At the moment this is just a placeholder. Later I will post here about some of my experiences with UL1998 and the ETL certification process. For some reason there’s a dearth of useful information on the world wide web. I’ve not had luck finding information that is sufficient for someone new to the process to put rubber to the road, or even know where to start. The UL1998 document of course may be purchased, but it is far from sufficient for a beginner or even an experienced developer with no safety certification experience. It is a sparse document with no concrete examples of sufficient evidence for any requirement. It is, after all, a certification requirements document (and somewhat dated).
I will not be quoting from the UL1998 document. In fact I will not look at it while writing this post, but instead give an overview of what to expect to need for certification. I may also make some references to ISO 26262 (an automotive safety standard), mostly in the interest of highlighting cross-domain knowledge that is applicable for both UL1998 and ISO 26262.
