One of the most frequent questions engineers ask before inspecting Raised Floor Signal Reference Grid (SRG) & ESD Grounding Test is: "Which standard should I cite on the certificate, and where do the pass/fail limits come from?" This reference guide maps IEEE 1100 (Emerald Book) to national regulatory adoptions and provides the complete standard annex tables.
1. National & Regional Standard Equivalence Matrix

| Turkey (TR · Türkçe) | IEEE 1100 / TS EN 50310 / ANSI-ESD S20.20 |
| Germany / DACH (DE · Deutsch) | DIN EN 50310 / DIN EN 61340-5-1 / IEEE 1100 |
| France (FR · Français) | NF EN 50310 / NF EN 61340-5-1 / IEEE 1100 |
| Spain (ES · Español) | UNE-EN 50310 / UNE-EN 61340-5-1 / IEEE 1100 |
| Italy (IT · Italiano) | CEI EN 50310 / CEI EN 61340-5-1 / IEEE 1100 |
| Gulf / Middle East (AR · العربية) | IEEE 1100 (Emerald Book) / SASO / DEWA / ADDC |
2. Normative Acceptance Criteria & Mathematical Basis
ANSI/TIA-607-D requires <= 1 Ohm between bonded points; the point-to-point grid target below 0.1 Ohm is a commissioning convention. ESD floor bands come from ANSI/ESD S20.20 measured to STM7.1.
R_ESD_floor: 1.0 x 10^6 Ohm <= R_floor <= 1.0 x 10^9 Ohm (Static Dissipative) — ESD flooring resistance to ground per ANSI/ESD S20.20; walking body voltage must stay < 100 V (STM97.2).

ANSI/ESD S20.20 & ANSI/TIA-607-D Grounding & ESD Flooring Acceptance Matrix (ANSI/ESD S20.20-2021 & ANSI/TIA-607-D)
| Test Parameter | Test Method | Acceptance Range / Limit |
|---|---|---|
| Rack / Enclosure to Rack Ground Busbar (RGB) | 4-wire micro-ohmmeter | <= 1000 mOhm (1.0 Ohm) per ANSI/TIA-607-D (<= 100 mOhm typical) |
| SRG Node-to-Node DC Resistance | 4-wire micro-ohmmeter | <= 100 mOhm (0.1 Ohm) per IEEE 1100 commissioning convention |
| Flooring System Resistance to Ground | ANSI/ESD STM7.1 (100 V DC) | 1.0E6 to 1.0E9 Ohm (Static Dissipative) | < 1.0E6 Ohm (Conductive) |
| Personnel Walking Body Voltage Generation | ANSI/ESD STM97.2 | < 100 V peak |
