RE: Sanity check on AC motors for boat use
Good point, however these will be on recreational craft in most cases. I'm
told US, Canada, Australia and then EU are the markets.

Subject: Re: Sanity check on AC motors for boat use
Depends upon what is meant by a "Boat"
A Recreational Vessel or a Commercial Vessel?
I would think the later needs to conform to requirements of the International
Association of
Class Societies E10 standard. Or more particularly perhaps to the standards of
the actual Class
Society (Lloyds Register, American Bureau of Shipping, etc.) who is approving
the design and
construction of the vessel.
YMMV

In reviewing standards as applicable to DC powered (battery) motors for use on
boats, as I’m
seeing it that applicable EMC directive standards to apply would be EN55012 and
EN55014-2.
EN55014-1 excludes devices used exclusively in vehicles. Another route to go
would be in
looking at EN61000-6 series for immunity. I think the emissions requirement is
very straight
forward. A long I/O or control line in addition to the DC power cables causes
a pause for
thought, but is easily tested and addressed in EN55014-2.
Thoughts?

semi-anechoic chambers and smoke alarms
Good morning, I’ve got a question for the chamber experts and experienced folk here. Please respond off-line unless it would be to the betterment of the group at large. We’ve just received the results of a business insurance audit. The only area of our building with a fire suppression system/monitored smoke alarm system is the 10m semi-anechoic chamber, essentially an ETS FACT 10 with TDK Closed cell Styrofoam over ferrite tiles. As we were walking through the facility, we had the turntable open, the auditor inquired as to the reason. My response when she asked the questions as to why it was opened was ”I don’t know, I’ll have to look into it”, and then she did not follow up and I did not further answer. The reason to the curious, was to move some auxiliary equipment placed there during testing and to unplug the 160A service to the EUT. We have since received her recommendation letter. In which she recommends “In order to promptly notify the fire department in the event of a fire, an approved fire detection system should be installed in all areas of the building including below the elevated floor in the Semi-anechoic chamber, in accordance with the latest edition of NFPA 72 National Fire Alarm Code, and alarm signals should be automatically transmitted to a UL listed central station or directly to the fire department or public dispatcher.” The general fire detection portion I’ve always wondered why it was never installed, but under the raised floor of the chamber? The questions: 1) Why is a 10m chamber required to have a fire suppression system when testing is monitored (or should be as some of the last posts point out), any personnel in the room have 2 exits, there is normally not any personnel in the chamber, and besides the EUT, is there any combustible material in the room? 2) In the crawl space under the floor, besides the turntable motor, ODE converter, power receptacles and occasionally auxiliary equipment, is there anything that is combustible?

RE: Recommendations requested: Water chiller companies in N. California
Do you mean expensive to operate, not purchase. I would guess in the system in question it is a dual stage system, where one compressor cools the low stage and the other compressor is water cooled and the water cooler has an air cooled compressor. Who you purchase the unit from and who services it for you can be 2 completely different groups. We have chambers from Ransco, Thermotron and Russells. We use a local HVAC company that has a skilled ultra-low temp tech, as we have 2 dual stage systems(-65C). If it is a dual stage system, make sure the HVAC company has a guy that does the ultra-low, it is a different skill set and the untrained will cost you time and money figuring out how the system actually works. An environmental chamber is a fancy beer cooler/humidor/meat locker/sauna/steam room/warming oven. A water chiller still uses simple refrigeration/HVAC principles.

There are several HVAC and electrical companies in the Valley that do that sort of work. The key words are HVAC not water chillier. They are as close as the Yellow Pages. I don't know what kind of testing you are doing but chilled water is not normally used because it limits the low end to about 4 degrees C. If you are talking about water cooled mechanical that can be attached to some existing HVAC systems. The choice of systems is highly dependent on volume and range. N2 and CO2 systems are widely used for shocking and are easy to setup. They are expensive relative to mechanical so they are not normally used for production.

RE: IECEE and CE
Is there a listing anywhere of countries that officially accept CB-scheme reports in lieu of local testing? The key being "officially". -Doug From: emc-p...@ieee.org [mailto:emc-p...@ieee.org] On Behalf Of Nick Williams Sent: Monday, November 17, 2008 10:16 AM To: Doug Kramer Cc: emc-p...@ieee.org Subject: Re: IECEE and CE Only the CE mark is mandatory in the EU. All other marks (for equipment covered by the CE marking directives, at least) are optional, but they can have market advantages and assist with product liability insurance. In the days before the CE mark, some EU countries required vendors of electrical equipment to have their products tested by a state or commercial test house before they could legally be sold in their territory. The CB Scheme was partly invented as a means of helping to sustain the business models of the organisations which previously made a living from mandatory testing once self-certification was introduced under the Low Voltage Directive. The primary value of the CB scheme is that if you are of a mind to obtain approvals in a number of different territories then it can avoid the need for expensive testing to be repeated in every case. Because the scheme extends worldwide, it has particular value to vendors selling in multiple non-EU markets where third party testing is still mandatory since it allows a manufacturer to get testing done in their own territory (or another where they are already familiar with the requirements, language etc.) and to a large extent avoid having to working with unknown quantities on the other side of the plant.

IECEE and CE
In looking over some information for a customer, I came back to the IEC’s IECEE section of their website. “The fundamental principle of the CB Scheme is that a manufacturer can obtain a CB Test Certificate for a defined product, from a national certification body (NCB). The manufacturer can then present this certificate to the NCBs in other member countries whose certification marks he wants for his products. The CB Scheme is based on the principle of mutual recognition by its members of test certificates for the purpose of issuing third-party certification marks at national level. The members of the scheme commit themselves to recognize the CB Test Certificate issued by any Certification Body accepted by the CMC to operate within the scheme. An essential part of this is peer assessment. Experience shows that in addition to promoting confidence among the members of the CB Scheme, Peer Assessment, as a method to verify competence and build confidence is accepted by authorities and clients of testing and certification bodies as having at the least same value as accreditation.“ (http://www.iec.ch/conformity/ab_iecee.htm) I thought that manufacturers testing using harmonized standards (when available) was a correct route to demonstrating compliance to the EU directives and that CE-marking was only mark needed. Am I getting marking confused with national and international levels? And what would be an example of a difference? It also seems that the CB-scheme is promoting as an alternative to accreditation?

Safety of high ouput LEDs
On a similar vein as the laser discussions: Are there any safety requirements for high output (low voltage/power) LEDs for use in household lamps? US and EU are the focus de jour. In my simple research the answer has been no. The standards for previously used lamps exist, but not LEDs. Is there anything in the works? The design uses a CE-marked, NRTL approved AC-DC SMPS, 36VDC output. Regards, Doug Kramer - This message is from the IEEE Product Safety Engineering Society emc-pstc discussion list.
