5.1 Products that use safety functions shall be investigated with the same safety testing related to a single fault fire hazard, shock hazard, or energy hazard. In addition, a risk assessment shall be prepared to review software safety functions and the mitigation measurements to prevent them from experiencing a single fault failure. CSA C22.2 No.0.8 shall be used for evaluation to investigate the safety functions.
5.2 All functional safety analysis shall include
a) list of the safety functions involved;
b) a risk assessment; and
c) a description of the mitigation measurements introduced to mitigate the risks identified.
6.1 A unit intended exclusively for dry locations shall be identified as such, and shall not be provided with any information (e.g., markings, instructions, or ilustrations) that implies or depicts damp or wet use.
6.2 A unit intended for damp locations shall be
a) subjected to the environmental tests of Clause 9.12 unless all live parts and traces on the printed circuit board are potted (see Clause 7.7) or conformal coated (see Clause 8.7.2);
b) if provided with a polymeric enclosure, comply with the Polymeric lmpact Test in Clause 16.41 of CSA C22.2 No. 250.0, using a preconditioning temperature of 0±2.0°C (32±3.6°F); and
c) eligible to be marked as suitable for damp locations, and not be provided with any information such as markings, instructions, or illustrations that implies or depicts wet use.
A circuit operating at Class 2 or LED Class 2 power levels (see Annex A) in which voltage levels are below those that present a risk of electric shock (see Clause 3) is not required to be subjected to Items (a) and (b) above.
6.3 A unit intended for use in wet locations shall
a) be subjected to the environmental tests of Clause 9.12 unless all live parts and traces on the printed circuit board are potted (see Clause 7.7) or conformal coated (see Clause 8.7.2),
b) if provided with a polymeric enclosure, comply with the weatherometer test of CAN/CSA-C22.2 No 0.17 and with the Polymeric Impact Test in Clause 16.41 of CSA C22.2 No.250.0, using a preconditioning temperature of minus 35.0±2.0°C (minus 31.0±3.6°F), and
c) be eligible to be marked as suitable for wet locations.
A circuit operating at Class 2 or LED Class 2 power levels (see Annex A) in which voltage levels are below those that present a risk of electric shock (see definition in Clause 3) is not required to be subjected to Items (a) and (b) above.CSA C22.2-NO.250.13 pdf download.
