Jewel MagSnap Wrist Straps meet or exceed the requirements of ANSI/ESD S20.20 and
ANSI/ESD S1.1 including section 5.4 Breakaway Force “With the ground cord connected
to the cuff in a normal manner, a force of
≥ .45 kg (1 lb) but ≤ 2.3 kg (5 lb) applied to the
ground cord, in the normal disconnect direction, shall be required to separate the ground
cord from the cuff.”
Per ANSI/ESD S20.20 Paragraph 6.2.2.1. Personnel Grounding Requirements “All
personnel shall be bonded or electrically connected to ground or contrived ground when
handling ESD sensitive items. When personnel are seated at ESD protective workstations,
they shall be connected to the common point ground via a wrist strap system.”
“At first glance, the ground cord appears to be a relatively simple assembly. However,
the design requirements are considerable, given the wide range of user applications and
the durability requirements of constant tugging, flexing, and dragging over the edge of
workstation tops and equipment chassis.”
(ESD Handbook TR20.20 paragraph 5.3.2.2.2 Wrist Strap Ground Cord)
NOTE: Complete wrist strap kits include an alligator clip. Wrist strap kits include an
alligatorclipforoccasionswhenagroundedbananajackisnotavailable.However,“Wrist
strap ground cords must be connected to a groundable point or an equipotential bonding
point. Do not connect to a snap on a dissipative mat unless it is the groundable point
for the mat. Do not clip a wirst strap to the edge of a dissipative mat.” (ESD Handbook
TR20.20 section 5.3.2.7)
ESD Handbook TR 20.20 paragraph 5.3.2.4.4 Test Frequency “Because wrist straps have
a finite life, it is important to develop a test frequency that will guarantee integrity of the
system. Typical test programs recommend that wrist straps that are used daily should
be tested daily. However, if the products that are being produced are of such value that
knowledge of a continuous, reliable ground is needed, and then continuous monitoring
should be considered or even required”
Continuous Monitors pay for themselves improving quality, productivity, eliminating wrist
strap daily testing and test result logging. Per ESD-S1.1 paragraph 6.1.3 Frequency of
Functional Testing “Daily (Wrist Strap) testing may be omitted if constant monitoring is
used.”
