【Safety Certification】The Insulations in Product Safety Standards

The basic definitions for Insulation in Product Safety Standards:

• Basic Insulation

insulation applied to live parts to provide basic protection against electric shock.
 

• Supplementary Insulation

independent insulation applied in addition to basic insulation in order to provide protection against electric shock in the event of a failure of basic insulation.
 

• Double Insulation

insulation comprising both basic insulation and supplementary insulation.
(1 Double insulation = 1 Basic insulation + 1 Supplementary insulation)
 

• Reinforced Insulation

single insulation system applied to live parts, which provides a degree of protection against electric shock equivalent to double insulation.
(1 Reinforced Insulation effect = 1 Double insulation effect)
 
[Note] live part
conductive part which may cause an electric shock in normal use.
