CSA C22.2 NO. 0.8:19 (R2024) ✓ Most Recent

This Standard applies to products and component devices where the electronics technology handles the operational logic including the safety features. This Standard applies to the following configurations:
a) safety control function(s) implemented in hardware only; and
b) safety control function(s) implemented in some combinations of hardware and software.

Note: Clauses that are identified by an asterisk define a simplified path for hardware-only designs. For reference, these clauses are listed in Table 2.

The scope of this Standard includes the sensors and actuators that are associated with the safety control. The requirements in this Standard apply to products where failure in either the hardware or software, or any associated devices, can lead to a hazard. See more
