Re: [PSES] CE for military aeronautical product

A mil product has to meet a mil limit, such as MIL-STD-461, DEF STAN 59-411, some NATO STANAG, something. But not CE, and also whether or not ROHS applies it is hardly an alternative for some sort of EMC qualification. Ken Javor Phone: (256) 650-5261 From: Amund Westin

Re: [PSES] Uncertainty Measurement Calculations [General Use]

Concur, as tolerance is not same stuff as uncertainty. But have seen uncertainty calculations as an additional requirement in some customer specs where MS461 was the referenced standard. Just use the test lab's numbers that are on their ISO17025 registration, which Mr. Javor referenced for

[PSES] Uncertainty Measurement Calculations [General Use]

Hi all Can anyone shed some light on working up the Uncertainty Measurement Calculations based on UKAS Lab34 for MIL-STD-461 CS115 and CS116. I need to show the uncertainty values for these tests as follows: Uncertainty in overall test level = 2.2dB, Uncertainty in time measurement = 1.91%,

Re: [PSES] Criteria for determining industrial vs. non-industrial for EMC testing purposes

I'm not unsure. Class A is for heavy industry, powered from MV or higher, with no broadcast receivers likely within 30 m. The real difference between Europe and the Americas is that in Europe, there is a vain attempt to prohibit the use of Class A devices out of industrial areas, whereas in

Re: [PSES] Working towards compliance as per the EN 55032

Re: [PSES] CE for military aeronautical product

When the military (the UK MoD) makes a purchase, it is done as a contract between MoD and the vendor. The MoD can impose any requirement it wishes as a condition to the contract. Most of the time, a Test Procedure is a contractually required line item, and must be submitted to the MoD for

Re: [PSES] Uncertainty Measurement Calculations [General Use]

It couldn¹t be easier. MIL-STD-461 has no uncertainty requirements whatsoever, and anyone trying to mandate such has no military heritage authority to do so. The only accuracy-type requirement in MIL-STD-461 is the measurement system integrity check, performed right before making each pertinent

Re: [PSES] Criteria for determining industrial vs. non-industrial for EMC testing purposes

Jamison, IMO, it’s the sharing of the supply with domestic establishments that is the key to the application of the definition of the classes. Clearly, a large industrial facility could be fed at MV and have MV loads as well as LV loads, so the question of whether there is a substation or not

Re: [PSES] Criteria for determining industrial vs. non-industrial for EMC testing purposes

1. Yes. 2. Original statement is true only if the substation output is at MV or higher. If it is at LV, the location is strictly RCLI (residential, commercial and light industrial). a) In most countries in Europe, yes, but in France there are some separate industrial LV networks. You have

Re: [PSES] Criteria for determining industrial vs. non-industrial for EMC testing purposes

Doug- Thanks very much for this. Within this group, I often get responses before the initial email, so I missed this one the first time through. Two questions: 1. Is it safe to say that the same definitions hold true for immunity as well? 2. Would the following statements be true

Re: [PSES] Criteria for determining industrial vs. non-industrial for EMC testing purposes

John, You bring up a good point, in that we see rural properties in North America where a single farm is fed with it’s own transformer from an MV line at say 4.8 kV to LV, and that farm is the only load on the the transformer. Is that an RCLI situation? IMO yes, because the family lives there

Re: [PSES] Uncertainty Measurement Calculations [General Use]

It appears that regardless of the total lack of uncertainty type requirements in MIL-STD-461, certain people/organizations nevertheless mandate such - as I pointed out, without a shred of any military heritage/authority to do so. There is some economic rationale (level playing field) for

Re: [PSES] Uncertainty Measurement Calculations [General Use]

Any claim for uncertainty must be based on the lab's published numbers per their accreditation and registrations. But have seen some rather creative math from some labs where the particular test method was considered outside of their scope statement. And all compliance engineering people are

Charlie, They are using the “test to harmonized standards” route. Read the original post. That said, as you note, EN 55022 is no good after March 5, 2017. I doubt they want to change approaches to meeting the essential requirements in the EMC Directive, so showing compliance with EN

[PSES] CE for military aeronautical product

As far as I understand, military products shall be CE marked when used in Europe. What will be the case when CE marking a military computer used in a military aircraft? LVD does not apply (low DC voltage) and RTTE/RED does not apply because there is no wifi or any radio module inside. For

Re: [PSES] Criteria for determining industrial vs. non-industrial for EMC testing purposes

Interesting. In North America, it’s not uncommon to see multi-unit industrial buildings where the supply is shared, so this would be Class A under EN 55011 as there is no domestic establishments sharing the supply, but reasonably could be called as RCLI I think, despite that. We also see
