Environmental Certification for a Sensor? 1

[DRWeig]

I'm confused on environmental certifications for things that arent't specifically enclosures, and that fall into the category of Class 2 circuits. I couldn't find a catch-all forum in codes/standards/certifications with any traffic, hope y'all can help me out.

This comes up often in my business. The marketing team would like us to certify that a self-contained apparatus (for example, an RTD temperature sensor potted with epoxy in a stainless steel probe) is NEMA 4 or IP68 or UL Type 4. My feeling is that those are all applicable to electrical enclosures, not for items like this. But, I'd like to help them out.

Product has been marketed for 25 years as weatherproof, waterproof.

Example is attached.

My question is, what is applicable (if any), and how would you proceed if so?

I know I can send to UL for some $$. I think we can test in-house for NEMA. I don't know what to do or where to go for IP, so a hint would be welcome there, too.

Thanks!

Good on ya,

IP68.. sure that would be applicable to an RTD. IP68 is based on IEC60529 and anyone that certifies to that can test/approve your product. UL/ETL/CSA could/should all test to that.

NEMA 4 is for enclosures and should not apply at all no matter what marketing thinks.
Many times "marketing" wants a list of certifications behind a product to make their job easier in hopes that the certification list alone will sell a product.

I would simply call your favorite testing agency and ask about IP68 certifications.
