The Desco 74329 Statshield Smock, Grey Jacket with Convertible Sleeves, Size 6XL is designed to be antistatic, low tribocharging, and it creates a Faraday cage around the torso and arms of the wearer to protect ESD susceptible items from electrostatic fields generated by clothing on the operator's clothing. Static control garments are intended to attenuate electrostatic fields that may be present on personnel clothing. Statshield Smocks meet the requirement for Groundable Static Control Garment System per ANSI/ESD S20.20 required limit of < 3.5 x 10⁷ ohm Rtg tested per ANSI/ESD STM2.1 and ESD TR53 (23° ± 1° C, 12% ± 3% RH, and 50% ± 5% RH). The 74329 is constructed of a lightweight dissipative material which is made from texturized polyester and a minimum of 9% carbon nylon monofilament. The conductive nylon fibers are woven in a chain-link design throughout the material, providing continuous and consistent charge dissipation. All of the seams in Statshield smocks are designed to maintain electrical continuity from panel to panel and from sleeve to sleeve in accordance with the ESD Association Garment Standard, ESD-STM2.1.
