UL Standard for Safety Automatic Electrical Controls – Part 2-6: Particular Requirements for Automatic Electrical Pressure Sensing Controls Including Mechanical Requirements
|Publication Date:||22 December 2016|
This part of IEC 60730 applies to automatic electrical pressure SENSING CONTROLS with a minimum gauge pressure rating of -60 kPa and a maximum gauge pressure rating of 4,2 MPa, for use in, on or in association with, equipment. The equipment may use electricity, gas, oil, solid fuel, solar thermal energy, etc. or a combination thereof.
NOTE Throughout this standard, the word "equipment" includes "appliances" and "control system".
This standard is also applicable to individual pressure SENSING CONTROLS utilized as part of a CONTROL SYSTEM or pressure SENSING CONTROLS which are mechanically integral with multifunctional controls having non-electrical outputs.
Automatic electrical pressure SENSING CONTROLS for equipment used by the public, such as equipment intended to be used by laymen in shops, in light industry and on farms, are within the scope of this standard.
This standard does not apply to pressure SENSING CONTROLS intended exclusively for industrial process applications unless explicitly mentioned in the relevant equipment standard
This part of IEC 60730 applies to automatic electrical pressure SENSING CONTROLS for use in, on or in association with, equipment. The equipment may use electricity, gas, oil, solid fuel, solar thermal energy, etc. or a combination thereof.
This standard applies to inherent safety, OPERATING VALUES, OPERATING SEQUENCES where such are associated with equipment protection, and to the testing of automatic electrical pressure SENSING CONTROLS used in, on or in association with equipment.
This standard is also applicable to the functional safety of low complexity safety related pressure SENSING CONTROLS and SYSTEMS.
This standard is also applicable to pressure SENSING CONTROLS for appliances within the scope of IEC 60335-1.
