It is a complex topic. Enjoy!

The additional questions arise from direct seismic action and the additional forces developed during such an event. It doesn't seem to me that the Euro Zone is particularly active from the seismic point of view and we've not run into this issue before but are doing our due diligence here to ensure that no stone is left unturned. The USGS Seismic history of the earth 1900-2014 website doesn't even include a reporting zone for Europe. So maybe this isn't an issue for the MD. :>) br, Pete Peter E Perkins, PE Principal Product Safety Engineer PO Box 23427 Tigard, ORe 97281-3427 503/452-1201 fone/fax [email protected] _ _ _ _ _ >From the MD Annex I 1.3.1. Risk of loss of stability Machinery and its components and fittings must be stable enough to avoid overturning, falling or uncontrolled movements during transportation, assembly, dismantling and any other action involving the machinery. If the shape of the machinery itself or its intended installation does not offer sufficient stability, appropriate means of anchorage must be incorporated and indicated in the instructions. I'd interpret this to apply to seismic stability if that could be a concern. -Dave -----Original Message----- From: Pete Perkins [mailto:[email protected]] Sent: Monday, November 24, 2014 4:37 PM To: [email protected] Subject: [PSES] Seismic requirements- Euro Machinery Directive ok group, I'm dealing with a large machine which, by design, seems top-heavy. The issue of stability in an active seismic environment has been raised. Are there any specific requirements or guidance in Euro standards pertaining to seismic stability? :>) br, Pete Peter E Perkins, PE Principal Product Safety Engineer PO Box 23427 Tigard, ORe 97281-3427 503/452-1201 fone/fax [email protected] - ---------------------------------------------------------------- This message is from the IEEE Product Safety Engineering Society emc-pstc discussion list.
