steel back plate
C. 4mm snap stud
machined from 300 series stainless steel. Fits to 4mm spring loaded medical
type socket. Coil cord disengages from snap with 1-5 lbs. of
perpendicular force, fulfilling ESD-S1 paragraph 4.1.6 breakaway force
requirement. Durable, providing long life well beyond that of
sheet metal snaps.
elastic band material of light blue fiber. 1.125" (32 mm) wide and
0.10" (2.54 mm) thick, 65 strands of textured polyester,
46 strands of Lycra spandex and 14 strands of silver
plated polypropylene yarn. Made with pure silver irreversibly
bound to fibers providing both antimicrobial and anti-odor performance.
Outer surface of light blue fibers act as an insulator
conductive silver plated polypropylene (see D) represents 14.5% of the material
by weight. The 14 strands of conductive polypropylene are
uniformly knit on the inner surface of the material and are
electrically isolated from the outer surface (blue side).

What the ESD Association says about testing wrist straps:
Per ESD Handbook TR20.20 section 126.96.36.199 Wrist Strap Checkers -
"Wrist strap checkers have historically been the primary tool for testing
the operation of the wrist strap system including, the wristband, grounding
cord, and most importantly, the electrical integrity of the contact between the
wristband and the wearer. Wrist strap checkers measure the resistance of
the entire system."
Circumference - 2.5" - 13"
Note: All bands have a 4mm snap stud. Complete wrist strap kits include
an alligator clip. Wrist strap kits include an alligator clip for
occasions when a grounded banana jack is not available. However, best
industry practice is that ESD Ground Connections should be firm fitting
connecting devices such as metallic crimps, snaps and bana plugs to be
connected to designated ground points. Use of alligator clips is not
recommended. (Ref: JEDEC Standard No. 625-A)
ANSI/ESD S20.20 Paragraph 188.8.131.52 Personnel Grounding
Requirement " ALl personnel shall be bonded or electrically connected to
ground of contrived ground when handling ESD sensitive tems. When
personnel are seated at ESD protective workstations, they shall be connected to
the common point via a wrist strap system."
