1 Scope
This part of IEC 61340
provides test methods for measuring the electrical resistance of garments used for
static control applications. These test methods can be used for evaluating outer garments
that are homogenously conductive or homogeneously dissipative, or that utilize surface
conductive or surface dissipative components or elements.
NOTE It is possible that the test methods defined in this document will not be able to
measure materials with buried conductive layers.
The resistance point-to-point test method tests the electrical resistance between
the two sleeves, any two panels or any two electrically interconnected components
of the static control garment, including the electrical resistance across the seams and cuffs of the garment as
applicable.
An alternate sleeve-to-sleeve test method is described, using clamps to hang a garment.
Static control garments that electrically bond to the wearer and provide a path to ground from the wearer
are evaluated using the resistance point-to-point test method, the resistance point-to-groundable
point test method, as well as a system test to determine the resistance from the person
through the garment to the groundable point of the garment system.
A band resistance measurement test is provided in IEC 61340‑4‑6 which can be used for garments so equipped with cuffs that are intended to perform
the same function as a wrist strap band.
The system test with a person wearing a groundable static control garment system includes the ground cord that connects to the groundable point of the garment.
