ANNEX II 2. STACKING

Paragraphs 1. and 2. should read:

"1.

For conditions of international transport where the maximum vertical acceleration varies significantly from 1.8 g and when the container is reliably and effectively limited to such conditions of transport, the stacking load may be varied by the appropriate ratio of acceleration.

2.

On successful completion of this test the container may be rated for the allowable superimposed static stacking load which should be indicated on the Safety Approval Plate against the heading "Allowable stacking load for 1.8 g (kilogrammes and lbs)".

TEST LOADINGS AND APPLIED FORCES should read:

"TEST LOAD AND APPLIED FORCES

Internal load:

H

A uniformly distributed load such that the sum of mass of container and test load is equal to 1.8R. Tank containers may be tested in the tare condition.

Externally applied forces:

Such as to subject each of the four top corner fittings to a

vertical downward force equal to 1/4 x 1.8 x the gravitational force

of the allowable superimposed static stacking load."

ANNEX II 3. CONCENTRATED LOADS

TEST LOADINGS AND APPLIED FORCES should read:

"TEST LOAD AND APPLIED FORCES

(a) ON ROOF

Externally applied forces:

A concentrated gravitational force of load of 300 kg (660 lbs) uniformly distributed over an area of 600 mm x 300 mm (24 in x 12 in).

(b) ON FLOOR

Internal load:

Two concentrated loads each of 2,730 kg (6,000 lbs) and each added to the container floor within a contact area of 142 cm 12 (22 sq. in)",
