1   Scope

  This part of [IEC 61340](/search?q=IEC%C2%A061340)
   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](/search?q=IEC%C2%A061340%E2%80%914%E2%80%916) which can be used for garments so equipped with cuffs that are intended to perform
  the same function as a wrist strap band.
