Common Standard/LowE
Agreement for interchangeable testing


LowE unit tests already test standard as an option
Introduce LowE option into
examples/extended/electromagnetic/TestEm*
Discussion on design iteration in the eloss domain
Discussion on future cycles of design iteration
Discussion on the right to exist of the LowE WG

GEANT4 LOW ENERGY ELECTROMAGNETIC PHYSICS
Overview of procedures
for design, development,
tagging, testing
Defect analysis and
prevention

Based on data collected in the
work phase for the June
release
UR form
Both incomplete and
redundant for LowE
requirements, according to past
experience
