TECHNICAL BULLETIN TB-3042 Heavy Duty Cotton Poly ESD Smocks Made in the United States of America Installation and Maintenance in the garment are designed to maintain electrical continuity from panel to panel and from sleeve to sleeve in accordance with the ESD Association Garment Standard, ANSI/ESD STM2.1. The smocks include a snap socket on each cuff. Heavy Duty Cotton Poly ESD Smocks are available in Item Size Chest Sleeve 73505 Small 34 - 36 34 73506 Medium 38 - 40 34 - 3/8 73507 Large 42 - 44 35 73508 X Large 46 - 48 35 - 1/2 73509 2X Large 50 - 52 35 - 1/2 Instructions for use Figure 1. Desco Heavy Duty Cotton Poly ESD Smocks Follow these directions for proper installation and grounding of the Heavy Duty Cotton Poly ESD Smocks: Description Desco Heavy Duty Cotton Poly ESD Smocks is a Put on the garment, fastening all the press studs on 11 Static Control Garment with Rtg < 1 x10 ohms the front of the smock ensure no clothing is exposed meeting the required limits of ANSI/ESD S20.20 when outside of the smock.

Regular laundering of static control program. control garments according to the manufacturers recommendation is suggested to make sure conductive Garments can also be very important in field work, as fibers do not become contaminated and rendered the area may be an uncontrolled environment which insulative. After laundering, thorough rinsing of the can be very dry. garment will help eliminate the possible buildup of chemicals on the conductive fibers, which can cause Desco Heavy Duty Cotton Poly ESD Smocks are them to become insulative. Drying garments at high designed to be antistatic, low tribocharging and offer temperatures may degrade conductive fibers in fabrics protection to ESD sensitive items from electrostatic used to manufacture garments. (ESD TR20.20-2008 fields generated by clothing on the users body. section 5.3.13.6 Other Considerations) The Heavy Duty Cotton Poly ESD Smocks create a Faraday Cage around the torso of the wearer that shield ESD susceptible items from static charges generated on the wearers clothing. The Heavy Duty Cotton Poly ESD Smocks are constructed of a heavy weight cotton/poly blend with a minimum of 1% conductive fiber providing continuous and consistent charge dissipation.

Surface Resistance 9 of Fabric Rpp < 1 x 10 ohms per ANSI/ESD STM2.1 Static Decay Rate 5000 volts to 500 volts in less than 0.1 seconds, per FTMS-101C Compliance Verification Testing Panel to panel conductivity is essential and easy to test using our Digital Surface Resistance Meter Item 19290, by placing 5 pound electrodes on different panels. For additional information, refer to ANSI/ESD S20.20, ESD TR20.20, the ESD Association Garment Standard, ANSI/ESD STM2.1, and Compliance Verification ESD TR53. Maintenance For proper operation, ESD garments must be laundered periodically. Woolite works well. Liquid detergents are better than dry in that there is less caking and frictional wear. Launder garment in cool or warm water, tumble dry with low heat or hang dry. In terms of laundering the smocks by hand or with a washing machine, most prefer using a washing machine. This works well if using a standard house machine on gentle cycle. Industrial machines are fine if Pony (typically under 200 pound loads) machines are used. It is not recommended to launder these garments in heavy industrial laundry machines as it will lead to premature wear. Garments should be tumbled dry using low heat. DO NOT BLEACH. The conductive fibers are sensitive to heat and should not be exposed to laundering heat in excess of 120F. Use only non-ionic softeners and detergents when laundering. Under normal wearing and recommended washing conditions, Desco Heavy Duty Cotton Poly ESD Smocks will maintain their usefulness and effectiveness for a minimum of 50 washings.
