ESD Data-Sheet Claims at a Glance
An ESD flooring data sheet may report floor resistance, walking body voltage and compliance with a named standard. Those statements describe different aspects of performance. Before using them to select or qualify a system, establish what was tested, with which footwear and under what conditions.
| Data-sheet statement | What it does and does not establish |
|---|---|
| Resistance range | Describes the product under the method and conditions the sheet names. Check the cited edition against the current ANSI/ESD STM7.1-2020 and ASTM F150-25. |
| Conformance or design-intent statement | A supplier assertion about a standard. It supplies no measured result for your footwear and flooring combination. |
| List of test methods | Names the documents behind a claim but gives no measured value or limit (methods without results). |
| Under-15 V body voltage | Applies to the footwear condition stated on the sheet, not to ordinary shoes or every footwear type (which footwear is covered). |
| Charge-decay time | A different quantity from walking body voltage; it does not replace an ANSI/ESD STM97.2-2016 result. |
| Personnel-grounding qualification | ANSI/ESD S20.20-2021 requires both system resistance below 1.0 × 109 ohms (ANSI/ESD STM97.1-2025) and peak body voltage below 100 volts for each footwear and flooring combination (qualification guide). |
Craftsman Concrete provides project-specific testing and closeout documentation to support the facility’s ANSI/ESD S20.20-2021 program and document testing under the applicable ANSI/ESD STM methods. When specified, the package includes selected-system product data, floor-resistance reports, mapped readings, test conditions, equipment records and pass/fail results against the project’s acceptance criteria.
STM97.1-2025 system-resistance and STM97.2-2016 walking-body-voltage reports are included when those tests are assigned. Corrective-work and retest records connect the original findings to their final disposition.
What Each Data-Sheet Claim Reports
Resistance figures depend on the named method and conditions
The supplier sheets reviewed here describe resistance differently:
| Product | Resistance statement on the sheet | Test method named on the sheet |
|---|---|---|
| PIP 200 ESD Conductive UR | Designed to impart electrical resistance readings below 1 million ohms | ANSI/ESD STM 7.1 and ASTM F-150 |
| Sikafloor-200 ESD, Sika | Static-dissipative range of 1.0 × 106 to 1.0 × 109 ohms | ANSI S7.1 / ASTM F150, as written on the sheet |
| RESUFLOR SCT, Sherwin-Williams | Surface resistance, point-to-point and point-to-ground, of 1 × 105 to 1 × 109 ohms, with results based on conditions at 77 °F (25 °C) | ANSI/ESD STM 7.1-2013 |
The table preserves the suppliers’ method names and editions. The linked guides explain the methods; they do not change which edition the supplier cited.
These figures apply to the products and conditions identified on the sheets. They do not establish identical performance under other conditions.
Conformance, design intent and method lists are different assertions
The selected sheets also describe their relationship to standards differently:
- Sikafloor-200 ESD: states that it conforms to ANSI S20.20-2021.
- Stonkote ESD, Stonhard: describes the coating as specifically designed to comply with the ANSI/ESD S20.20 specification, without identifying an edition.
- PIP 170 ESD SR: states that it meets or exceeds specification under named editions of STM7.1, STM97.1, STM97.2 and S6.1, without supplying measured values in that statement.
A list of test methods without results needs supporting evidence before it can establish measured performance.
Charge-decay time is different from walking body voltage
The PIP 100 ESD HB sheet states that the coating dissipates a 5,000-volt charge to zero in less than 0.1 seconds. It places that figure after its body-voltage statement without identifying a test method or configuration for the decay figure.
Charge-decay time and voltage generated on a person walking in footwear describe different quantities. One cannot substitute for the other.
What an under-15-volt body-voltage claim establishes
The footwear condition is part of the claim. The reviewed PIP 200 ESD Conductive UR and PIP 100 ESD HB sheets state body-voltage generation below 15 volts with conductive footwear. The Sikafloor-200 ESD and Sikafloor-2350 ESD NA sheets state under 15 volts with ESD-compliant footwear.
Those statements do not establish the same result with other footwear or ordinary shoes. The footwear assumptions behind supplier body-voltage claims explain what to check before applying a supplier’s result to the facility.
A floor-resistance range also cannot establish walking body voltage. The two measurements describe different properties, and body voltage depends on footwear, environmental conditions and movement.
Why Supplier Results May Differ From an Installed Floor
The tested assembly matters
STM7.1-2020 requires a qualification sample to include the flooring system’s components as they would be used in an installation (section 6.1.2.2.2). The qualification sample assembly therefore matters when assessing whether supplier evidence represents the specified system.
The method also explains that resistance-to-groundable-point measurements on qualification samples may differ from resistance-to-ground measurements on installed areas, particularly for materials such as floor finishes (section 1.3).
Request the resistance range and test voltage
STM7.1-2020’s informative Annex C advises specifying a resistance range at a defined test voltage rather than relying on the labels “conductive” or “dissipative.”
Request the system’s actual resistance properties and the conditions under which they were measured.
What to Request Before Relying on a Supplier’s Claim
Qualification evidence for the intended combination
Request documentation identifying the footwear and flooring tested, the methods, measured results, limits and environmental conditioning. Confirm that the evidence applies to the combination the facility will use.
S20.20-2021 permits product specification review, but a floor-resistance range or general footwear description does not establish both required system results. The footwear/flooring qualification guide explains the complete process, and the qualification-evidence guide addresses which records can support it.
The underlying floor-resistance report
Request the report behind the advertised resistance range, including measured values, test voltage, environmental conditions and the assembly tested. Compare it with the STM7.1 reporting requirements rather than relying on the data-sheet summary alone.

Frequently Asked Questions
Numerically, a result below 15 volts is below 100 volts. Whether it supports qualification depends on the footwear/flooring combination tested, the method, conditioning and supporting records. A headline value alone does not establish qualification of the facility’s combination, and the separate STM97.1 system-resistance requirement must also be met.
Only after identifying what each statement represents. Check the measurement configuration, method and edition, applied voltage, tested assembly and environmental conditions. A similar numerical range does not establish that the products were evaluated under the same conditions.
No. Charge-decay time describes how quickly an applied charge dissipates under the stated test conditions. Walking body voltage describes the voltage generated on a person moving in footwear on the floor. A charge-decay figure does not replace the required walking body-voltage measurement.
