ESD Anti-Static Flooring Selection Guide

Conductive vs Dissipative

Parameter	Conductive	Dissipative
Resistance (EN 1081)	10⁴ – 10⁶ Ω	10⁶ – 10⁹ Ω
Discharge speed	Rapid drain	Controlled, slower
Typical use	Electronics production, explosive / flammable zones, operating theatres	Server rooms, labs, healthcare ESD zones, general electronics
Body voltage (IEC 61340-4-5)	≤ 100 V (extreme)	≤ 2 kV acceptable (EN 1815 antistatic)
Backing	Carbon-black conductive network + conductive adhesive	Static-dissipative compound + conductive adhesive

The Grounding System Is Mandatory

ESD vinyl is only compliant when the full system is installed. Three elements are non-negotiable:

Element	Role
Conductive adhesive	Bonds the sheet and carries charge from the floor into the grid (≈0.22–0.32 kg/m²)
Copper-strip grid	Laid under the floor in a perimeter + cross pattern, connected to earth ground
Proper earthing point	Certified earth connection per local electrical code; verified by post-install resistance test

⚠️ Without conductive adhesive + copper grid + earth, the floor is electrically isolated and fails compliance. Do not specify ESD flooring on a standard adhesive job.

Responsibility

Who Owns Which Part of the Grounding Path

A conductive floor is one component. The path is built by more than one trade — this is a division of work, not a performance guarantee.

Role	Normally responsible for	Record that proves it
Flooring contractor	Laying conductive adhesive at the stated spread rate; copper strip layout and overlap; bonding the strip to the earthing terminal	Installation record plus resistance readings, with instrument and test voltage noted
Electrical contractor	Earth busbar, earth electrode, earth resistance	Earth resistance test record
Client / designer	Position of earthing points, target limits, acceptance criteria	Design note or acceptance specification
Material supplier (us)	Conductive adhesive and copper strip specifications, installation instructions	TDS and this table

Reading out of spec — check in this order

Instrument and voltage

An ordinary multimeter at the wrong test voltage reports a number that means nothing. Check the meter, the probe spacing and the applied voltage before questioning the floor.

Continuity to earth

Measure strip-to-terminal, not only surface-to-surface. A floor that reads correctly against itself can still be isolated from earth.

Continuity of the adhesive film

Gaps and dry joints appear as isolated patches. Map where each reading was taken; a single reading does not represent a room.

What we answer for. The material specification and the installation instructions. We do not guarantee a site reading: the result at handover belongs to the whole path, and the parts above are built and signed by different parties.

Frequently Asked Questions

What is the difference between conductive and dissipative ESD flooring?

Conductive ESD flooring has a resistance of 10⁴–10⁶ Ω per EN 1081 and is used where electrostatic discharge must be rapidly drained — electronics manufacturing, explosive or flammable areas. Dissipative ESD flooring has 10⁶–10⁹ Ω and suits general electronics, server rooms, laboratories and healthcare ESD zones where slower, controlled discharge is preferred.

Does ESD flooring work without a grounding system?

No. An ESD vinyl performs as specified only when it is installed with conductive adhesive and a copper-strip grounding grid bonded to the building earth. Without that path the sheet is electrically isolated: charge has nowhere to go, the installation fails a resistance-to-earth test, and the floor cannot be counted as part of the protected area.

Which standard defines ESD resistance?

The flooring material is measured in the laboratory per EN 1081 (R1/R2 electrodes). On site, resistance to earth is measured per IEC 61340-4-1, and body voltage per IEC 61340-4-5. The control programme follows IEC 61340-5-1, which requires an installed floor below 1 × 10⁹ Ω, while antistatic behaviour per EN 1815 is considered acceptable at ≤ 2.0 kV.

Report-backed values are third-party tested (Intertek, SGS) and published on our Test Reports page. Other classifications are product-performance data supported by in-house laboratory testing and are available on request.
