[PSES] 答复: [PSES] 802.11a (5GHz WiFi) requires CE Alert sign, right?

2014-08-04 Thread Huang, Tim 
5725-5845MHz is not required alert sign. 
For 2.G, alert sign is no longer required since July,1 2012 for EU members, 
before June 30 2012, alert sign was required as in France 2.4G is restricted 
and not harmonized.

Hello Dave,

5 GHz WLAN are indeed Class 2 and do indeed require the Alert Symbol.

The restriction of their use is that they are only permitted indoors in the 
band from 5.15 GHz to 5.35 GHz.

The Commission does provide a short list of typical Class 2 devices that are 
easy to explain.
Look which one is number 1 on the list…   ☺  ….

Hi all,
  I know the 2.4 GHz band for WiFi no longer requires the Alert sign as the 
last restriction on use fell out in 2012, but I have a question on the 5GHz 
bands:

Specifically, if there is an EU-wide restriction on use (indoor use with power 
limits based on sub-band), is the Alert symbol still required?

If it is not, what is the rationale for excluding it?

 Note that I have been operating under the assumption that the Alert sign is 
required, but I haven't had to make the decision on whether or not to apply the 
Alert sign since 2011 when the 2.4GHz band still required it, so I want to 
check & be sure.

Thanks,

Ed brings up some important advice. As an EMC (or compliance or product 
regulations) engineer, you'll need to strike a balance between meeting the 
letter of the law (with margin) versus the business needs of your company. 
While you can't break the law, you may find you'll often need to balance what 
you can achieve EMC-wise with product cost and schedule. For example, with 
radiated emissions (generally the toughest thing to meet), I would try to 
achieve at least a 6 dB margin below the limit across all frequencies. This 
would account for small test sample size and production differences in 
resulting emissions. Sometimes the right answer might be only a three dB 
margin. I would certainly not accept zero dB margin, however. You'll need to 
explain to management about production variances, etc. For high production 
runs, you may even consider running audit tests to ensure current products are 
still meeting the limit. The better EMC engineers will carefully weigh the 
legal requirements with the business needs and avoid being the "EMC Cop" - a 
good way to end your career before it starts.

Regarding Bob's advice on Learning and Teaching, my last 30 years were spent as

of the more junior engineers. Over the course of maybe a week or two, through 
the easy passes and the iterative fixes, that engineer got a continuous EMC 
fundamentals course (with the most practical hands-on possible). I loved doing 
this for two reasons; first, those junior engineers were usually fresh out of 
school, were bright and soaked up what I had to say. And second, explaining why 
a particular signal leaked, or why some shield didn't shield, made me 
constantly think about what I was doing and why I really did things that way. 
Because, every so often, one of those newbies made me improve my technique and 
clarify my own understanding.

A lot of those newbies moved on to other companies, but the ones who stayed

Not sure what exactly you want to specialize in, inside EMC.

However here is my advice:
1. KNOW EVERY RULE
2. CHANGE MINDSET
3. MAKE CONTACTS
and these two are REALLY important:
4. BECOME A TEACHER
5. LEARN, LEARN, LEARN; EXPERIMENT = become a Hands On Expert

KNOW EVERY RULE! To me, an EMC Engineer is a walking encyclopedia resource. 
Knows applicable rules and testing requirements. Knows every applicable NRTL 
[multiple ones] along with prices/estimation of ANY compliance testing [and 
TIME to test] For example an EMC Engineer will know the answer to the question, 
"What do we need in order to get such and such product sold in ??" Knows the 
labs to go to, how much to budget for testing cost, how much time, and how many 
number of units for testing. Will partner with Safety, because UL type labs 
destroy stuff.

CHANGE MINDSET! Think in terms of 'executive' and NOT 'engineer' Do NOT be a 
'fireman'. Be pre-emptive! KNOW every product your firm IS developing and 
probably WILL be developing. Always 'nose around' because EMC is usually, and 
catastrophically, left to the end of the Product Development cycle. You NEVER 
want to face the demand, "We're ready to go to Production, so fix it, but don't 
change anything!" Plan, plan, plan! Make certain there are enough 
representative samples. Product managers usually assume the units made for

"Appropriate for the intended use"



If applicable, the Regulation requires manufacturers to provide technical 
justification that the

requirements to provide a standby AND/OR off-mode AND/OR low energy mode, and 
in a

second stage an additional power management or similar function, are 
inappropriate for the

intended use of  the products (Annex II, point 4). The term "inappropriate for 
the intended

use" is however not further specified in the Regulation.



