Questions concerning the UN quality labels and necessary packaging

If you have questions about the UN quality labels and the necessary packaging, feel free to contact us.

CAUTION: when we give you advice concerning the necessary UN quality labels and packaging, then this always has to be checked by the person who fills up the packaging. It is this person who is responsible for the filled packaging.

UN quality labels for barrels, buckets, canisters, jerry cans,...

UN symbol or the letters "UN"
1A2 = type of packaging (e.g. 1A1 = metal drum, 1H2 = PE lid barrel
1 = barrel (e.g. 3 stands for jerry can)
A = steel (e.g. H stands for synthetic material, G stands for carton)
2 = with removable lid (e.g. 1 stands for drum)
Marking in 2 parts
1st part
- e.g. X = packaging group (see further X, Y or Z)
2nd part
- e.g. 1.8. for fluids: density of the material that was used to test the construction type (if 1.2., this can be omitted).
- Or e.g. 220 for solids with a maximum gross weight in Kg (e.g. 220Kg)
250 or S:
- for fluids: maximum hydraulic proof
- The letter S for solids
06 = last 2 digits of year of manufacture
B = abbreviation of the country that approves of the feature
.... = name of the manufacturer and reference numbers of the certificate of approval
e.g. UN/1A2/X1.2/250/06/B/... or UN/X220/S/06/B/...

UN quality labels for IBC's

UN symbol or the letters "UN"

(6) = fabrication number
e.g. UN31HA1/Y/(1)/F/(2)/BVT/102618/7089/1968/68/1020/(3)/(4)/(5)/100/(6)

Packaging groups (chapter 2 of ADR)

For each class of danger, there is a classification of 3 packaging groups. For most of our packaging only class 3 (combustible fluids), class 6 (toxic fluids) and class 8 (corrosive materials) are relevant.

a) Combustible fluids
Materials and objects in class 3 are listed in chart A of chapter 3.2. The materials that are not named in chart A of chapter 3.2. have to be assigned to the right section of 2.2.3.3. and to the right packaging group, according to the guidelines. In relation to their class of danger during transportation, the fluids in level 3 must be assigned to one of the following packaging groups:
i) Packaging group I very dangerous materials: combustible fluids with a boiling point or start of cooking process of at most 35 degrees C, and combustible fluids with an ignition point lower than 23 degrees C and which are very toxic according to the criteria of 2.2.61.1. or very corrosive according to the criteria of 2.2.8.1;
ii) Packaging group II dangerous materials: combustible fluids with an ignition point lower than 23 degrees C, which have not been assigned to packaging group I, except the materials of 2.2.3.1.4.;
Packaging group III materials with low level of danger: combustible fluids with an ignition point of 23 to 61 degrees C (limiting value included), and the materials of 2.2.3.1.4.

b) Toxic materials
2.2.61.1.4 Depending on the extent to which they are dangerous for transportation, the materials of class 6.1. have to be classified in these three packaging groups:
i) packaging group I: very toxic materials
ii) packaging group II: toxic materials
iii) packaging group III: materials with low level of toxicity

c) Corrosive materials
2.2.61.1.4. Depending on the extent to which they are dangerous for transportation, the materials of class 6.1. have to be classified in these three packaging groups:
i) packaging group I: very corrosive materials
ii) packaging group II: corrosive materials
iii) packaging group III: low-corrosive materials

Packaging with label X is suitable for packaging groups I, II and III.
Packaging with label Y is suitable for packaging groups II and III.
Packaging with label Z is suitable for packaging group III.

Regulation of the drop height (chapter 6)

6.1.5.3.4. Drop height

a) For solids and fluids, if the test is executed with the solids or fluids that have to be transported or with other material, which in essence has the same physical features.

Packaging group I: drop height 1.8m
Packaging group II: drop height 1.2m
Packaging group III: drop height 0.8m

b) For fluids, if the tests are executed with water:
i) when the density of the product that has to be transported is no more than 1.2:

Packaging group I: drop height 1.8m
Packaging group II: drop height 1.2m
Packaging group III: drop height 0.8m

ii) when the density of the product that has to be transported is no more than 1.2:
the calculation of the drop height is based upon the density of the materials which have to be transported (round up to one decimal):

Packaging group I: drop height in m: density x 1.5
Packaging group II: drop height in m: density x 1.0
Packaging group III: drop height in m: density x 0.6

Determination of hydraulic testing pressure (chapters 4 and 6)

a) 4.1.1.10 Fluids may only be loaded into packaging (including IBC's) which has enough resistance to the internal pressure which can occur in normal transportation circumstances.
Packaging and IBC's which respectively have 6.1.3.1 d) and 6.5.2.2.1. prescribed as the hydraulic testing pressure regulation, may only be filled with fluids of which the vapour pressure:
i) either causes, at a temperature of 55 degrees C, a total manometric pressure in the packaging or the ICB's (vapour pressure of the product + partial pressure of the air and other inert gases - 100 kPa), determined based upon the maximum filling as prescribed in section 4.1.4.4. and a filling temperature of 15 degrees C is no more than 2/3 of the aforementioned testing pressure;
ii) either, at a temperature of 50 degrees C, lower than 4/7 of the sum of the aforementioned testing pressure and 100 kPa;
iii) either, at a temperature of 55 degrees C, lower than 2/3 of the sum of the aforementioned testing pressure and 100 kPa.

b) 6.1.5.5.4. Testing method and testing pressure which has to be applied
Hydraulic pressure (manometerpressure), as regulated according to one of the following methods, must be:
i) at least equal to the total manometric pressure in the packaging (= the vapour pressure of the material + the partial pressure of air and other inert gases - 100 kPa) at a temperature of 5 degrees C, multiplied by a safety coefficient of 1,5. In determining this total manometric pressure, the maximum filling degree is assumed (as mentioned in 4.1.1.4.) and a filling temperature of 15 degrees C; or
ii) at least equal to the vapour pressure of the material which has to be transported at a temperature of 50 degrees C x 1,75 - 100kPa; however this must at least be 100 kPa; or
iii) at least equal to the vapour pressure of the material which has to be transported at a temperature of 55 degrees C x 1,5 - 100 kPa; however this must at least be 100 kPa

c) 6.1.5.5.5. The packaging that is used for products from packaging group I during 5 or 30 minutes, depending on the construction material of of the packaging, must be tested with a testing pressure if at least 250 kPa (manometric pressure).
