Safety Add-On Instruction Qualification Tests

Safety Add-On Instruction tests must be performed in a separate, dedicated application to verify that unintended influences are minimized. You must follow a well-designed test plan and perform a unit test of the safety Add-On Instruction that exercises all possible execution paths through the logic, including the valid and invalid ranges of all input parameters.

An independent, third-party review of the safety Add-On Instruction can be required before the instruction is approved for use. An independent, third-party validation may be required for functional safety certification.
