2. Inside corners of cutouts for electrical outlets, sinks, etc.,
should have a minimum radius of 1/8" (3mm) and should
be filed smooth. This reduces the likelihood of stress
cracks.
3. All edges of laminate should be filed smooth with file
direction towards substrate to help prevent stress cracks
and to minimize chipping.
4. When nails or screws must be used, it is advisable to first
drill an oversized hole through the laminate. This
reduces the likelihood of stress cracks.
5. Micastat is intended for interior use only, and should not
be exposed to extreme humidity, continuous sunlight, or
temperatures above 275°F (135°C) for extended periods
of time.
6. Work surfaces must be grounded for proper static
dissipation.
For more information on the characteristics of nonindustrial
laminates related to end-user applications please refer to

LD 3-1995. The address for NEMA is:

Once installed, Micastat
must be grounded to ensure
proper charge dissipation. See below.
General Grounding Guidelines
1. When grounding Micastat
, it is essential to make
intimate contact with the conductive layer which is
directly below the dissipative, color layer. See the
diagram on page 1 showing the multi-layered
construction.
2. For proper and safe ESD protection, the grounding wire
must be tied directly to and at the same potential as the
facility power ground or “green wire” ground. A typical
“green wire” ground if properly wired is the screw of a
switch or outlet cover plate.
3. If power is to be used at the ESD protected workstation,
per ANSI/ESD S20.20 paragraph 5, a Ground Fault
Circuit Interrupter (GFCI) is recommended.
4. Test all workstation grounds for proper resistance to
ground. See Desco Technical Bulletin TB-2007 for a
complete discussion of grounds. For information on
instruments and procedures for the proper testing of
grounds we recommend that you contact ECOS
Electronics, 205 Harrison Street, Oak Park, IL 60304,
(708) 383-2505, Fax (708) 383-2137.

5. The selection of ground cords is intimately related to the
organization’s material handling procedures. It is
important for a user to be familiar with his/her own
organization’s grounding specifications and ESD
procedures prior to selecting ground cords. See
paragraph 2 in Cautions section of this Technical Bulletin.
Grounding Methods for Installed Sheet Goods
Desco offers two styles of ground systems that will ground
your static dissipative laminate worksurface: Item No. 14240
and 14246. These ground assembly kits are for use when
the laminate sheet is installed on a wooden workbench top.
1. Item No. 14240, our Laminate Grounding System
contains all the items needed to properly ground a
permanently installed Micastat
top. This includes a 10
foot grounding wire terminated with a one megohm
resistor and No. 10 ring terminal and a grounding bolt
complete with single wrist strap banana jack connection
terminal.

2. Item No. 14246, our Flush Mount Laminate Ground
Insert with Bench Ground is also available without a dual
wrist strap ground sold as Item No. 14244. Both 14244
and 14246 can be easily installed with our Drill Kit Item
No. 14242.
