Last time I checked, there were still some EN standards that did not seem
to be available in searchable-PDF form from any source. Try ANSI

I think ANSI's EN collection is not complete. They do however sell all ISO

Probably will get a deluge of replies, but in case not, I think you are

EXTRACT: What is meant by a SILn system, subsystem or component?
A safety integrity level (SIL) is not the property of a system,
subsystem or component. However, the above phrase is often used to
Some thoughts. Assuming that this was a virus, the warning could be helpful
to some. While I agree with Robert comments in part, in fact a lot of the
viruses that exploit weaknesses in Microsoft Outlook use the sender's
address book. So you WILL get viruses from people you know or correspond
Depends a lot on the application, region and where on the equipment. For
example, for machinery, if the LEDs are part of the operator interface or

I suppose if there were a Directive for Decorative Items, (DDI), ugly
