Question:
If safety is dependent on Software, what criteria do laboratories employ to ensure

Decision:
1 I1 z6 c# x: q; @( ?* n. ISoftware safety is not specifically addressed in IEC 61010-1 at present and therefore, there
are no specific guidelines for this work. A draft collateral standard is in preparation and also
5 g4 |) e( r2 G# \! lIEC 61508 deals with this topic.
Generally, it is advised that devices should not be dependent on software alone for their
safety. There should be a separate independent means provided which acts to prevent a
dangerous condition arising.
