But some garment manufacturers let users connect a wrist strap directly to a garment's sleeve hem. In this case, a standard ground cord provides a single ground path from the hip of the garment, thus freeing the user's arms from long ground-cord connections. This type of apparel does not offer as high a level of electrical continuity between various panels or garment parts. But it can provide a barrier between the static charges generated on a person's clothing and static-sensitive components. The carbon web built into these garments dissipates charges evenly across the entire garment surface and into the surrounding atmosphere through a process known as corona discharge.
Performance depends on temperature and relative humidity.
When you work with highly sensitive components, you should use a grounded garment. For those applications where grounding is critical, vendors also offer garments compatible with dual-loop ground monitors. This setup ensures that as soon as the path connecting ground to the garment or the body of a technician breaks, a monitor beeps and a supervisor can rectify the problem. These monitoring systems provide an effective way to limit losses due to ESD when people work with highly sensitive components. The document defines procedures available to measure the electrical resistance of a garment.
