In the IEC 60204 standard published by the International Electrotechnical Commission (IEC), Within the scope of machine safety, the requirements for the safety of the electrical equipment of the machines are explained. This standard consists of the following parts:
The EN IEC 60204-1 standard applies to electrical, electronic and programmable electronic equipment and systems for machines that are not manually portable in operation, including a group of machines working together in a coordinated manner. The equipment covered by this standard starts at the point where the supply is connected to the electrical equipment of the machine. The latest update of this standard contains significant technical changes compared to the previous standard. Namely,
The EN IEC 60204-3-1 standard applies to both electrical and electronic equipment of sewing machines, sewing units and sewing systems designed specifically for professional use in the sewing industry. This standard applies to equipment for industrial, commercial or laboratory purposes, but not for home applications. More details on this subject are in the standard “IEC 60335-2-28 Special rules for sewing machines”. The IEC 60204-3-1 standard applies to sewing units and systems installed in dry and well-maintained clean places (for example, for units and systems used in the clothing industry and for the processing of dry sewing materials). Where sewing units and systems are used outside of dry and well-maintained clean locations, more stringent measures to be agreed upon are required.
Standard EN IEC 60204-11 applies to electrical and electrical equipment for machines, including a group of machines operating in coordination with rated voltages above 1000 Volts AC or 1500 Volts DC and not exceeding 36 kV AC or direct current, with rated frequencies not exceeding 60 Hz. Applies to electronic equipment and systems. The latest update of this standard contains significant technical changes compared to the previous standard. Namely,
In short, the EN IEC 60204-11 standard has been developed and updated to reflect the evolution of high-voltage equipment reflected in the standards.
The EN IEC 60204-31 standard applies to electrical and electronic equipment, sewing machines, units and systems specifically designed for professional use in the sewing industry. This standard applies to electrical equipment or parts of electrical equipment operating with rated supply voltages not exceeding 1000 Volts for alternating current and 1500 Volts for direct current and rated frequencies not exceeding 200 Hz. The latest update of this standard contains significant technical changes compared to the previous standard. Namely,
The EN IEC 60204-32 standard applies to electrical, electronic, programmable electronic equipment and systems for lifting machinery and related equipment, including a group of hoists working together in a coordinated manner. The term electrical in this standard includes both electrical and electronic aspects, ie electrical equipment means both electrical, electronic and programmable electronic equipment. Equipment covered by this standard is part of the IEC 60204 standard.The equipment covered in section u starts at the connection point of the feed to the electrical equipment of the hoisting machine and includes systems for the power supply and control feeders located outside the hoisting machine, such as flexible cables or conductive wires. The requirements for the electrical supply installation of the electrical equipment of a lifting machine are contained in the IEC 60364 standard. This standard applies to equipment or parts of equipment that do not exceed 1000 Volts AC or 1500 Volts DC between lines and whose rated frequencies do not exceed 200 Hz.
Every type of lifting machine has requirements that must be met to ensure adequate safety. This standard does not cover noise risks and vibration risks. Additional and special requirements may apply to the electrical equipment of lifting machinery, including:
For the purposes of this standard, lifting machinery includes cranes of all types, and storage and retrieval machinery (e.g. overhead cranes, mobile cranes, tower cranes, slewing luffing cranes, gantry cranes, offshore cranes, floating cranes, lifts and accessories, loader cranes). , cable cranes, load holding devices, monorail cranes, straddle carriers and rubber tire gantry cranes.
The EN IEC 60204-33 standard applies to electrical and electronic equipment associated with semiconductor manufacturing equipment for the manufacture, measurement, assembly and testing of semiconductors. This standard is 1000 Hz with nominal supply voltages not exceeding 1500 Volts for alternating current and 200 Volts for direct current. It applies to electrical equipment or parts of electrical equipment that do not exceed the rated supply frequencies.
