Bureau International des Containers

Represented were France, Belgium, the Netherlands, Germany, Switzerland, Great Britain, Italy, and Sweden; with USA observers.

The International Union of Railways, UIC,[7] then standardised a container system for Western Europe called 'Porteur-aménagé', or "Pa-Behälter" / "Pa-containers" (UIC 590), based on the Netherlands' systems of waste disposal containers and 'Laadkisten' ("loading crates") for consumer goods.

Its system was adopted in Denmark, Belgium, the Netherlands, Luxembourg, West Germany, Switzerland and Sweden.

Once the larger containers of the ISO-design were gradually popularized, the "Pa-Behälter" system was supplanted, and withdrawn from use by the railways.

The Bureau International des Containers (BIC) was elected by the International Standardization Organization (ISO) in the late 1960s as the single registrar office in charge of the registration and protection of the container's owners and operator's identification code.

'Behältertragwagen' ("BT / container flatcar") predecessor to the ISO-type, with four mobile containers, including one open-top 'Von Haus zu Haus' ("Door-to-door") type.
