"Addition to 10816-3" 2012 for screw compressors and Roots blowers, seem to add a parameter B to monitor pulsations and such if I don't misread it. Any comments? Interesting that these additionals pop up and even more interesting that suppliers refer to them as acceptance criteria when having normal startup issues like alignment and such basics that trigger the normal 10816-3 but supposedly maybe not this addition. I see a new market for vibrometers tuned to your personal liking, and various interesting parameters. I can Real Soon do that :-). Just send a recipe and I can bake a cake, joking aside, these additions do tend to end up in a ISO standard sooner or later and it is maybe good but add to the problem what standard to follow when the normal case is that nothing is written in the purchase documents.

I worked inhouse. We developed our own acceptance standards for new machinery. 
We presented these standards to all venders that wanted our business before signing contracts. Our standards were usually stricter than they stated. Some venders walked away, most did not. Probably helped that we were a large international company.

Yes we wrote a compilation relating relevant standards for the joint paper industry group here many years ago SSG3030, it has been adapted by steel and mining industry here but still rarely found in the purchasing documents...
So having any requirements is fine just let me know what I should judge against when doing the survey.... I used to say, if you buy machinery use 10816-1 if you sell use 10816-3 maybe with the above addition or any other I don't know of, that is, where those are used. I think they eventually will harmonize everything and it will be total harmony?
