6.2.106.2.1 General This clause defines a method for the assessment of other means for closing and sealing in automatic shut-off valves. By this clause the term “class of control function A, B or C” is not related to the sealing force classes but to the class of control function as described in 4.3. Sealing force of valves shall be classified according to 4.1. The basic risks of fire and explosion in a gas appliance as a result of uncontrolled gas flow requires a control function class C system for the gas shut-off function. This is based on a comparison, made between automatic burner controller and gas shut-off function, the class of control function of each of them being considered equal. Although this European Standard is not based on a fault assessment approach as specified in EN 13611:2007, 6.6, the combination of two automatic shut-off valves is considered equal to a control function class C. This assumption is based on the construction and performance requirements of this European Standard. SIST EN 161:2011