The onus to determine if a function is inappropriate for the intended use of 
the product is on

the manufacturer who is  best placed to assess the characteristics and 
functionality of the

product. It is admissible to claim the inappropriateness of the requirements 
for the intended

use of equipment, provided a technical justification is given in the technical 
documentation.

The Regulation does not prescribe any  additional requirements in respect of 
the technical

documentation to be provided by companies in this regard. Manufacturers should 
be able to

substantiate that they undertook reasonable steps and exercised due diligence 
in forming their

view on the inappropriateness of the requirements.

Subject: [PSES] ErP and Inappropriate for Intended Use



For ErP requirements, Commission Regulation 1275/2008 has these two points:



(c) Availability of off mode and/or standby mode Equipment shall, except where 
this is inappropriate for the intended use, provide off mode and/or standby 
mode, and/or another condition...



and



(d) Power management

When equipment is not providing the main function, or when other energy-using 
product(s) are not dependent on its functions, equipment shall, unless 
inappropriate for the intended use, offer a power management function, or a 
similar function...



Who determines and how does one justify "inappropriate for the intended use" 
option?



I have two cases. One involves a touch panel for user input. Marketing types 
say they cannot sell a touch panel that takes more than a second to respond. 
The second case involves a wireless (2.4 GHz) function.

Again the marketeers say that they cannot sell something that takes 20 seconds 
to wake from standby. So where or how does one justify that? And how does one 
get that justification "approved"?



Continuing, how does one write the DofC? Do you include the Directive/standard 
used to show compliance and add a statement that ErP is inappropriate? Or does 
one just leave the ErP Directive/standard out of the DofC completely?



In a variation of the wireless case, consider wireless audio. The receiver 
never knows when a user will send audio to the receiver. So the receiver must 
be on all the time to be able to play that incoming audio whenever the user 
requests it. But when the wireless is on, the unit cannot consume less than the 
proscribed 0.5W. Close, but no cigar. So in this case, can we say the unit is 
on all the time and we have a manual (means to go standby or off)? And that 
there is no automatic means to go standby or off because the radio is always 
listening for the incoming signal? Is that compliant with Phase 2?



This years development cycle seems to be all about gray places. We are not 
computers, servers, set top boxes or anything like that. But they are adding 
wireless to a bunch of stuff that never had it before so going to sleep has 
been vetoed by the marketeers. How does one make compliant product in these 
type of cases?



As always, looking forward to your creative replies. And as always, thanks in 
advance for your comments.

Scott

Does it require L and N to be connected directly together? If not, it's not a 
true common-mode test. But it's not clear what the point of the test is.

EN55024 refers to EN61000-4-5 requiring a test level of 1kV between L and N

The power supply failed the common mode tests of 2kV with damages. The power

Thank you for starting this discussion.

UN 38.3 is required by ICAO and IATA for air shipments worldwide. US DOT is 
working on aligning their requirements with this. UN 38.3 does not apply to 
train, truck, or boat transportation. Unless you make a rechargeable lithium 
battery that will never, ever be shipped by FedEX or UPS air, then this 
requirement applies. It is a physical test to ensure the battery does not come 
apart during shipment and create a hazard. It does not have any product 
performance requirements in it. China has added new twist, where manufacturer

There are packing and package labeling requirements as well for shipment of

Re: [PSES] Change to EMC regulation in South Korea on Audio Products?

2012-07-10 Thread Huang, Tim 
Exactly. We have a lot of audio products to do KC compliance in South-Korea.
For a non-wireless audio product, you have to do KN22 and KN24, KN60065 
(equivalent to EN55022 and EN55024) so as to obtain KC certification.
For a wireless(e.g wifi, BT)audio product, you have to do KN22, KN24, KN300328 
and KN301 489(equivalent to EN 300 328 and EN 301 489) and KN60065 so as to 
obtain KC certification.

Safety test depends on your product, if you proudct is powered by AC mains, you 
have to do safety, if you products are pwoered by AC adaptor, you don't have to 
do safety fo your audio product as long as the AC adaptor has its KC 
certification.

Noted that E-standby is required to audio prooduct, and KMEPS is required to AC 
adaptor. You have to get the energy efficiency test report and send it to your 
Korean distribotur for register purpose.

