Surface temperatures are restricted to prevent burns, aligning with the EN 563 standard. 4. Testing and Measuring Circuits (Clause 16)
For testing and measurement equipment, IEC 61010-1 establishes "Measurement Categories." These ratings define the level of transient overvoltage (voltage spikes) a tool can safely withstand when connected to utility grids. Description Typical Examples Loads connected to single-phase AC outlets. Appliances, portable tools, household electronics. CAT III Distribution-level wiring and fixed installations. Three-phase buses, distribution panels, lighting systems. CAT IV Origin of the utility installation (outdoor/mains). iec 61010-1 standard pdf
