Testing kV RatingsFor a kV rating to be at all meaningful, the esd carpet must be tested under all pertinent environmental conditions.
- The voltage testing should be done at low relative humidity
- Multiple types of shoes should be worn by the people doing the testing
Othewise, you haven't tested the real-world environment under which the carpet will be used.
ESD Carpet Samples Must Be Washed Prior to Testing In order to properly evaluate a carpet's static protective qualities, it is critical that the ESD carpet sample be washed before testing.
After production, manufacturers often spray their carpets with an anti-stat. While these anti static carpets provide good initial test results, as soon as the anti-stat wears off--usually in a matter of several weeks to a few months--that same anti static carpet can become a significant generator of static. |
