Organization: ULS
Publication Date: 22 December 2016
Status: active
scope:

607300-000020-000060

1 Scope

Replacement:

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 multi-functional 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.

Modification of the first paragraph of 1 of the part 2 by adding the following:

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.

1 1.1 Replacement:

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.

See also Annex J.

1 1.2 Addition:

This standard applies to automatic

ELECTRICAL CONTROLS

, mechanically or electrically operated, responsive to or controlling a pressure or vacuum.

1 1.3 Not applicable.

1 1.4 Replacement:

This standard applies to

MANUAL CONTROLS

when such are electrically and/or mechanically integral with pressure

SENSING CONTROLS

.

NOTE Requirements for manual switches not forming part of an

AUTOMATIC CONTROL

are contained in IEC 61058-1.

1 1.5

Replacement:

This standard applies to a.c. or d.c. powered pressure

SENSING CONTROLS

with a rated voltage not exceeding 690 V a.c. or 600 V d.c.

1 1.6

Replacement:

This standard does not 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 it 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 shall apply.

1 1.7

Replacement:

This standard applies also to pressure

SENSING CONTROLS

incorporating

ELECTRONIC DEVICES

, requirements for which are contained in Annex H.

This standard applies also to pressure

SENSING CONTROLS

using NTC or PTC

THERMISTORS

, requirements for which are contained in Annex J.

Additional subclauses:

1 1.101 This standard contains requirements for electrical features of pressure

SENSING CONTROLS

and requirements for mechanical features that affect their intended

OPERATION

.

NOTE Subclause 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 series, if applicable.

1 1.102 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 standard also covers these

CONTROLS

when they are independently mounted.

IN-LINE CORD CONTROLS

are not covered by this standard.
