What is BS EN 13611 - Safety and control devices for burners and appliances burning gaseous and/or liquid fuels about?
BS EN 13611 discusses safety and control devices for burners and appliances. Safety and control devices are used to directly start and stop dangerous machine movements. BS EN 13611 specifies the general safety, design, construction, and performance requirements and testing of safety, control or regulating devices (hereafter referred to as controls) for burners and appliances burning one or more gaseous fuels or liquid fuels. BS EN 13611 is applicable to controls with declared maximum inlet pressure up to and including 500 kPa and of nominal connection sizes up to and including DN 250.
BS EN 13611 specifies general product requirements for the following controls:
- Automatic shut-off valves
- Automatic burner control systems
- Flame supervision devices
- Gas/air ratio controls
- Pressure regulators
- Manual taps
- Mechanical thermostats
- Multifunctional controls
- Pressure sensing devices
- Valve proving systems
- Automatic vent valves
BS EN 13611 applies for control functions that are not covered by a specific control standard for burners and appliances burning one or more gaseous fuels or liquid fuels. BS EN 13611 applies also for safety accessories and pressure accessories with a product of the maximum allowable pressure PS and the volume V of less than 600 000 kPa · dm3 (6 000 bar · L) or with a product of PS and DN of less than 300 000 kPa (3 000 bar).
Who is BS EN 13611 - Safety and control devices for burners and appliances burning gaseous and/or liquid fuels for?
BS EN 13611 on safety and control devices is useful for:
- Burner manufacturers
- Valve manufacturers
- Gas cylinder manufacturers
- Design engineer
- Quality control personnel
- Research and development facilities
Why should you use BS EN 13611 - Safety and control devices for burners and appliances burning gaseous and/or liquid fuels?
Safety and control devices for burners and appliances are designed to help protect workers against health or safety risks on the job site. BS EN 13611 recognizes the safety level specified by CEN/TC 58 and is regarded as a horizontal standard dealing with the safety, construction and performance of controls for burners and appliances burning gaseous and/or liquid fuels and to their testing. The general requirements for controls are given in BS EN 13611 and methods for classification and assessment for new controls and control functions are given in EN 14459:2015. BS EN 13611 specifies multifunctional controls combining two or more controls and application control functions, one of which is a mechanical control function. The requirements for controls and application control functions are given in BS EN 13611.
Primarily in industrial applications, it is common practice to rate the safety of a plant-based on values describing the likelihood of a dangerous failure. These values are being used to determine Safety Integrity Levels or Performance Levels when the system is being assessed in its entirety.
To be able to provide values for the parameters that are needed for the determination of a Safety Integrity Level (SIL) or of a Performance Level (PL), BS EN 13611 specify a possible methodology to derive values for the relevant parameters from the requirements. Using BS EN 13611 you can specify the general safety, design, construction, and performance requirements and testing of safety, control or regulating devices.
