8900 Series: High-Performance Lightweight Plus Protection

The Lightweight Plus 8900 Series represents the next generation of ESD protective wear, offering enhanced durability and superior static dissipation. Engineered with a specialized 6mm rhomb warp-knit weave, these garments provide a robust “Faraday cage” effect that shields sensitive electronics from electrostatic charges while maintaining a professional, lightweight feel suitable for all-day wear.

Industry Applications

The 8900 Series is designed for advanced technical environments where high-reliability static control is non-negotiable:

High-Precision Electronics: Ideal for microchip handling, SMT lines, and advanced circuit board assembly.
Cleanroom-Adjacent Environments: The 97% Polyester construction minimizes linting, making it suitable for Class 10,000 (ISO 7) environments.
Automotive Electronics: Used in the production of sensitive ECU and sensor components.
Testing & Calibration: Provides a stable, static-free environment for sensitive measurement and diagnostic tasks.
Telecommunications: Protection for high-speed networking hardware and fiber optic equipment.

Performance & Compliance

Rigorous Standards: Fully compliant with ANSI/ESD S20.20-2014 and IEC 61340-5-1 for “Static Control Garments.”
Advanced Conductivity: Features a high-density 3% Carbon conductive grid that ensures consistent surface resistance between 10⁶ and 10⁷ Ohms.
Rapid Dissipation: Achieve a charge decay rate of 0.5 seconds per 1000 volts, ensuring static is neutralized almost instantly.

Enhanced Durability & Comfort

Warp-Knit Strength: The unique 6mm rhomb weave provides exceptional Tear Strength (1600g Warp) and Tensile Strength (100kg Warp), outperforming standard lightweight smocks in demanding industrial settings.
Breathable Design: At 3.54 oz per square yard, the 8900 series offers a “Plus” weight that is more durable than the 8812 line but still significantly more breathable than traditional heavy-duty cotton blends.
Low Friction Charging: Engineered to minimize friction-generated charges (triboelectric charging), staying below 1150 volts even during high-activity shifts.

Professional Customization

Secure Grounding: Equipped with 4mm Cuff Snaps (1 Socket, 1 Stud) for reliable integration with grounding wrist straps.
Style Options: Available in a variety of professional colors to facilitate department coding or brand alignment.
Precision Fit: Offered in a full range of sizes to ensure operator comfort and full coverage of street clothing.

Advanced Warp-Knit Construction

Unlike standard ESD fabrics, the 8900 Series utilizes a specialized 6mm rhomb warp-knit weave. This construction provides superior dimensional stability and a significantly higher strength-to-weight ratio. The result is a garment that resists snagging and tearing while maintaining a lightweight, breathable profile of 3.54 oz per square yard.

Integrated Conductive Grid

The fabric features a high-density 3% Carbon-suffused nylon grid woven directly into the polyester base. This permanent conductive network provides:

Surface Resistance: A consistent range of $10^6$ to $10^7$ Ohms, ensuring the garment remains safely within the dissipative range.
Charge Decay: Rapid neutralization of static, achieving a decay rate of 0.5 seconds per 1,000 volts.

Industrial Strength & Durability

Designed for the rigors of daily industrial use, the 8900 fabric boasts exceptional mechanical properties:

Tensile Strength: Reaches 100kg (Warp) and 54.3kg (Weft), ensuring the garment maintains its integrity under physical stress.
Tear Strength: High resistance to punctures and rips, tested at 1600g (Warp) and 1200g (Weft).
Low Friction Charging: Engineered to minimize triboelectric charging, keeping friction charges at or below 1150 volts.

Certified Compliance

Every garment in the 8900 Series is manufactured to meet or exceed the most stringent global ESD standards:

ANSI/ESD S20.20-2014: Standard for the Development of an Electrostatic Discharge Control Program.
IEC 61340-5-1: International standard for the protection of electronic devices from electrostatic phenomena.

Laundering & Maintenance Instructions

To maintain the electrical integrity and prolong the life of your 8900 Series ESD Jacket, proper laundering is critical. Standard industrial cleaning or harsh chemicals can break down the carbon-suffused fibers, compromising the garment’s ability to dissipate static.

Best Practices for ESD Longevity

Detergent: Use only non-ionic, liquid detergents. Avoid powders or detergents with added “brighteners” or softeners.
Temperature: Machine wash in Cold or Warm water (100°F / 38°C maximum).
Drying: Tumble dry on Low heat or hang dry. High heat can cause the synthetic fibers to shrink or become brittle.
Bleach & Softeners: NEVER use bleach, starch, or fabric softeners. These coatings will insulate the conductive fibers and render the ESD protection useless.

Expected Service Life

Most ANSI/ESD S20.20 certified smocks are rated for approximately 80 to 100 washes when following these guidelines.

Warning: Using a standard “industrial washing service” that utilizes high-heat drying or harsh chemicals may degrade the garment’s effectiveness in as little as one cycle.

Testing Recommendation

We recommend testing your garments periodically using a surface resistance meter to ensure they still meet your facility’s ESD safety requirements.

ANSI / ESD S20.20 Compliance

A certified “Static Control Garment” is a critical component of any ESD Protected Area (EPA). The 8900 Series is designed to meet the rigorous standards set by the ESD Association to prevent costly damage to sensitive electronic components.

Understanding the Standard

According to ANSI/ESD S20.20, a compliant garment must maintain a surface resistance of less than 1 x 10¹¹ Ohms when measured point-to-point.

Why the 8900 Series Complies:

Faraday Cage Effect: The integrated conductive grid (6mm x 5mm) acts as a shield, containing static charges generated by the wearer’s inner clothing and preventing them from reaching sensitive devices.
Point-to-Point Resistance: Rigorously tested to stay well within the 1 x 10¹¹ Ohm limit, typically measuring in the 10⁶ to 10⁸ range.
Reliable Grounding: When used with the integrated hip stud and cuff snaps, the jacket can serve as a primary grounding path for the wearer, meeting the requirements for Garment System testing.

Testing & Verification

We recommend using the ESD TR53 “Garments Section” test method for your periodic compliance audits. Regular testing ensures that laundering or wear-and-tear has not compromised the conductive path of the garment.

Compliance Note: To maintain your facility’s S20.20 certification, ensure all personnel are trained on the proper laundering of these jackets to prevent insulative build-up from standard detergents.
