WG 3 - TC 44/WG 3

Applies to the electrical and electronic equipment and systems of machines, including a group of machines working together in a coordinated manner, but excluding higher level system aspects (i.e. communications between systems).

Applies to the electrical and electronic equipment of industrial machines. Promotes the safety of persons who come into contact with industrial machines, not only from hazards associated with electricity (such as electrical shock and fire), but also resulting from the malfunction of the electrical equipment itself. Addresses hazards associated with the machine and its environment. Replaces the second edition of IEC 60204-1 as well as parts of IEC 60550 and ISO 4336.

Specifies safety-related requirements for actuators, operated by the hand or by other parts of the human body, at the man-machine interface. Gives general requirements for: - the standard direction of movement for actuators; - the arrangement of an actuator i relation to other actuators; - the correlation between an action and its final effects. Based on IEC 60447, but is also applicable to non-electrotechnical technologies. Covers single actuators as well as groups of actuators forming part of an assembly.

Applicable to equipment or parts of equipment not exceeding 1 000 V a.c. or 1 500 V d.c. between lines, and with nominal frequencies not exceeding 200 Hz. Additional and special requirements can apply to the electrical equipment of hoisting machines that are used in potentially eyplosive and/or falmmable atmospheres. Does not cover individual items of electrical equipment other than their selection for use and their erection.

Specifies requirements for the design, construction and testing of electro-sensitive protective equipment (ESPE) for the safeguarding of machinery, employing active opto-electronic protective devices (AOPDs) for the sensing function. Special attention is directed to features that ensure an appropriate safety-related performance is achieved. Is restricted to the functioning of th ESPE and how it interfaces with the machine.

Specifies general requirements for the design, construction and testing of electro-sensitive protective equipment (ESPE) for the safeguarding of machinery. Special attention is directed to functional and design requirements that ensure an appropriate safety related performance is achieved. Restricted to the functioning of the ESPE and how it interfaces witht he machine.

Specifies requirements for visual auditory and tactile methods of indicating safety related information. Specifies a system of colours, safety signs, markings and other warnings, intended for use for the indication of hazardous situations.
