3m Cube


An essential component of the ets - Energie- und Telecom Service GmbH laboratory is our 3m cube, where the flue gas density measurements are carried out. The cube is called 3m cube because this is a well-defined area with 3 x 3 x 3 meters per side. The smoke of a burning material is an important property in the fire behavior. Many plastics which are used in the cable technology are inherently strong smoke generators. You can reduce the smoke only with appropriate additives. The measurements of the smoke density of burning cables are carried out under practical conditions. The smoke density of various materials is determined by comparative tests.

The 3m cube also represents a circulation-free area, in which flame spread analyses can be accomplished.
