9/10/2019

0 Comments

 
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.
