    Assembly made of CE-certified components

    In general, if you are a producer or an OEM, then you need to certify the equipment that YOU sell under YOUR (company) name. This means that if your equipment or device is an assembly of other parts and components, it doesn't matter what certifications the parts and components have, you need to...

    Hazardous area equipment repair requirements

    Give UL's hazardous locations a call. Start with 877-854-3577 (cust service) and ask for an engineer or technical reviewer in that department (I believe they are in Northbrook, IL). Have your UL file # ready for reference. FYI - the NEC is now up to revision 2008.

    Earth ground question

    I'd suggest a quick view of the NEC (National Electrical Code, or NFPA 70) and UL 508 if you have an industrial product (not sure if there's an equivalent consumer product standard, sorry), for grounding requirements. Typically, a ground connection needs to be identified as such, and there are...

    ETL VS UL VS TUVus

    Well, as others have mentioned, it's all about customer perception. Many people do not realize that there are some ~17 NRTL's in this country. They're still used to the old "UL = USA and CSA = Canada" mentality. What matters to you is how your bottom line will be affected. I'd suggest a...

    Product safety certification for active cable equipment

    I suggest you start with UL (Underwriters Laboratories). Submit a quote for cabling (search their website for the most appropriate product category for cabling with regards to your intended applications). The quote should detail what's involved, as far as testing and cost go. If you have any...

    Reciprocation of UL/FM with ATEX

    Easiest way is probably to submit an RFQ (request for quote) to UL and provide them with all available certifications and test reports that your component has. The UL engineer should be able to return a quote with the cost and test plan for the US approval that you're after. You can then use...

    Class II Group G Explosive Dust

    The 1st thing you want to do is get the area properly classified by a professional. Once the area has been defined, you can then determine what type of equipment you need and where. For example, if a certain area is deemed a Class II, Division 2 environment, then you know all of your equipment...

    Electrical Enclosures

    ps: forgot to mention that if you do have any Routine Test requirements, these are usually spelled out in the ATEX certificate's Schedule. If you don't see anything and would like to confirm, simply ask your Notified Body (BASEEFA).

    Electrical Enclosures

    EN 13980 is just for quality systems. I don't have it in front of me at the moment, but as long as you have an EC-Type certification on your enclosure, then the enclosure is tested and certified as a "type", which is representative of all production units. You may still need to conduct Routine...

    UL Certification

    Whether or not a UL engineer says "ok" over the phone is irrelevant and will never fly during an audit inspection. A UL Manager may be able to negotiate a decent price with you if the change does not affect form/fit/function, but either way, you're still supposed to open a project and wait for...

    Are all components in a UL listed product UL Recognized/Classified?

    Depends on how you look at it, but the answer to your comment is yes and no. Do some components need to be Recognized? Yes. Do these components have to be Recognized from their manufacurers? No. I can't speak for every piece of equipment out there, but in general, those which require R/C...
