However, there were exemptions granted to products requiring high safety standards in the aeronautical, aerospace, mining, offshore and nuclear industries. Exemptions were also granted for safety devices in road and agricultural vehicles, rolling stock and vessels and electrical contacts in any sector of use. Broadly similar restrictions exist in Finland, Austria and Sweden. The attached pdf taken from the Europa website clarifies.

RE: Pollution Degree vs. Creapage Distance

If so, clause 2.9.6 clearly addresses your question by requiring hermetic sealing or such enclosing to prevent the ingress of dirt and/or moisture. IMHO, solder mask does not and cannot provide this type of protection and, therefore, cannot be used as such. And, as for your question, Why are the secondary circuit spacing requirements based on a primary input voltage?. Look into Annex ZB of the above standard and then to the reference clause 6.2.1.2. Your answer is there as it relates to TNV circuits. Again, this is assuming that you were referring to the above standard. I hope this helps.

It becomes very apparent that the creapage distances become quite large when you assume material group IIIb (CTI). For operational insulation, this might be 2-3X the clearance values. My question to the group is: Does the application of a solder mask allow for a change from pollution degree 2 to pollution degree 1? I understand that conformal coating requires significant testing when used to reduce spacings per table 7, but in this case I am only asking if solder mask can be used to improve the pollution concern. Assuming this is NOT the case, are there any other practical suggestions? Cutting slots in multilayer cards is a bit tricky. I can live with 0.7mm of clearance, but 2.5 mm (operational) or 5.0 (reinforced) of creapage is a bit difficult on a densely populated power supply. One last question. Why are the secondary circuit spacing requirements based on a primary input voltage?

Re: CE Marking - Prototypes
Gregg, My understanding was that LOCAL Code requires its own standard/tests or an NRTL compliant product. For example, the City of Los Angeles used to require (or still does) that equipment placed in the city conform to the city code, or be UL Listed. If this is not correct, I would like to know this!
