RE: UL standards for Automotive ESAs

[Chris Chileshe]

Thank you for the welcome and thank you to everyone who 
replied to my query on the subject.

Perhaps I should have mentioned that I have spent long hours 
in the past browsing the UL and associated websites for any 
such standard and have not had much success.

Patty Knudsen replied and wrote she believed there was
no UL standard for automotive ESA safety and I am inclined
to believe that is the case, unless anyone else out there 
knows better.   

I have been directed to the SAE website and must say it looks quite 
promising. The URL is http://www.sae.org/servlets/index

I thought I'd send an update to the list in case there was anyone
else interested in the subject or would beg to differ.

Best regards

- Chris

Subject: UL standards for Automotive ESAs



Hi all,

New subscriber here.

I have recently moved from designing variable speed drives
to automotive electronics and hence aiming for the 'e' as
opposed to the CE mark. As part of our drives release 
procedure, we were required to meet UL standards and 
used to test to UL 508C.

I have clearly established the other standards I need to be
designing to such as ISO-7637, ISO 10605, ISO-11452,
CISPR-25, CISPR-12 and CISPR-16, but I have been rather 
hard pushed to find a UL equivalent for automotive electronics
i.e. is there a UL safety standard for vehicle Electronic 
Sub-assemblies (ESA), the likes of engine management units
etc?

Would appreciate some advice.

Regards
