RE: CE (LVD) for Fruit Juicers

2002-06-20 Thread info

Hi Robert

This type of product would be covered by EN 60335-2-14, Particular
requirements for kitchen machines.  The scope includes citrus fruit
squeezers and centrifugal juicers.

Technically, the machinery Directive does apply since it meets the
definition of a machine, assuming that it is not excluded by article 1(5),
that is a risk assessment shows that the risks are not mainly of electrical
origin.  However in the UK, I do remember a DTI document which was issued
soon after the MD was released that said that products which have
traditionally fallen within the scope of the LVD in the past may continue
to do so.  I don't know if this advice has been superceded or forgotten or
whether it still applies since domestic electrical appliances within the
scope of EN 60335 have traditionally been in the scope of the LVD.

In practical terms, the main difference in the application of the LVD and
MD is the requirements for the technical file.  EN 60335-1 states
(Introduction) that the essential requirements of the LVD, MD and CPD are
covered by the standard (Noise and vibration???)

This and more information can be found in the European Commission DGIII
Guidelines on the application of council Directive 73/23/EEC.

I hope this helps.

Hi Group,

Looking through the OJEC LVD Standards list, I could not find under EN
60335 and its many parts a particular part that covered a juicer.

Does anyone know which particular part of this standard this product falls
under?

Also, not having seen this device, if it has blades like a blender, will
the Machinery Directive also be applicable?

Thanks for sharing your knowledge.

Re: Safety of microwave ovens

2002-01-15 Thread info

Ravinder

The IEC standard for microwave ovens is IEC 60335-2-25, this allows a
maximum leakage of 50W/m2 at 50mm or more from the external surface of the
microwave oven.  I tested a few of these a few years ago and found levels
well below the above limit even at closer than 50mm.  I am sure that the
models I tested will have been superceded a long time ago, this cannot be
applied to any specific samples available now.  The manufacturers may be
able to give you some idea of measurements.

Re: CE-mark compliance

2001-11-16 Thread info

John

We often come across large systems or machines where we ask the
manufacturer for certification details for the components, they sometimes
are unable to get much information from their suppliers, a common example
is for transformers where it is unlikely that they have been tested, except
as an end of line production test and are only supplied with a DOC.  We do
not accept these but are always asked.

I am sorry to hear that you are leaving this forum.  My feeling is that
your input was extremely useful and it will be missed (where do you get the
time to do the research, or is it all in your head).  It is particularly
useful to have somebody on standards committees to show us all how it
works.

Re: CE-mark compliance

2001-11-15 Thread info

Look in the archives of this discussion forum and you will see instances of
occassions where no testing has been conducted.  Test houses generally do
not accept a Declaration of Conformity for any product unless further proof
is available in the form of acceptable test results (from a 3rd party
laboratory or approved in-house laboratory).  This is not because they want
more testing and more money but because it is well known that the CE
marking process is abused by a large number of companies to different
degrees.  It is not uncommon for products to have a CE label attached but
no documentation at all and these products are frequently found to be
unsafe or to not comply with the EMC Directive.  Some companies do the
minimum possible i.e. make a quick assessment (not necessarily by a
knowledgable person) and write a Declaration of conformity, other companies
will do more in house testing, for example, hi-pot, leakage current and
earth bond.  Some companies employ safety engineers to perform testing and
others use external test houses.  For EMC it is more likely that nothing
has been done as a large number of companies know that they will only get
caught if their equipment is causing serious interference.

There is a sliding scale of testing that companies do, at one end nothing
is done, costs are low and risks are high, at the other end full third
party testing is conducted therefore costs are high but risks are low.  It
is up to buyers to decide where they want their end product to lie on that
scale and to buy from companies that are at a similar position or better.
They should request documentation to ensure that the equipment is suitably
assessed to that level of risk.

Some years ago before most of us knew what EMC meant, I came across a
company that did not employ a safety engineer and did not use a test lab at
all since it was cheaper to employ a lawyer with the knowledge to get them
off any charges if their equipment was found to be unsafe!

My advice, decide on your level of risk and choose your suppliers
carefully.

Hi all,

Do all manufactures fulfill the EU-directives with testing in their own
facilities or by an independent test lab? I guess the answer must be No.

From my time working in a test lab, my experience is that big companies
like
Alcatel, Siemens and so on, do the required testing according to relevant
requirements. I also got the feeling that small companies (I do not
generalize) where a bit laid-back and often put the CE-mark into the
products without any tests or with a very limited test process.

