Tyvek® and Tychem® protective clothing meets the requirements of the DIN EN 1149-1 standard. N.B.: The antistatic properties of Tyvek® and Tychem® protective clothing depend on taking up moisture from the air. It is therefore essential to ensure that the relative humidity of the environment in which they are used is sufficiently high, as these products do not offer reliable antistatic protection if the relative humidity is below 25%. Please note that the antistatic treatment only means the clothing material can conduct a charge; the clothing must first be properly earthed for a controlled discharge to take place. This means that both the clothing and the wearer must be permanently earthed, taking care to ensure that the surface of the clothing which has been given antistatic treatment is earthed. DuPont has commissioned the Swiss Safety Institute (Basel) to carry out tests investigating the use of Tyvek® and Tychem® protective clothing in EX zones. The table on the left shows the situations in which clothing can safely be used (i.e. when the box is checked for both the zone and the explosion group).
