ELECTRICALLY INSULATIVE UNDERLAYMENT - HARDBOARD SPECIFICATIONS

Green Core S2S Insulative Hardboard draws on the strength of wood while eliminating many of wood's weaknesses. Fibers are extracted from raw wood, rewoven and bound under heat and pressure by lignin, a natural adhesive found in wood. The result is a durable, tough, board completely uniform with exceptional strength. Hardboard is a true wood product. It's simply been re-engineered to form a more versatile material with predictable properties. The absence of grain makes it equally strong in all directions, and can be easily sawn, routed, drilled or shaped.

TESTING AND CERTIFICATION

Each 40220 HSB or HSC Mat is thoroughly tested to ANSI ESD S20.20-2014 standards. Documentation is provided with each mat upon request (an additional fee may be incurred). Our testing  provides the following:

Test Method 1, conductivity: ANSI/ESD S 20.20-2014 (page four, table two) TR-53 Footwear / Flooring Section Compliance Verification utilizing methods partially incorporated into ANSI/ESD STM7.1-2013 and STM 97.1. NOTE: Passing is <1.0E09. Results shown for method 1: Matting and Ground Cord Electrical Resistance to Ground (average of 5 readings), Point to Point Electrical Resistance (average of 5 readings) and the Electrical Resistance of a Technician in heel straps with the matting and ground cord per STM 97.1 (average of 5 readings).

Test Method 2, charge generation: ANSI/ESD S 20.20-2014 (page four, table two) TR-53 Footwear / Flooring Section Product Qualification per STM 97.2. NOTE: Passing is <100 volts.

WARRANTY: These mats are warranted for LIFETIME Static Control Performance, LIFETIME topical wear performance and LIFETIME compliance to ANSI ESD S20.20-2014, DOD 4146.26-M* and NFPA 484-15* ESD Standards. The ground cords are warranted for one year. These mats support chair caster traffic nicely but they are NOT designed for continual substrate to mat chair caster traffic. This type of traffic may cause chipping to the edges of these mats. Edge chipping is NOT covered under the warranty. BE SURE to order your mat in a wide enough width and long enough length to avoid this issue. Remember: The chair should always stay on the mat. Use ONLY ElectraClean and water or ElectraMat to clean these mats. Other cleaning chemicals may leave an insulative residue and make the mats brittle. *Note: May require a resistor free ground cord for NFPA and DOD standards. NOTE: These mats are custom cut and built to order. They are a non-refundable item.
