This std has left me 'scratching my head'. Do not know what to do with it...
Seems to be a truncated and ad-hoc combo of UL508, ISO 9k, GR-CORE, Mil-Std, and CISPR. The scope says what is not included: "These requirements do not cover controls covered by end-product standards in which an electronic control investigation is specified.", does not clearly define the targeted equipment, and does not talk about software. But it is one of the standards listed by my gate-control box that I bought off ebay. Whatever. So what products are actually using this std ? luck, Brian From: [email protected] [mailto:[email protected]]On Behalf Of Jim Eichner Sent: Friday, July 20, 2007 11:14 AM To: [email protected] Subject: RE: Interlock Circuits Firmware/Silicon Controlled This thread has missed one major standard: UL991 "Standard for Tests for Safety-Related Controls Employing Solid-State Devices", which in the scenario presented would be needed ALONG WITH UL1998 for the software, and the right approvals on whatever electro-mechanical device ultimately opens or closes a circuit. The UL991 requirements are a mix of EMC immunity and environmental withstand, with FMEA used to determine what components/subsystems require testing. Jim Eichner, P.Eng.
