ECF MEASUREMENT CONDITIONS AND SPECIFICATIONS
All measurement values for the system stated in the System Data Sheet (except those referring to proof statements) were measured using the following equipment and ambient conditions:
| Condition or Equipment | Specification |
| Size of ESD-footwear | 42 (EU) (UK: 8; US: 8,5) |
| Test person weight | 90 kg |
| Ambient conditions | +23 °C and 50 % r.h. |
| Measuring device for measuring resistance to ground | Metriso 2000 or 3000 (Warmbier) or comparable |
| Surface resistance probe | Carbon Rubber electrode. Weight: 2.50 kg |
| Rubber pad hardness | Shore A (60 ±10) |
Measurement results during testing
Note: If values are lower or higher than required, carry out additional measurements about 30 cm around the point where the faulty readings are located. If the re-measured values are in accordance with the requirements, the total area is acceptable. If the requirements cannot be verified, contact Sika Technical Services.

Temperature | Minimum | Maximum |
+10 °C | ~17 hours | ~4 days |
+20 °C | ~9 hours | ~48 hours |
+30 °C | ~7 hours | ~24 hours |
Before applying Sikafloor®-262 AS N on Sikafloor®-220 W Conductive allow:
Temperature | Minimum | Maximum |
+10 °C | ~26 hours | ~7 days |
+20 °C | ~17 hours | ~5 days |
+30 °C | ~12 hours | ~4 days |
Note: Times are approximate and will be affected by changing ambient conditions, particularly temperature and relative humidity.
Applied Product Ready for Use

Note: Times apply when the last layer of the system has been applied. Times are affected by changing ambient conditions, particularly temperature and relative humidity.
Consumption
| Layer | Product | Consumption |
| Primer | Sikafloor®-150 Sikafloor®-151 Sikafloor®-156 Sikafloor®-161 | 1–2 × 0.3–0.5 kg/m² |
| Levelling | Sikafloor®-150 Sikafloor®-151 Sikafloor®-156 Sikafloor®-161 | Refer to the individual Product Data Sheet. |
| Conductive primer | Sikafloor®-220 W Conductive | 1 × 0.08–0.10 kg/m² |
| Earthing connection | Sikafloor® Conductive Set | 1 earthing point per approx. 200–300 m², min. 2 per room |
| Option 1: Conductive wearing layer | Sikafloor®-262 AS N Filled with Sikafloor® Filler-1 | Min. 2.25 kg Binder + 0.25 kg Sikafloor® Filler-1. Max. 2.0 kg Binder + 0.5 kg Sikafloor® Filler-1 |
| Option 2:Conductive wearing layer | Sikafloor®-262 AS N Filled with quartz sand F34 | Min. 2.25 kg Binder + 0.25 kg quartz sand F34 Max. 1.75 kg Binder + 0.75 kg quartz sand F34 |
The filling grade varies on the air temperature at application, lower temperatures require less filling.
Note: Consumption data is theoretical and does not allow for any additional material due to surface porosity, surface profile, variations in level, wastage or any other variations. Apply product to a test area to calculate the exact consumption for the specific substrate conditions and proposed application equipment.
APPLICATION
INSTALLATION OF EARTHING POINTS
Refer to Sika Method Statement: Sika Method Statement — Sikafloor® mixing and application
Number of earthing connections per room: Minimum of 2 earthing connections. The optimum number of earthing connections depends on the local conditions and must be specified on drawings or other contract documentation.
