In IEC 60079-15 Table 10 - Minimum creepage distances, clearances and separations, Encapsulated or solid insulation is allowed to reduce the minimum clearance requirements. Note 4 of the table states completely encapsulated in compound to a minimum depth of 0.4 mm. What tests are required to verify this encapsulation? Does the encapsulation need to meet the requirements of IEC 60079-18 Encapsulation, because the requirements for Conformal Coating much simpler? I am trying to dispute MetLab requirement for testing to IEC 60079-18 when the minimum creepage and clearance of a 100-240VAC power supply is 1.0 mm. My understanding is creepage is not considered, if conformal coating or encapsulation is used. Is this correct?
