Germany closes standardisation gap for SHEV controllers

D+H smoke vent control panels already ISO 21927-9 certified by VdS

The German Institute for Standardisation (DIN) has played a lead role in the enhancement of an important part of a DIN standard relating to smoke and heat exhaust ventilation. The recently published draft version of DIN 18232-9 refers to the internationally relevant ISO 21927-9 standard. As a result, an EN standardisation gap that existed throughout Europe has finally been closed in Germany. In addition to the specifications for natural smoke and heat exhaust ventilators (NSHEV) and power supplies, the minimum requirements for control panels are now also clearly defined. D+H control panels for smoke and heat exhaust ventilation (SHEV) already fulfil these minimum guidelines and are certified by the Verband der Sachversicherer (VdS) (English: German Association of Insurers) in accordance with ISO 21927-9 guidelines.

ISO 21927-9, which was published in 2012, regulates the testing of control panels and power supply systems. The draft version of DIN 18232-9, now published in Germany with reference to ISO 21927-9, stipulates clear minimum requirements for the testing of control panels in Germany. These requirements cover aspects such as operating safety, environmental classification and the housing colour of the smoke vent buttons.

Smoke vent control panels from D+H already fulfil the minimum re-quirements that have been added in the draft of the new DIN standard. Accordingly, SHEV control panels from D+H have already been certified by the technical inspection body of VdS in accordance with the requirements of ISO 21927-9.
