re: Limited Power Source - Batteries

2007-09-16 Thread emc-p...@ieee.org
Hello Amund:


To determine whether a battery is a LPS, perform
the measurements specified in EN 60950-1.

A lead-acid battery will easily exceed both the
8-ampere criterion and the 100 VA criterion.

The ratings you quote, 12 volts and 12 ampere-
hours, already tell us the battery is not LPS.

If you put a fuse in series with the battery,
the circuits on the load side of the fuse can 
be LPS.  Choose the fuse in accordance with the
EN 60950-1 requirements.

The circuits from the battery to the fuse are 
not LPS and will need to be in a fire enclosure.

Limited Power Source - Batteries

2007-09-16 Thread emc-p...@ieee.org
Hi,

We have 2 pcs 12V/12Ah batteries (cuopled in series) placed in a cabinett as
backup power source. Cables and plastic pipes run through the cabinet. We
have been told to check if the batteries are LPS, because LPS is required
for our cabinet since is shall act as a fire enclosure.

How can we check that the batteries are LPS? The batteries are Rechargeable
Sealed Lead-Acid.

We are talking about compliance towards EN60950-1.


Best regards

RE: Test report requirements for C-Tick, VCCI, etc. certification

2007-09-16 Thread emc-p...@ieee.org
Alex,
 
With respect to Australia, Ron Pickard is pretty much correct.
 
Firstly, the EMC regulations in Australia place the responsibility for
compliance with the local manufacturer of a device or the importer of the
device.  Australian product compliance regulations, including those for EMC,
are based upon the local manufacturer or importer signing a Declaration of
Conformity.  The only way the local manufacturer or importer may delegate
that responsibility is to appoint and agent by written agreement as
described in the ACMA web page at the following link: 
http://www.acma.gov.au/WEB/STANDARD/pc=PC_2067 
 
A product Compliance Folder must be established and must include product
information and test reports as detailed by the EMC regulations.  For an ITE
device the test report would need to state compliance with either AS/NZS CISPR
22 or CISPR 22 (to 240V) or EN 55022.  The device should comply with Class B
limits unless it can be sufficiently justified that the device will not
normally be installed/used within 10 metres or a broadcast receiver (i.e. in a
domestic environment).
 
One major correction to the advice from Ron is that the test report can be
from any reputable test house HOWEVER, having said that, the best way to
minimise the risk/liabilities and maximise the chances of a successful audit
by the ACMA (ACMA conduct random audits of organization's Compliance Folders)
is to ensure that, for EMC, any test report included in a product Compliance
Folder be from a test house that is accredited by an accrediting organization
with whom NATA (Australian accrediting body) has a MRA (Mutual Recognition
Agreement).
 
The 4 basic rules of product compliance in Australia are:

*   satisfy yourself the product complies with the requirements;
*   establish a product Compliance Folder and include all documentation 
required
by the regulations and used to satisfy yourself and demonstrate the product
complies;
*   sign a Declaration of Conformity (DoC); and
*   label the product with the A-Tick or C-Tick as appropriate and the
supplier's registered identify (usually the Supplier Code Number issued by the
ACMA to the supplier of the product [i.e. local manufacturer or importer])

Alex,

 

For Australia, emissions testing to ITE products needs to be performed against
AZ/NZS CISPR 22 (Australian  New Zealand national standard), which means that
if an Australian compliance folder is audited and contains a CISPR 22 based
test report, it may be rejected for two reasons, [1] when the then ACA started
accepting CISPR 22 reports, but required testing be performed at 240V line
voltage (testing to FCC15B requires testing at 120V and EN55022 requires 230V)
and [2]testing needs to be performed at a NATA accredited test lab if a lab
quality system MRA is not in place. I believe these are still requirements
(someone on the list please verify that). Please note that C-tick approval is
a self-declaration scheme managed by the ACMA, but a valid SDofC can only be
completed by a registered company in Australia.

 

As for VCCI, to claim VCCI compliance, your company must first become a VCCI
member. Otherwise, VCCI compliance cannot be claimed, but I believe EMC
compliance in Japan to be voluntary otherwise.

 

And, see below for my short answers to your questions.

 

I hope this was hopeful.

Ron Pickard

Hi,

 

I work for an equipment manufacturer. Initially, we had a product tested to
FCC Part 15 and EN55022, EN55024. Subsequently we needed C-Tick and VCCI
