Note1) A critical component is one whose failure to function or perform
may reasonably be expected to result, whether directly or indirectly, in the
loss of the safety or effectiveness of the device or system containing it,
and which must therefore meet very high standards of performance and
reliability.
Note2) A hazard related device or system is one designed or intended for
life support or maintenance of safety or for applications in medicine,
aerospace, nuclear energy, or other fields, in which its failure to function
or perform may reasonably be expected to result in loss of life or in
significant injury or damage to person or property.
