce a membrane tensile stress in any part of the tank exceeding 85%
　 of the minimum specified yield strength or 55% of the minimum specified tensile strength of the material.
　 Allowable Stress for Hydrostatic test : Stest = Min( 0.55 * Ft, 0.85 * Fy), For Carbon Steel
　 Allowable Stress for Hydrostatic test : Stest = Min( 0.55 * Ft, 0.90 * Fy), For A240 Stainless Steel
