The generic requirements for controls are given in EN 13611:2015 and methods for classification and

assessment for new controls and control functions are given in prEN 14459:2014, Clauses 1 up to and

including 7.13 (see Figure 1).

The requirements for controls are given in the specific control standard (see Figure 1).

Multifunctional Controls (MFC) according to EN 126:2012 with two or more controls and Application Control

Functions, e.g. the Gas Shut-off Control Function, being inherently multifunctional controls. Each control

integrated in the MFC meets the applicable requirements of the relevant control standard(s). In addition,

EN 126:2012 covers requirements for the safety related interactions between the different devices.
