Fire Tests

We run an outstanding testing-laboratory in terms of fire tests especially fire tests on cables, wire ropes and lines.

Our laboratory offers an extensive range of fire tests on cables, cords and wires and is Notified Body for fire tests of cables and cords within the European Union’s Construction Products Regulation 305/2011/EU (CPR).

By means of a 3m cube, a fire table or a tube furnace we are able to provide fire tests on various plastics or other materials, not only on cables, cords and wires.

An essential component of the ets – Energie- und Telecom Service GmbH fire testing laboratory is our 3m cube, where smoke density measurements of cables burning under defined conditions are conducted. The cube has its name because this is a well-defined area with 3 x 3 x 3 meters per side.

The smoke production of a burning material is an important property regarding its fire behavior. Many plastics which are used in the cable technology are inherently strong smoke generators and its smoke production can only be reduced through addition of 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 also flame propagation analyses can be conducted.

The fire table of ets – Energie- und Telecom Service GmbH is positioned in a circulation-free area in order to carry out the following tests:

  • circuit integrity tests of electric cables under fire conditions
  • circuit integrity tests of optical fiber cables under fire conditions
  • fire integrity tests of electric cables, optional with water spray

Our accredited testing laboratory offers the possibility of heat release measurement and smoke production measurement on cables during flame spread test according to EN 50399. This new test method is the main fire test for cables and wires within the European Union’s Construction Products Regulation 305/2011/EU (CPR).

The new test device combining a test chamber with gas analyses instrumentation allows ETS to cover all fire tests included in the Construction Products Regulation for classification of cables into Euroclasses and for establishing ETS as Notified Body.

Our test laboratory is Notified Body for cables and cords according to the European Union’s Construction Products Regulation 305/2011/EU (CPR).

The Construction Products Regulation (CPR) is fully applicable in all EU countries since July 2013. Within this context the accredited testing laboratory ets – Energie- und Telecom Service GmbH is servicing our customers as One-Stop-Shop for achieving CE-labeling of our customer’s cable products.

By means of a tube furnace the following tests are performed at ets – Energie- und Telecom Service GmbH:

  • determination of halogen acid gas content
  • determination of acidity (by pH measurement) and conductivity
  • measurement of carbon black and/or mineral filler content in polyethylene compounds
