Hi,
Does IEC 62368-1 Require 100% Electric Strength (Hipot) Testing?
IEC 62368-1 does not mandate 100% electric strength (hipot) testing for all
units during production. Instead, the standard allows sampling based on a risk
assessment, particularly for routine production testing.
Key Points:
*
Type Testing: Performed representative samples during product certification to
validate design compliance. This includes full dielectric strength testing.
*
Routine Production Testing: Intended to detect manufacturing defects rather
than revalidate insulation. Sampling is permitted based on a documented risk
assessment and quality control procedures.
*
Risk-Based Approach: The standard supports a hazard-based philosophy, allowing
manufacturers to determine appropriate testing strategies (e.g., sampling vs.
100%) depending on the risk level and production controls in place.
*
Component Use: Certified components used within their rated conditions may not
require additional hipot testing at the end-product level.
In summary, IEC 62368-1 allows for sampling in place of 100% testing, provided
it is justified through risk assessment and quality management practices.

IEC 62368-1 is about requirements. For testing products in production, you need
to look at IEC 62911.

Hi All,
Could you please confirm whether IEC 62368-1 requires 100% electric
strength (hipot) testing for all products, or if sampling is allowed based on a
risk assessment?
