IEC 62368-1 Audio/video, information and communication technology equipment - Part 1: Safety requirements

ConsultingOn December 20, 2020 the seasoned harmonized standards IEC 60950-1 and IEC 60065 will lose their presumption of conformity and will be replaced by IEC 62368-1 und EN 62368-1.

Until then it is advised to reassess all relevant products pursuant to IEC 62368-1 to further be able to confirm compliance with RED (Radio Equipment Directive) or LVD (Low Voltage Directive).

Thanks to these changes in standards philosophy away from technology-focused catalogues to a hazard-based approach, it now is easier to equally assess varying products.

For instance, hazards are categorized by type and „size“ of the according energy source:

  • electrical
  • mechanical
  • power
  • radiation
  • thermal

The core area electrical energy source encompasses high-voltage testing, leakage-current measurements, protective conductor measurements for products connected to the public power grid. Especially the isolation coordination as implemented by the manufacturer is put to the test.

Glow Wire TestingFurther, indirectly-involved hazards regarding electrical energy sources find themselves in the converted or available power–read: fire–and contact temperatures at accessible locations. To do this, products are run in their intended and abnormal environments, as products must prove themselves in single-fault conditions. Finally, it may be confirmed whether or not the regulations on reducing a possible ignition are fulfilled or if a fire protection enclosure is required.

Besides that, contact temperatures are monitored to ensure thresholds are kept in all cases, where requiring a warning sign or a corresponding protection is not intended.
