Substance information(collapsed)

The BAM name is based on the "name and description" from the regulations and the IUPAC rules, but may be supplemented with further information so that significant differences between two dangerous goods data sets are apparent.

Remark (german): Abweichend von den Vorschriften des IMDG-Codes, der ICAO TI und der UN-Modellvorschriften wird bei dieser UN-Nummer in Tabelle A des ADR/RID/ADN zusätzlich die Nebengefahr der Klasse 3 angegeben. Eine Nachfrage bei der PTB nach dem Flammpunkt ergab, dass HCN-haltige Gemische definitiv entzündbare Dämpfe entwickeln. Zur Bewertung des Ausmaßes sind jedoch Messungen erforderlich. Stoffe, die neben entzündbaren auch hochtoxische Gase und Dämpfe abgeben, können von der PTB nicht auf ihren Flammpunkt vermessen werden. Aufgrund der fehlenden Information zum Flammpunkt wurde die Überlegung des BMDV, einen Antrag bei UN (TDG) für das Einfügen der Nebengefahr der Klasse 3 zu stellen, erst einmal zurückgestellt.

Mixed packing(collapsed)

According to Table A, Chapter 3.2 of ADR/RID, the following encodings apply:

Encodings

Section 4.1.10 applies:

4.1.10 Special provisions for mixed packing

4.1.10.1 When mixed packing is permitted in accordance with the provisions of this section, different dangerous goods or dangerous goods and other goods may be packed together in combination packagings conforming to 6.1.4.21, provided that they do not react dangerously with one another and that all other relevant provisions of this Chapter are complied with.

NOTE 1: See also 4.1.1.5 and 4.1.1.6.
NOTE 2: For radioactive material, see 4.1.9.

4.1.10.2 Except for packages containing Class 1 goods only or Class 7 goods only, if wooden or fibreboard boxes are used as outer packagings, a package containing different goods packed together shall not weigh more than 100 kg.

4.1.10.3 Unless otherwise prescribed by a special provision applicable according to 4.1.10.4, dangerous goods of the same class and the same classification code may be packed together.

See also subsections 4.1.1.5 and 4.1.1.6, section 5.1.4 and subsection 6.1.4.21:

4.1.1.5 Inner packagings shall be packed in an outer packaging in such a way that, under normal conditions of carriage, they cannot break, be punctured or leak their contents into the outer packaging. Inner packagings containing liquids shall be packed with their closures upward and placed within outer packagings consistent with the orientation marks prescribed in 5.2.1.10. Inner packagings that are liable to break or be punctured easily, such as those made of glass, porcelain or stoneware or of certain plastics materials, etc., shall be secured in outer packagings with suitable cushioning material. Any leakage of the contents shall not substantially impair the protective properties of the cushioning material or of the outer packaging.

4.1.1.5.1 Where an outer packaging of a combination packaging or a large packaging has been successfully tested with different types of inner packagings, a variety of such different inner packagings may also be assembled in this outer packaging or large packaging. In addition, provided an equivalent level of performance is maintained, the following variations in inner packagings are allowed without further testing of the package:

  1. Inner packagings of equivalent or smaller size may be used provided:
    1. the inner packagings are of similar design to the tested inner packagings (e.g. shape – round, rectangular, etc.);
    2. the material of construction of the inner packagings (glass, plastics, metal, etc.) offers resistance to impact and stacking forces equal to or greater than that of the originally tested inner packaging;
    3. the inner packagings have the same or smaller openings and the closure is of similar design (e.g. screw cap, friction lid, etc.);
    4. sufficient additional cushioning material is used to take up void spaces and to prevent significant movement of the inner packagings; and
    5. inner packagings are oriented within the outer packaging in the same manner as in the tested package.
  2. A lesser number of the tested inner packagings, or of the alternative types of inner packagings identified in (a) above, may be used provided sufficient cushioning is added to fill the void space(s) and to prevent significant movement of the inner packagings.

4.1.1.6 Dangerous goods shall not be packed together in the same outer packaging or in large packagings, with dangerous or other goods if they react dangerously with each other and cause:

  1. combustion or evolution of considerable heat;
  2. evolution of flammable, asphyxiant, oxidizing or toxic gases;
  3. the formation of corrosive substances; or
  4. the formation of unstable substances.

[...]

5.1.4 Mixed packing

When two or more dangerous goods are packed within the same outer packaging, the package shall be labelled and marked as required for each substance or article. If the same label is required for different goods, it only needs to be applied once.

6.1.4.21 Combination packagings

The relevant requirements of section 6.1.4 for the outer packagings to be used, are applicable.

NOTE: For the inner and outer packagings to be used, see the relevant packing instructions in Chapter 4.1.
