If you are an industrial robot user in North America (Canada and the USA primarily), you know ANSI/RIA R15.06 and CSA Z434. Did you know that ANSI has adopted the ISO robot safety standard? Learn more here…Read More
The EC Machinery Working Group announces the extension of the mandatory implementation date for EN ISO 13849 – 1:2008.Read More
In recent posts I’ve been discussing the changes in the use of EN 954 – 1, Safety of Machinery – Safety Related Parts of Control Systems. Part 1: General Principles for Design. The EU originally announced that this standard was to be withdrawn on 31-Dec-09, being replaced by EN ISO 13849 – 1. As you may know, there are significant differences in these two standards.

I get a lot of calls and emails asking about emergency stops. This is one of those deceptively simple concepts that has managed to get very complicated over time. Not every machine needs or can benefit from an emergency stop. In some cases, it may lead to an unreasonable expectation of safety from the user, which can lead to injury if they don’t understand the hazards involved. Some product-specific standardsRead More
At the recent PSES Symposium, I attended a couple of interesting workshops on EMC and Functional Safety. One was called “Workshop on EMC & Functional Safety” presented by Keith Armstrong, Bill Radasky and Jacques Delaballe. The other was a paper presentation called “Why Conventional EMC Testing is Insufficient for Functional Safety” presented by Keith Armstrong.
For readers who are new to the idea of Functional Safety, this field dealsRead More
