Parasitic Coupling Between Unshielded Wire Loops

Hi All, I have just posted the third in a four part series of Technical Tidbits on shielded/unshielded loops. This article shows that for some uses, unshielded loops have less parasitic E-field coupling than shielded ones. In particular the unshielded loops appear better when used right up

UK - new Machinery Regulations

RE: UL 2054 testing for lithium batteries

Richard, If you want to prevent the battery pack from explosion/fire, compliance of those standards might not accomplish it for the time being. UL 2054, UL 1642 and UL 60950-1 were prepared and published before Sony's battery recall. All the standards are being revised to address the issue.

RE: UL 2054 testing for lithium batteries

Richard and Scott, Interestingly, some years ago I worked on a project involving a reaction calorimeter. One use (for some customers) was to test battery chemistries for just this type of runaway condition. The materials being tested were heated in a containment vessel until an exothermic

RE: UL 2054 testing for lithium batteries

Also be aware that the DENAN law in Japan has been amended so that some Lithium Ion Batteries are now regulated. Japan's Ministry of Economy, Trade and Industry (METI) has added Lithium batteries: into a list of regulated DENAN products. The new requirements for Lithium batteries will be

Hello everyone, Can anyone suggest a consultant in Europe who is plugged into the evolving Energy Using Products legislation machinery in the EU who would be able to keep us up to date on things they evolve?? We have resources here in the States and are involved in things developing here

Query on dealing with BSMI for EMC

Esteemed experienced colleagues, My company has a NVLAP-accredited EMC test laboratory in California. My product is ITE equipment (high value, low volume) and does not include telecom. My method of certification is usually the Declaration of Conformity. I understand that I can request my scope

OSHA / Safety Manual Requirements

Group, How do you/your company know if the instructions in your safety manual meet OSHA requirements? We are presently writing the User/Install/Maintenance manual for a new technology product and need to ensure the instructions meet OSHA requirements for the user/craftsman.

DO160E Cat Y testing

Can anyone forward the names and/or costs of doing DO160E CatY Radiated testing lease. I'm trying to collect budgetary numbers and facilities for a proposal. Perhaps an off line reply would be best. Thanks, Derek Walton L F Research - This message is from the IEEE Product Safety

Composite materials for 1 GHz testing

I have an out of the weather application want to build non-conductive tables. The testing will be for radiated immunity and emissions above 1 GHz. I know about the IEEE paper for 2001 and it has some good suggestions (polystyrene) and I found some more recent information in the EMC-PSTC

C-tick approvals

Greetings listmembers, I have a request to obtain C-Tick approvals for a computer platform we manufacture. I have been told that we need to have in-country representation in order to secure and maintain this approval. We don’t currently have offices there and don’t intend to work with a

RE: UL 2054 testing for lithium batteries

Does anybody have any insight into the changes that those standards are going to make in light of the incidents and recalls? If we can't rely on UL2054's requirements, and want to apply additional testing or requirements to UL2054 battery packs, then it would be helpful to know where that

Re: C-tick approvals

I just went through this and most domestic certification labs either have or work with reps down under. I explored finding an AU rep independently of a domestic lab and found that it's much easier and cheaper to use a domestic cert lab to file the paperwork. From: Michael Garretson

RE: C-tick approvals

Hi Michael, There are agents both in Australia and New Zealand that you can use for this. They would then issue the declaration, and hold the compliance folder, and you could mark your product with the C-Tick together with the agent’s supplier code. They will charge you an up front fee, and an

RE: Query on dealing with BSMI for EMC

Dear Jim, As far as I understand BSMI, BSMI only regulates standards (the S) and inspections (the I). For laboratory accreditation, you may need to contact the Taiwan Accreditation Foundation (TAF) or ILAC for MRA. Hope this may be of some help. Alain
