The standards behind a static control floor
Twelve documents decide what your floor has to do. Most facilities only need two or three of them, and knowing which ones apply is most of the buying decision. Each is broken down below with its numbers and its source.
under 1.0 x 10^9ohmsANSI/ESD STM97.1
under 100voltsANSI/ESD STM97.2
2.5 x 10^4 to 1.0 x 10^6ohmsANSI/ESD STM7.1 / ASTM D257 (as cited on manufacturer TDS)
Every standard, and what it governs