Should a system builder trust a Declaration of Conformity from a big
manufacturer, without asking for test reports in order to verify compliance
with relevant directives ? Would you sleep well at night,  if you only
trusted the CE-mark 100% and build a large broadband telecom system only
based on the CE-mark without any further documentation?

What is your opinion?

Best regards
Amund Westin, Oslo/Norway

Re: Applying the appropriate ENs

2001-09-27 Thread info

You do not make it clear as to what Directive you are referring to.  I can
respond regarding safety and the LVD.  The requirements under the LVD are
that equipment must be safe and complying with the principle elements of
the safety objectives of Annex I and that they should be constructed in
accordance with good engineering practise.  If the product complies with
the safety provisions of harmonized standards (listed in the OJ) then in
general it shall be considered to be safe.

The Directive does not say that products not complying with standards are
unsafe, and it does not directly specify which standard should be used for
a particular product (this is only obtained from the scope of the standard
in the OJ).  Therefore you can apply any requirements you like including
those of a 'non-appropriate' standard as long as the product is safe in the
situation that it being used.  If you use an inappropriate standard and the
product is found to be unsafe, you will be liable! - particularly if using
the appropriate sandard would have made the product safe.

Using the example below the options are:
   Retest to the appropriate standard for audio/video (Much of the testing
   will already be covered by the testing to the primary use standard),
   then list the new standard on the DOC.
   Make the judgement that there are no additional hazards associated with
   the secondary use and that compliance with the standard already used is
   sufficient, do not list the new standard as it has not been used.
   If your product is certified with an agency and the secondary use will
   also require certification, I expect there will be no choice but to use
   the new standard

I hope this helps.

Assume a product is primarily intended for a particular use (example: CCTV
for surveillance use) and the appropriate ENs are applied for that intended
use and a Declaration of Conformity is issued listing the applied standard.
Now assume that the product is marketed and sold for a secondary intended
use (example: professional audio/video) where the same essential
requirements apply but other ENs exist for that application. Is it legally
required to also apply the other ENs and list them on the Declaration?

Re: Low voltage exclusions for railways

2001-09-07 Thread info

Dear Nick

I once asked the LVD section of the Department of Trade and Industry
(Current contact - Chris Parish) this question, and the reply was that the
Shipping, aircraft and rail industries have their own (international?)
requirements and compliance should be against these requirements, they
could not tell me what the requirements were.

You can read this statement in two ways - one is that the above
requirements must apply.

The other: The wording states '...which complies with...', therefore my
question is, if the equipment does not comply with those safety provisions
can the LVD be used?  My assumption is NO.

I suggest talk to someone in the Rail industry.

international bodies in which the member States participate.

Specifically with reference to railways, does anyone know what what
this actually means in practice?

RE: Manufacturing Hipot Testing

2001-08-23 Thread info

Just a viewpoint from one of those commercial test houses.

In Europe the requirements of the Low Voltage Directive are that a product
must be safe, be constructed in accordance with good engineering practice
and comply with the principal elements of the safety objectives detailed.
It does not say that a product must conform to any standard, it does
however say that a product complying with a harmonised standard will be
deemed to comply with the safety provisions of the Directive.  Therefore
the law in Europe has no requirements for any production line hipot or
other testing provided you can show evidence that you have done all that is
necessary to show the product is safe.  Under the legal requirements it is
possible to deviate from any production line testing detailed in the
standards whether it is in an informative or normative or any other type of
Annex.

In practise it is difficult to imagine any way of ensuring an electrical
product is safe without some form of end of line testing.  Many test houses
operate certification schemes which give additional confidence to buyers
that a product is safe (or whatever other thing the marks are perceived to
show by the buyer).  Most test marks are private marks belonging to a
company, there is one exception and that is the German GS mark.  This is a
Government mark and forms part of the German Safety Law, it is not (and
never has been) Mandatory, the mark is issued by the TUVs and their
appropriate logo will appear alongside the GS mark.  This mark is well
established in Germany and other parts of Europe.

Regarding other issues brought up on this subject, by choosing a test house
carefully, it should be possible to obtain virtually all international
certification necessary through one body, possibly by using the CB scheme
(which is not a true certification scheme).  This has cost and time
benefits and should simplify the process.

I expect I have just told you all what you already know, but I hope it
helps.
