Re: Product Safety Semantics

John, I can only try to relate safety with the extensive use of shall with ISO certification having gone through the lead auditor course nightmare. For ISO 9001, there's about 136 shalls listed. Get all your shalls right and you *will get* the certification. Miss a shall and you *will

Virtual Grounding (Earthing)

Dear All, I have been shown this innovative plug-in product which has a socket for use with any appliance. The product has a virtual grounding system and is used to provide a reliable grounding system to installations where the grounding cannot be relied upon. Has anyone come across a

US NEC and Canadian CEC

Dear All, Does anyone have a resource for a Rule of Thumb method for the following pertaining to permanently wired equipment in the US and Canada? I am looking for something that is to the point and without having to use the NEC/CEC. 1. Determine the ampacity of conductors anticipated in the

10 N force Test on Internal Components Prior to Overvoltage Tests

Dear All, For IEC 950/UL1950, there is a requirements that before measuring spacings, a 10 N force test is required on internal components. However, there is nothing under the UL/CSA 1950 Overvoltage Tests (for telecom interfaces connected to exposed plant) which requires a similar test

RE: Product Safety Semantics

I can't help making this innocuous comment. (English is not my major.) All I have to say is that Europeans are, as usually, more attached to purified English. Shall is stronger (more dictatorial or, if you want, directive) than must. -Original Message- From: John Juhasz

IEC950 vs. EN 60950

Daniel, IEC950 and EN60950 are technically the same standards. The EN is a copy of IEC 950 with some common modifications. If you have the EN standard, these modifications are marked with a vertical line in the margin. Pierre SELVA SMEE Actions Mesures - This message is coming from the

RE: IEC950 vs. EN 60950

When a country adopts IEC950, it is sometimes necessary for that country to introduce national deviations due to local laws or conditions. EN 60950 contains EU deviations from IEC 950. -- From: Biggs, Daniel (IndSys, GEFanuc, NA) [SMTP:bigg...@gemischova.ge.com]

RE: NSA

Richard, You may try different Tx/Rx antenna deployment as well: (1) Move two antennas from their original places. Say, rotate the line between two antennas for 90 degree. You have large enough OATS. (2) Move your Tx antenna a little bit far away from the turn table. The wavelength of 30 MHz

Re: Off Topic Maybe: Hydrogen Fuel Cells

The upshot is that fuel cells for home use will either not use hydrogen at all (e.g., methanol), or will use another hydrocarbon as the input fuel with an internal reformer to make hydrogen on the fly. Hydrogen will not be transported or stored in significant quantities, whether as a gas, a

IEC950 vs. EN 60950

To those LVD expertshow do IEC950 and EN 60950 differ? I understand one is an international standard and one is european but are they considered the same basic standard? DB ___ Daniel W. Biggs HW Development

RE: Product Safety Semantics

Many thanks to those who responded to my query about the use/meanings of the words 'shall' and 'must' in product safety standards. Must and shall appear to be interchangeable. UL1950 uses both (couldn't make up there minds?), but 'must' appears a lot in the Annexes. EN60950 (IEC950) uses

Re: Product Safety Semantics

John, For the international and European standards the two terms of concern are shall and should. If a requirement is specified with shall it is mandatory and the wrath of God or his lawyers will be visited upon you for ignoring it. If the requirement is specified with should it is a

Need RF Switch info

I am having no luck finding data on a 6 position RF coaxial switch. Switch was manufactured by Dynatech / U-Z . (PN# M6-433G38FT -- 6 pole-28Vdc - DC-18Ghz). Picked up several surplus (new) to replace patch panel in lab. Anyone have an address / phone / catalogue data showing control

EMC testing laboratories accreditation in Germany ?

I'm looking for German accreditation for my EMC laboratory and I'm interested to know who is the rellevant body in Germany ( similar to UKAS / NAMAS or NVLAP ). The situation it's little bit confusing for me now, after the massive privatization of many governamental bodies. Any reply will be

FW: NSA

If the problem is on the horizontals, I hope that you have accounted for the Mutual Impedance Correction Factors of Table G4 (CISPR 16-1:1993). Also, check and make sure that your 3 metre antenna factors are ok, no VSWR problems (put a 3 dB pad to check). Do also make sure that there is no
