IEC 61850 Conformance Certification of IEC 61850 Core Documents with Ed2.0 About to End

Richard Schimmel (IEC 61850 Certification Manager at DNV ( former KEMA)) just reported a very crucial information at LinkedIn:

"IEC 61850 certification for Edition 2 will be phased out by the UCAiug. From January 2024 UCAiug will only allow new Edition 2 certificates after passing the Edition 2 with Amendment 1 (Ed2.1)!

If you want to certify IEC 61850 Edition 2, we (DNV) need to show the UCAiug that we received the purchase order before 1st January 2024."

Be aware that Edition 2.1 refers just to the yellow marked core parts of IEC 61850 (see IEC 61850 Tissue Database):

 

Note that EACH part has its own Edition numbering ... there is no IEC 61850 Edition x at all!

The Tissue Database provides the tissues posted, discussed, and solved of the previous editions for each part. This gives you the possibility to see which comments let to a new edition. Comments to Edition 2.1 of the core parts will finally lead to Edition 3.0 of these parts ... Edition 2.1 of the core parts will be valid for the next years ... this is my personal expectation.

Boeing's 737 MAX - A True But Unbelievable Story Told In A New Report

The final 245 page committee report (September 2020) on the problems with the Boeing 737 MAX tells stories that we (as engineers) could not believe! Or?

There are are many very crucial details that have been reported. You have to read the report on your own ...

Here are two excerpts that made me very sad:

"The story of the Boeing 737 MAX was never expected to be associated with catastrophe. It was supposed to be a story of American ingenuity and technological success—a modern, more fuelefficient airplane that had already become the manufacturing giant’s best-selling jet in its storied history prior to the first MAX crash ..." ... Obviously it was too easy to cheat ... in order to make more sales ... to earn more money, to get richer ... to ... what ever.

"... FAA delegated some certification activities to Boeing that it should have retained. In the case of the 737 MAX, in 2013, the FAA originally delegated 28 of 87 tasks to Boeing. However, this number rose to 79 of 91 activities by November 2016, four months prior to final certification of the 737 MAX aircraft."

Be aware that is very common in the industry to allow self-certification ... so, the results may be similar as with the 737 MAX ... non-conformity of a protection relay may lead to severe blackouts and ...  

One obvious reason for these behavior of humans these days could be found in 

"And for this cause God sendeth them a working of error, that they should believe a lie: that they all might be judged who believed not the truth, but had pleasure in unrighteousness."
