IMDG CODE UN PACKING CODE

IMDG CODE UN PACKING CODE

The United Nations Committee of Experts on the Transportation of Dangerous Goods has

established a uniform international system for identifying and packaging Class 3, 4, 5, 6.1, 8

and 9 dangerous goods for transport. The UN requirements are found in standard

CAN/CGSB 43.150-97 “Performance Packaging for the Transportation of Dangerous Goods”.

Here’s a summary:

How the UN Packaging System Works

The UN Committee has assigned all dangerous goods to one of three Packing Groups:

Packing Group I (high danger), II (medium danger) and III (low danger). The list of dangerous

goods and the Packing Group for each can be found in the ICAO Technical Instructions, the

IMDG Code or the TDG Regulations. The Committee has also developed what is referred to

as ‘UN packaging’. UN packagings have been performance tested for their resistance to drop,

stacking and internal pressure, the verity of the test varying with the Packing Group. Each

packaging is marked with a code that indicates the type of packaging, Packing Group, form

(liquid or solid), relative density, inner packagings, etc. for which the packaging was tested by

the manufacturer and can, therefore, be ud.

It is the shipper’s responsibility to lect the appropriate packaging for dangerous goods.

Shippers should become familiar with the code ud in the UN package mark. To lect a UN

packaging that is suitable for their product, they need the following information:

• the Packing Group for their product,

• the compatability of their product with the packaging material,

• the vapour pressure at 55C or 50C and the relative density (liquids),

• the net mass (solids).

The UN Package Mark

Here’s a typical UN package mark,

UN1A1/Y1.8/100/95/CAN/ABC2-0011.1/0.8/1.1

24567891013

1. UN Symbol

2. Packaging Code:

1 – drumA – steel1 – Non-removable head

2 – wooden barrelB – aluminum2 – Removable head

3 – jerricanC – natural wood

4 – boxD – plywood

5 – bagF – reconstituted wood

6 – composite G – fiberboard

packaging

H – plastic

L – textile

M – paper

N – metal (other than

steel or aluminum)

P – glass, porcelain or

stoneware

3. Packing Group:

X – acceptable for Packing Groups I, II and III substances

Y – acceptable for Packing Groups II and III substances only

Z – acceptable for Packing Group III substances only

4. The relative density (liquids. If the relative density isn’t marked, it is considered to be 1.2) or

the gross mass in kg (solids) for which the packaging was tested.

5. The hydrostatic test pressure in kPa (liquids) or the letter ‘S’ meaning the package was

tested for solids or inner packagings.

6. Year of manufacture.

7. Country code for the country authorizing the allocation of the mark.

8. Name or registered symbol of the manufacturer.

9. Transport Canada design registration number.

10. Nominal thickness of the material of construction (metal drums only); top

head/body/bottom head

Selectin广州高考分数线 g the Right UN Packaging for the Product

1. Single Packagings. Single packagings are constructed of a single component (e.g., steel

drums).

When ordering packaging from a supplier, specify a UN single packaging

• permitted for the product by Part II of standard CAN/CGSB 43.150-97

• with a marked Packing Group at or above that for the product;

• in which the material in contact with the product is compatible with and impermeable

• with a marked relative density at or above that for the product (liquids);

• with a marked test pressure suitable for the product (liquids):

Test Pressure

• with a marked gross mass that is adequate for the product (solids);

• with a nominal thickness 1.1/0.8/1.1 (top head/body/bottom head) or greater if it’s a

steel drum over 150 litres capacity and to be reud in Canada for dangerous goods.

There are also requirements for reconditioning some steel drums reud for liquid

transport, e ction 18 of standard CAN/ings may be ud

for products having a form or Packing Group different from that in the marking, within

the following limits:

- PG I 中国军衔等级 packagings for liquids may be ud for PG II liquids with a relative density

not exceeding the greater of 1.8 or [1.5 X the marked relative density]*;

- PG I packagings for liquids may be ud for PG III liquids with a relative density

not exceeding the greater of 2.7 or [机器人翻译 2.25 X the marked relative density]*;

- PG II packagings for liquids may be ud for PG III liquids with a relative density

not exceeding the greater of 1.8 or [1.5 X the marked relative density]*;

- A packaging for liquids may be ud for solid products if the gross mass (kg)

doesn’t exceed the packaging’s capacity (litres) X the marked relative density;

- PG I packagings for liquids may be ud for PG II solid products if the gross

mass (kg) doesn’t exceed the packaging’s capacity (litres) X 1.5 X the marked relative

density*;

- PG I packagin网络断断续续 gs for liquids may be ud for PG III solid products if the gross

mass (kg) does形容大雨的成语 n’t exceed the packaging’s capacity (litres) X 2.25 X the marked

relative density*;

- PG II packagings for liquids may be ud for PG III solid products if the gross

mass (kg) doesn’t exceed the packaging’s capacity (litres) X 1.5 X the marked relative

density*;

*packagings should be capable of withstanding a 3m 丘的成语 high stacking load at the higher

relative density

2. Combination Packagings. Containers having inner packagings are called

‘combination packagings’ (e.g., fibreboard box containing bottles):

When ordering packaging from a supplier, specify a UN combination packaging

•

o permitted for the product by Part II of standard CAN/CGSB 43.150-97

o with a marked Packing Group at or above that for the product;

o in which the material in contact with the product is compatible with and

impermeable to the product;

o with a marked gross mass that is adequate for the小孩能吃羊肉吗 product and packaging;

o that has been tested with the inner packagings to be ud for the product;

A packaging may be ud to contain inner packagings that differ from tho that were

ud in the tests, within the following limits:

- A lesr number of inner packagings may be shipped in the box if voids are filled and

cushioning is maintained.

- If a box was tested with veral different types of inner packagings, inners from each

design may be shipped together in the box.

- Inner packagings that are similar in design to the inners that were tested with the box

(shape, same or smaller openings, similar type of closure, equivalent or smaller size,

equivalent or better materials) may be shipped in the box.
