These are the geometric safety distances required on a Printed Circuit Board (PCB).
A defining feature of IEC 61010-1 is its use of to define transient withstand capability:
IEC 61010-1 is essential for any manufacturer, importer, or designer of electrical test, measurement, or laboratory equipment. It reduces the risk of fire, shock, and injury while enabling global market access through the CB Scheme. For full compliance, always obtain the official PDF from an authorized standards body and ensure your design and test procedures align with the current edition. iec 61010-1 standard pdf
Common third-party certification marks include:
If you download an IEC 61010-1 standard pdf labeled 2010 without amendments, you are using a partially obsolete document. Always look for "Edition 3.2" or "including Amendment 2:2020". These are the geometric safety distances required on
The values for these distances depend on the (the expected amount of dirt/dust/condensation) and the Overvoltage Category . Engineers spend the most time referencing the tables in Annex D (or equivalent tables in the body of the standard) to determine if their PCB layout is safe.
The next edition (Edition 4.0) is expected around 2027-2028. Anticipated changes include: For full compliance, always obtain the official PDF
The standard now distinguishes between an (trained for correct use) and a responsible body (an organization that oversees safety, maintenance, and abnormal situations). This shifts some safety obligations from the product alone to the organization.
For working voltages above 50 V AC or 120 V DC, insulation must be:
