Anotace obsahu normy

This clause of Part 1 is replaced by the following:
This document applies to automatic electrical pressure sensing controls
- for use in, on, or in association with equipment for household appliance and similar use;
NOTE 1 - Throughout this document, the word "equipment" means "appliance and equipment" and "controls" means "pressure sensing controls".
- for building automation within the scope of ISO 16484 series and IEC 63044 series (HBES/BACS);
EXAMPLE 1 - Independently mounted automatic electrical pressure sensing controls, controls in smart grid systems and controls for building automation systems within the scope of ISO 16484-2.
- for equipment that is used by the public, such as equipment intended to be used in shops, offices, hospitals, farms and commercial and industrial applications;
EXAMPLE 2 - Automatic electrical pressure sensing controls for commercial catering, heating and air-conditioning equipment.
- that are smart enabled automatic electrical pressure sensing controls;
EXAMPLE 3 - Smart grid automatic electrical pressure sensing controls, remote interfaces/control of energy-consuming equipment including computer or smart phone.
- that are AC or DC powered controls with a rated voltage not exceeding 690 V AC or 600 V DC;
- used in, on, or in association with equipment that use electricity, gas, oil, solid fuel, solar thermal energy, etc., or a combination thereof;
- utilized as part of a control system or controls which are mechanically integral with multifunctional controls having non-electrical outputs;
- using NTC or PTC thermistors and to discrete thermistors, requirements for which are contained in Annex J;
- that are mechanically or electrically operated, responsive to or controlling a pressure or vacuum;
- as well as manual controls when such are electrically and/or mechanically integral with automatic controls.
NOTE 2 - Requirements for manually actuated mechanical switches not forming part of an automatic control are contained in IEC 61058-1-1.
This document is also applicable to individual pressure sensing controls utilized as part of a control system or pressure sensing controls which are mechanically integral with multi-functional controls having non-electrical outputs.
This document is also applicable to pressure sensing controls for appliances within the scope of IEC 60335-1.
This document applies to
- the inherent safety of pressure sensing controls, and
- functional safety of pressure sensing controls and safety related systems,
- pressure sensing controls where the performance (for example the effect of EMC phenomena) of the product can impair the overall safety and performance of the controlled system,
- the operating values, operating times, and operating sequences where such are associated with equipment safety.
This document specifies the requirements for construction, operation and testing of automatic electrical controls used in, on, or in association with an equipment.
This document does not
- apply to pressure sensing controls intended exclusively for industrial process applications unless explicitly mentioned in the relevant part 2 or the equipment standard. However, this document can be applied to evaluate automatic electrical controls intended specifically for industrial applications in cases where no relevant safety standard exists;
- take into account the response value of an automatic action of a pressure sensing control, if such a response value is dependent upon the method of mounting the control in the equipment. Where a response value is of significant purpose for the protection of the user, or surroundings, the value defined in the appropriate equipment standard or as determined by the manufacturer will apply;
- address the integrity of the output signal to the network devices, such as interoperability with other devices unless it has been evaluated as part of the control system.
This document contains requirements for electrical features of pressure sensing controls and requirements for mechanical features that affect their intended operation.
NOTE - Subclause 20.101, as it pertains to gas and/or oil controls, is under consideration pending review or revision of ISO 22967, ISO 22968 and ISO 23550, if applicable.
In general, these pressure sensing controls are integrated or incorporated with the equipment or are intended to be integrated in, or on the equipment. This document also covers these controls when they are independently mounted. In-line cord controls are not covered by this document.
