IEC 61010-1 is the international safety standard for electrical equipment for measurement, control and laboratory use. It defines requirements for design, construction, and testing to reduce risks such as electric shock, fire, mechanical hazards, and unexpected operation. Key topics include:
The 3rd edition (and the currently accepted 4th edition updates) expanded its scope to cover equipment used in both professional and non-professional environments. It applies to three main categories:
For test and measurement equipment connected to mains power distribution systems, IEC 61010-1 references specific Measurement Categories. These categories define the equipment's ability to withstand transient overvoltage spikes (surges) from the power grid.

is an international standard published by the International Electrotechnical Commission (IEC). It specifies the general safety requirements for electrical equipment, ensuring that hazards to the operator and the surrounding area are reduced to a tolerable level. The standard focuses on protecting against: Electric shock and electrocution. Mechanical hazards (moving parts, stability). Spread of fire from the equipment. Excessive temperatures (surface hot spots).
