MEMPHIS AREA ENGINEERING AND SCIENCES CONFERENCE
Christian Brothers University has offered a Packaging Engineering Certificate since the 2002-2003 academic
year. The program covers the basics of packaging engineering, including materials, distribution
packaging, and medical packaging.
This presentation will give the history of transport packaging and It will describe the essence of the
International Convention for Safe Containers (CSC).
A CONTAINER is a shipping equipment element which is:
• Used repeatedly, so it should be resistant enough to allow its continue use.
• Specially built to make merchandise’s shipping easier by one or more ways of transportation, without handling the merchandise internally.
• Built in a way that it can be carried or handled easily.
HISTORY
Transport packaging emerged in the 1880s as the industrial revolution
blossomed and manufactures began shipping their goods nationwide via railroad.
Containers were usuallymade of wood, textiles,or glass.
From the end of World War I to the end of World War II, the use ratio of corrugated to wood containers went from 20/80 to 80/20. Pallets become popular for industrial use following World War II, and unitizing of high volume products for shipment accelerated in the 1950s.
After the 50’s the use of cargo containers to send merchandise by sea increased as well as the construction of specialized cargo ships. This increased the interest to improved the security in the transportation of such containers.
The conventions are applied to maintain the safeness of the human lives involve in the Handling and Transportation of CONTAINERS.

In London, England, on December 2 of
1972 was celebrated the International Convention for Safe Containers, CSC
Signed by:
the members of the International Maritime
Organization, IMO.
CSC 1972
The convention will be applied to maintain the safety of the people involved in the handling and transportation of containers.
Also this applies to new and used containers in international transportation, with the exception of the containers built exclusively for air transportation.
In this convention were defined all the constructive, operative, security, inspection and control aspects of the containers subject to this convention.

Annex II :Annex II : Structural safety requirements and Structural safety requirements and teststests
Annex II : Structural safety requirements and tests
“…In all phases of the operation of containers, the forces as a result of motion, location, stacking and gravitational effect of the loaded container and external forces will not exceed the design strength of the container.”
CONSTRUCTION
1. A container made from any suitable material which satisfactorily performs the following test without sustaining any permanent deformation or abnormality which would render it incapable of being used for its designed purpose shall be considered safe.
2. The dimensions, positioning and associated tolerances of corner fittings shall be checked having regard to the lifting and securing systems in which they will function.
Annex II : Structural safety requirements and tests
Test loads and test procedures:
1. Lifting
2. Stacking
3. Concentrated Loads
4. Transverse Racking
5. Longitudinal Restraint 6. End – Walls
7. Side - Walls
Structural safety requirements and tests1. Lifting
The container, having the prescribed internal loading (2R), shall be lifted in such a way that no significant acceleration forces are applied. Also the container shall be suspended or supported for five minutes and then lowered to the ground.
i) Lifting from top corner fittings
L > 10 ft shall have lifting forces applied vertically at all four top corner fittings.
L =< 10 ft in such a way that the angle between each lifting device and the vertical shall be 30º.
ii) Lifting from bottom corner fittings Lifting forces applied in such a manner that the lifting devices bear on the bottom
corner fittings only; the lifting forces shall be applied at angles to the horizontal of:
L => 40 ft angle = 30º L => 30 ft angle = 37º L => 20 ft angle = 45º L < 20 ft angle = 60º
2. Stacking
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 1.8g (kg and lbs).
Internal Load: A uniformly distributed load such that the sum of the mass of container and test load is equal to 1.8R.
External Load: Such as to subject each of the four top corner fittings to a vertical downward force equal to 0.25 x 1.8 x the
gravitational force of the allowable superimposed static stacking load
Structural safety requirements and tests
3. Concentrated Loads
i) On roofinternal load = None.
external load = A concentrated gravitational force of 300 kg (660 lb) uniformly distributed over an area of 600
mm x 300 mm (24 in x 12 in).
ii) On floorinternal load = Two concentrated loads, q = 2730 kg (6000lb), each
applied to the container floor on a contact area of 142 cm (22 sq in)
external load = None.
The container shall be tested for a contact area 22 sq in on each surface, the surface width being 180 mm (7in) spaced 760 mm (30 in) apart, center to center, should be maneuvered over the entire area of the container.
Structural safety requirements and tests
5. Longitudinal Restraint (Static Test)
Containers when carried by inland modes of transport, may sustain accelerations of 2g applied horizontally in a longitudinal direction
Internal load = R.
External load = Longitudinal compressive and tensile forces of magnitude Rg, that is, a combined force
of 2Rg on the base of the container as a whole.

6. End – Walls
These should be capable of withstanding a force of not less than 0.4 times the force equal to gravitational force by maximum permissible payload (0.4Pg)
7. Side – Walls
These should be capable of withstanding a force of not less than 0.6 times the force equal to gravitational force by maximum permissible payload. (0.6Pg).
Open topped containers shall be tested in the condition in which they are designed to be operated, for example, with removable top members in position.
In case of a strength factor different from the one indicated above for the End Walls
and the Side Walls, this factor shall be indicated on the Safety Approval
Plate in accordance with annex I, regulation 1.
Annex I, Regulation 1 Safety Approval Plate
The Safety Approval Plate plate shall take theform of a permanent, non-corrosive, fireproofrectangular plate measuring not less than
200mmx 100mm