Subject: [PSES] Change to EMC regulation in South Korea on Audio Products?

Greetings from Berkeley,

I am writing to ask if any other manufactures have been ask to do additional 
EMC testing on audio products in South Korea.

The agent I use is saying that testing just a representative model will not be 
allowed and I will now need to test each model, which for me is audio frequency 
tuning changes and size of the wooden box. Neither of these change the EMC 
profile.   This is a analog amplifier with liner power supply.

"Until June 30th, EMC testing and Safety testing for this types of product 
(Audio Speaker) were done by KTC in Korea under MKE standard. However, from 
July 1st, EMC testing part shall be performed under KCC standard, and EMC part 
is regulated by KCC KN standard though safety was still regulated under MKE."

Comments?

Subject: [PSES] "Compliance Statement" in French Language

Dear Members,

If you know French, could you please provide me with "Compliance Statement" in 
French?  I work on a template, as shown below, for compliance statement per 
Industry Canada requirement.



Industry Canada (IC) Compliance Statement
This device complies with Industry Canada licence-exempt RSS standard(s).  
Operation is subject to the following two conditions: (1) this device may not 
cause interference, and (2) this device must accept any interference, including 
interference that may cause undesired operation of the device.
Under Industry Canada regulations, this radio transmitter may only operate 
using an antenna of a type and maximum (or lesser) gain approved for the 
transmitter by Industry Canada. To reduce potential radio interference to other 
users, the antenna type and its gain should be so chosen that the equivalent 
isotropically radiated power (e.i.r.p.) is not more than that necessary for 
successful communication.



Industrie Canada (IC) ???
Le présent appareil est conforme aux CNR d'Industrie Canada applicables aux 
appareils radio exempts de licence. L'exploitation est autorisée aux deux 
conditions suivantes : (1) l'appareil ne doit pas produire de brouillage, et 
(2) l'utilisateur de l'appareil doit accepter tout brouillage radioélectrique 
subi, même si le brouillage est susceptible d'en compromettre le fonctionnement.
Conformément à la réglementation d'Industrie Canada, le présent émetteur radio 
peut fonctionner avec une antenne d'un type et d'un gain maximal (ou inférieur) 
approuvé pour l'émetteur par Industrie Canada. Dans le but de réduire les 
risques de brouillage radioélectrique à l'intention des autres utilisateurs, il 
faut choisir le type d'antenne et son gain de sorte que la puissance isotrope 
rayonnée équivalente (p.i.r.e.) ne dépasse pas l'intensité nécessaire à 
l'établissement d'une communication satisfaisante.








Through online translation, I found "avis de conformité" is for "Notice of 
Compliance".  Notice of Compliance seems applying to the second paragraph.

Thank you very much and look forward to hearing from you.

Best regards,
Grace Lin

We have an IEC 60065 device under CB evaluation.  The power adapter's CB

Re: [PSES] FCC requirements for Inductive Chargers

2012-01-23 Thread Huang, Tim 


The FCC will approve handsets that are designed with batteries that can be 
charged wirelessly through their battery covers, only if the implementation is 
in accordance with the Wireless Power Transfer Interface Definition and 
Protocol (WPTIDP) requirements established by the Wireless Power Consortium 
(WPC standard).The handset wireless battery charging cover design should not 
deviate from this standard; it must include the operating frequencies, 
receiving coil design, and communication requirements of the standard. 
Furthermore, the charging hardware must be incorporated as an integral part of 
the battery cover, which is supplied by the manufacturer, or which can be 
acquired as an optional accessory for a specific handset model from the 
manufacturer.

If your handset wireless battery charging cover meets the requirements in the 
WPC standard, and if it is tested in accordance with the FCC's procedure 
described in KDB 
648474-D03-Handset-Wireless-Battery-Chargers-v01r01,
 a PBA is not required for TCB review and approval.

If your handset wireless charging battery cover utilizes other wireless 
protocols, you should submit a KDB inquiry to the FCC to confirm the test 
requirements first, and to avoid issues during the equipment certification 
process.

Today a colleague asked me a question as to why do we need NRTL certification 
such as UL or CSA on any product in the US. I thought this was a good and 
logical question and the way I answered it was that to the best of my

You probably fall under PSE circle Mark depending on the exact nature of your
