ANNEX
AMENDMENTS TO THE INTERNATIONAL CONVENTION FOR SAFE CONTAINERS (CSC), 1972
1. Paragraphs 14 to 16 of Article II (Definitions) are amended to read:
"14. "Maximum Operating Gross Mass" or "Rating" or "R" means the maximum allowable sum of the mass of the container and its cargo. The letter "R" is expressed in units of mass. Where the Annexes are based on gravitational forces derived from this value, that force, which is an inertial force, is indicated as "Rg".
15. "Tare" means the mass of the empty container including permanently affixed ancillary equipment.
16. "Maximum Permissible Payload" or "P" means the difference between maximum operating gross mass or rating and tare. The letter "P" is expressed in units of mass. Where the Annexes are based on the gravitational forces derived from this value, that force, which is an inertial force, is indicated as "Pg"."
New paragraphs 17 to 19 are added as follows:
"17. The word "load", when used to describe a physical quantity to which units may be ascribed, signifies mass.
18. The word "loading", for example, as in "internal loading", signifies force.
19. The letter "g" means the standard acceleration of gravity, "g" equals 9.8 m/s2 ."
2. Annex I, subparagraph 1(b) of regulation 1 is amended to read:
"(b) On each container all maximum gross mass markings shall be consistent with the maximum gross mass information on the Safety Approval Plate."

|
|
Internal load: |
(ii) |
Lifting from grappler arm positions: |
|
|
|
A uniformly distributed load such that the sum of the mass of container and test load is equal to 1.25R. In the case of a tank-container, when the test load of the internal load plus the tare is less than 1.25R, a supplementary load distributed over the length of the tank is to be added to the container. |
