The stacking load shall be calculated according to formula (1): PK×H_h×M×9.8
Wherein:
P is the stacking load applied to the container, in Newton (N); H is the stacking height, in meters (m);
I is the height of a single steel drum, in meters (m);
M is the mass of a single steel drum after it is filled with the corresponding articles, in kilograms (kg); K is the coefficient of variation.
: The stacking height for domestic transportation is 3 m, and for sea transportation is 8 m. 7.5 Drop test
Perform according to the provisions of GB/T4857.5. The drop height is shown in Table 2 and Table 3, and the following conditions are met: (1)
a) Fill a small-opening steel drum with 98% water and drop it at the weakest part of the steel drum edge. The drop should be drilled at the highest part of the steel drum; b) Fill a medium-opening and full-opening steel drum with 95% sand and shavings mixture with a density of 1.2 g/cm3 and drop it at the weakest part of the steel drum edge.
7.6 Sealing device assembly quality inspection
Perform according to the provisions of GB/T1325.
