16 Stacking test (annex II, paragraph 2)

  16.1 The following can be used as guidance in interpreting paragraphs 1 and 2 of the stacking test:

  For a 6-high stacking of 20-ton (20,320 kg/44,800 lb) containers the mass on the bottom container would be 5 x 20 tons (20,320 kg/ 44,800 lb), i.e. 100 tons (101,600 kg/224,000 lb). Thus, in the case of a 20-ton container with 6-high stacking capability the plate should indicate: ALLOWABLE STACKING MASS FOR 1.8g: 101,600 kg/ 224,000 lb.

  16.2 The following may be useful guidance for determining allowable stacking mass:

  The allowable stacking mass for 1.8g may be calculated by assuming a unifonn stack loading on the cornerpost. The stacking test load applied to one corner of the container shall be multiplied by the factor and the result expressed in appropriate units.

  16.3 The following is a useful example of how the allowable stacking mass could be varied, as prescribed in paragraph 1 of the stacking test:

  If on a particular journey the maximum vertical acceleration on a container can be reliably and effectively limited to 1.2g, the allowable stacking mass permitted for that journey would be the allowable stacking mass stamped on the plate multiplied by the ratio of l.8 to 1.2 (i.e. allowable stacking mass on the plate x = stacking mass permitted for the journey).
