IEC 60664-5 Insulation Coordination for Equipment in Low Voltage Systems - Part 5: Clearances and Leakage Distances of 2mm or Less

The IEC 60664-5 standard defines the sizing of the gaps and where the Clearance and leakage distance are the same and along the solid insulation surface such as example 1, example 5 and the paths described in the example, leakage equal to or less than 2 mm for gaps for printed wiring board and equivalent structures. distances Part 1 Sizing is more precise than provided by Part 1.

If the precision provided by this standard is not required, Part 1 may be applied instead. This standard can only be used as a whole. It is not allowed to select one or more items from this standard and replace them with the relevant clauses of Part 1.

When this standard is applied to the dimensioning of gaps and leakage distances, Part 1 applies to all materials, the corresponding clauses given in Part 2, clearances and leakage distances greater than 1 mm, and solid insulation in general. The limitation on distances less than or equal to 2 mm applies to basic or supplementary insulation. The total distance of reinforced or double insulation can be greater than 2 mm.

This standard is based on the following criteria for sizing:

• Minimum gaps independent of microenvironment
• Minimum leakage distances for pollution degrees 1, 2 and 3 to avoid failure due to monitoring
• Minimum leakage distances to prevent splashing along the insulation surface

This standard does not apply to microenvironmental conditions worse than pollution degree 3 or humidity level 3. A test method is specified for assigning unclassified insulation materials to the corresponding water adsorption group.
