SIS: Standards by Committee

SIS Committees Don't Like Plain English. Their work is Peppered with High-Tech Buzzwords, Abbreviations and Acronyms That Make These Documents Harder to Read and Hence Less Valuable

By Bela Liptak

We all know the saying that the "camel is a horse designed by committee." Today's safety instrumented system (SIS) standard (ANSI/ISA 84.00.01 (2004), which is a relaxed version of IEC 61508/61511 (1996), is not a camel yet, only a camel baby. It can still be trained, but training needs trainers! Before explaining why I say this, let us look at what a safety integrity level (SIL) is.
