Fax Machine Certified for Aircrft use?
Fax Machine Certified for Aircrft use?
(OP)
Is there any vendor can provide the Multi Function (copy, fax, print, scan) machine, that has already specifically certified for aircraft usage?
Hundreds of Multi-purpose machines are available for comercial use. But I can not find even one specifically certified for aircraft.
Do you ever install a Fax Machine to aircraft, does fax machine is already certified?

We install COTS fax machines in an enclosed compartment under conditions established with our lcoal FAA ACO via an issue paper.
In addition to ELA and EMI considerations, there is the flammability issue to deal with.

I am not saying there is no such thing as a fax machine that is specifically designed for aircraft use, but what I am saying is we have never located (or needed) one.

The flammability and ELA is easy for my company. And aircraft level EMI/EMC test (STC Test Plan) is also within my company's capability.
As all your comment, the component level EMI/EMC test per DO-160E is also required. Here has some difficulties to do this test:
1. The Fax machine available in the market is updated frequently.
2. DO-160E is more stringent than other commercial standard. Some Fax model may need to be modified.
3. DO-160E EMI test is expensive than buying an already tested products.
We all agreed that there is no fax specifically for aircraft.
But is there any Brother Multi-Function Center, which has already passed DO-160E EMI/EMC test without modification? Or what Brother Fax Machine models you has adopted before?
And which company can supply such models with DO-160E EMI/EMC test report?
Thanks so much for you all again.

Most importantly, does your MFC-465CN ever sent to Lab for DO-160E EMI/EMC test?

Recently I was working on a Boeing project, where we did some mech. provisioning for an MFC-9070 to be installed.
We install the fax machine as COTS which means that it has not been RTCA DO160 tested, as far as I know. But this is not my area, and I do not want to say something which is not true. I am sure that there are some Certification Engineers out there, who could be more helpful...

Will someone be sitting close to the fax/copier? Within a certain radius, you must consider headstrikes against sharp edges. Especially if your EMI enclosure is a bent-up sheet metal box.
Think carefully about 25.853... it doesn't seem like you have, otherwise you wouldn't have brushed it off so casually. I won't elaborate yet, because if I explain myself, everyone is going to jump. There are means of mitigating each of the issues, but you should brace yourself for a very strict interpretation of the FAR's from the ACO.
Just because others have had an "easy go" doesn't mean that you will.
Good luck!

I am focus on the DO-160E EMI/EMC issue. As SparWeb indicate, there should have means of mitigating such issues.
As CoffinsCorner indicate, the Fax Machine is as COTS and not been DO-160 tested.
While, without DO-160 EMI/EMC test, what is the acceptable means of compliance of FAR 25.1353(a), FAR 25.1431(c), and AC 25-10 (dated 3/6/87) Para 5.f?
Thanks so much,

We always do a EMI test, substantiation analysis for Loads and retention (items of mass).
If the machine is located in an enclosed space like a draw or cabinet, the enclosure must be lined with a non-flammable material and sometimes we have installed a squib type extinguisher (the same type we use in trash containers in the lavatories.
All the Fax machines have been COTS, listed on a COTS report and are not eligible for PMA
Hope this helps
