Re: [PSES] Electrical Safety - Fundamental Standards and Concepts

Hi James:

 

Understanding the basic physics and rationale of the safety standards
requires reverse engineering of the requirements.  And an understanding of
the people (and their biases) that wrote the standard.  Very difficult.

 

And, the safety standards are not necessarily in agreement with each other.
For example, one would think that electric shock requirements are
independent of the type of equipment, but they are not.  (In my opinion, we
should have a safety standard that addresses electric shock rather than
equipment.)

 

60664-1 is largely based on research by Stimper.  60479 is largely based on
research by Biegelmeier.  60990 has a good bibliography, although some of
the references have been ignored.  

 

I would recommend the following sources:

 

"Electrical Product Compliance and Safety Engineering," by Steli
Loznen, Constantin Bolintineau, and Jan Swart.  ISBN 13: 978-1-63081-011-5.

Papers presented at the annual IEEE Product Safety Engineering
Society "International Symposium on Product Compliance Engineering," 2004 to
2022. 

Join one or more national committees addressing product safety
standards.  

IEC Technical Committee documents.

UL "Bulletins of Research."  No longer available from UL, but
may be in some technical libraries.

Articles by Charles Dalziel. 

Books by Dr. Vyto Babrauskas, Ph.D. (Dr. Fire.)

Product Safety Newsletter, Product Safety Engineering
Newsletter.

"Electrical Shock Safety Criteria," Proceedings of the First
International Symposium on Electrical Shock Safety Criteria

1st Edition - January 1, 1985.  Editors: J.E. Bridges, G.L. Ford, I.A.
Sherman.  eBook ISBN: 9781483162201

 

With regard to electrically-caused fire in 62368-1, the PIS requirements
come from 60065 and Ernst Storm (deceased).  The 15-watt requirement came
from me based on ignition tests.  

 

Thermal burns are not due to object temperature, but skin temperature.
Standards requirements are object temperature.  

 

Have fun!  Best wishes for the holiday season,

Rich

Subject: [PSES] Electrical Safety - Fundamental Standards and Concepts

 

Hello experts,

 

My goal is to put together a reading and reference list of fundamental
standards that help me understand the basic physics and rationale behind the
requirements in safety standards (mainly EN 62368-1, EN 61010-1, EN
60335-1).

 

I've been finding a lot of useful references from the Normative References
sections of these standards and from the IEC TR 62368-2 explanatory notes.

 

In your opinion, what standards should I add to this list to expand my
knowledge of electrical safety?

 

Thanks in advance

James

 

 

 

General Terminology

  IEC 60050 IEV "Electropedia" although this
is sometimes lacking

 

Electric shock

IEC 60664-1 "Insulation coordination for equipment within low voltage supply
systems - Part 1: Principles, requirements and tests"

IEC 60990-1 "Methods of measurement of touch current and protective
conductor current"

IEC 60479 series shock current on humans and livestock

IEC 61201 Touch voltage limits

 

Electrically caused fire

Power source classification in 62368-1 references IEC 60065 and IEC 60950-1.
But where did they derive their information from? What are the power levels
based on?

UL 94 and UL 1581 for material and cable flammability

 

Thermal Burn

Basic standards detailing risks of touch temperatures ISO 13732-1 and IEC
Guide 117

Other?

 

Radiation

IEC 62471 "Photobiological safety of lamps and lamp systems"

IEC 60065 for audio levels

Other?

 

Mechanical hazards

???

Hi Doug,

Great link, but sorry for my ignorance of UK governance. To be clear this was a 
committee approval, it still needs to be approved by full House of Commons and 
the House of Lords before it is law, is that correct?

Does it require Prime Minister's signature?

@ Lauren Crane thanks for getting this started. The proverb about teaching a 
man(person) to fish comes to mind. And yet I still asked questions.

My understanding is that the extension is purely so that there is not an 
expired standard listed in the OJ for the LVD – that’s all

There is no legal link between the dates in a standard and compliance with a 
Directive

A manufacturer is free to use whatever standards they wish for compliance with 
LVD and article 3.1(a) of the RED, but only Harmonised Standards currently 
listed in the OJ provide a Presumption of Conformity

[PSES] Electrical Safety - Fundamental Standards and Concepts

2022-12-07 Thread James Pawson (U3C)

My goal is to put together a reading and reference list of fundamental
standards that help me understand the basic physics and rationale behind the

sections of these standards and from the IEC TR 62368-2 explanatory notes.

 

In your opinion, what standards should I add to this list to expand my
knowledge of electrical safety?
