TESTING AND
CERTIFICATION
Each 40220 HSB or
HSC Mat is thoroughly tested to ANSI ESD
S20.20-2021 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 20.20-2021 (page six,
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 20.20-2021 (page
six, 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 S20.20-2021 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.
