What is IEC 60335-2-73 ?

IEC 60335-2-73: Safety Requirements for Robotic Floor Cleaning Machines

Robotic floor cleaning machines are becoming increasingly popular in commercial and industrial settings due to their efficiency, ease of use, and ability to clean sensitive floors. However, as with any machine, they also pose a safety risk to both users and those around them. IEC 60335-2-73 is an international standard that specifies the safety requirements for robotic floor cleaning machines.

Safety Overview

The primary objective of IEC 60335-2-73 is to ensure the safe operation of robotic floor cleaning machines. The standard provides manufacturers with guidelines for designing and constructing safe floor cleaning machines that meet the necessary safety requirements.

Electrical Components

One of the most critical components of a robotic floor cleaning machine is the electrical system. IEC 60335-2-73 specifies that electrical components, such as motors, control panels, and power outlets, must be designed and installed to minimize the risk of electrical shock.

Insulation

Insulation is also an essential component of a safe robotic floor cleaning machine. IEC 60335-2-73 requires that all electrical components, including motors and control panels, be installed with appropriate insulation to prevent electrical currents from flowing through the body or into the environment.

Protection Against Electric Shocks

Electric shock is one of the leading causes of death and injury in robotic floor cleaning machines. IEC 60335-2-73 specifies that all electrical components must be designed and installed to protect against electrical shocks. This includes the use of fuses, circuit breakers, or other forms of electrical protection.

Mechanical Strength and Stability

Robotic floor cleaning machines must also be designed and constructed to withstand the forces generated by their operation. IEC 60335-2-73 specifies that all parts of the machine must be designed and installed to ensure stability and mechanical strength, and that the machine as a whole must be designed to minimize the risk of tipping over or falling over.

Thermal Protection

Robotic floor cleaning machines can also pose a thermal hazard if not properly designed and installed. IEC 60335-2-73 specifies that all electrical components must be designed and installed to prevent overheating, and that the machine must be designed to dissipate heat effectively.

Safeguarding Against Specific Hazards

Finally, IEC 60335-2-73 specifies that all robotic floor cleaning machines must be designed and installed with safeguards against specific hazards, such as fire or the release of hazardous substances. These safeguards may include the use of flame-resistant materials, emergency stop mechanisms, or other forms of safety protection.

Conclusion

IEC 60335-2-73 is an essential standard for the safe operation of robotic floor cleaning machines. By following the guidelines and requirements set out in this standard, manufacturers can ensure that their machines are designed and installed for the safety of users and others.
