Acceptable values for parameters inspected during above stage checks are laid down. In case of
parameters not falling in permissible limits, necessary action is taken. Parameters are generally kept
with sufficient safety factors and acceptable tolerance limits. Each component is tested and
document is prepared. If results are acceptable, it is put in service. However, if any component is
beyond the acceptable values it is returned to manufacturer for replacement/ correction. There is a
systematic approach and documentation for the above procedure.
