Abstract: A technique is presented that provides for a
qualitative and quantitative assessment of the risk of failing
to achieve EMC compliance when making minor hardware
design changes (component or PCB layout) on a product
that has already had a successhl compliance test performed.
The EMC Design Risk Assessment (EDRA) technique uses
a simple summation of risk scheme to allow design changes
to be gauged and the requirement for re-testing to be implied
from the total risk value. The technique allows a product
supplier to make a quantified technical assessment of the
impact of design changes on the compliance status and
hence decide if a retest is required or can be avoided. The
supplier may make the decision to not implement all of the
suggested design changes in order to avoid retest costs an ..
