Understanding ESD Smock Testing Procedures
To test ESD smocks , measurement of the fabric’s static dissipative properties is done on Ohm's scale and ensures that it is properly grounded. This is crucial to prevent the smock from acting as an isolated floating conductor. To start with, we look at how ESD smocks are defined by industry standards and why preventing them from becoming isolated conductors is so important. ESD Resistance Requirements for Smocks ESD garments are classified into three categories according to industry standards: Antistatic Clothing Groundable Antistatic Clothing Groundable Antistat Clothing Systems ESD Smock Requirements: For an item to be considered an ESD smock, it should have a surface resistivity of less than 1 x 10¹¹ ohms. Antistatic Clothing: Surface resistance is below 1 × 10^11 ohms when checked across the garment using the point-to-point method as shown in Figure 5 below. Place electrodes from the met...
