ESD 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 % relative humidity |
| 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) |
| Measuring device for measuring body voltage generation | Walking Test Kit WT 5000 (Warmbier) or comparable |
IMPORTANT
ESD footwear requirements
The ESD shoes used in the EPA must have a resistance of < 5 MOhm according to IEC 61340-4-3 at climate class 1 (12 % relative humidity and +23 °C). In order to achieve charges of < 30 volts of human body charge during the walking test (at 12 % relative humidity and +23 °C), we recommend using the following ESD shoes: Weeger ESD clog, art. 48512-30, www.schuh-weeger.de.
Note: Measurement results can be affected by ESD clothing, ambient conditions, measurement equipment, cleanliness of the floor and the test personnel.

Note: Times are approximate and will be affected by changing ambient conditions, particularly temperature and relative humidity.
Consumption
| Layer | Product | Consumption |
| Primer | Sikafloor®-161 HC | 1–2 × 0.3–0.5 kg/m² |
| Wearing layer | Sikafloor® Conductive Set 1 × Sikafloor®-2350 ESD filled with 20 % Quartz sand (0.1–0.3 mm) | 1 earthing point per 200–300 m², minimum 2 per room. 1.5–2.5 kg/m² |
Note: With thinner layers, the chemical and mechanical resistance and the flow properties can be reduced.
APPLICATION
ESD CONDUCTIVITY MEASUREMENTS
Recommended number of conductivity measurements is specified in the following table:
| Ready applied area | Number of measurements |
| < 10 m² | 6 |
| ≥ 10 m² and < 100 m² | 10 to 20 |
| ≥ 100 m² and < 1000 m² | 50 |
| ≥ 1000 m² and < 5000 m² | 100 |
If the measurements yield values that are outside of the agreed specification, follow these steps:
- Carry out one additional measurement within a radius of approximately 30 cm around the original measuring point.
If the value of the new measurement meets the agreed specification, the original measurement can be disregarded.
If the value of the new measurement does not meet the agreed specification, repeat the measurement described above until the fulfilment of the requirements have been verified.
If the requirements cannot be verified, contact Sika Technical Services.
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.
