Point To Ground Method Esd Flooring Checking

If an anti static mat is isolated from electrical ground by insulators carpets painted floors or tables you need to connect it to an electrical outlet by using a grounding cable.

Point to ground method esd flooring checking.

Resistance to ground testing rtg to qualify a flooring product you will need five 12 x 24 samples with two groundable points per sample. Scope this test method covers the determination of electrical conductance or resistance of resilient flooring either in tile or sheet form for applications such as hospitals computer rooms clean rooms access flooring munition plants or any other environment concerning personnel generated static electricity. Many of the test methods ansi esd stm7 1 and astm f150 are developed to report the characterization of esd floor materials and more importantly their performance in combination with a person wearing.

Only use electrical receptacles outlets that have been previously tested using an approved circuit tester complying with csa and or ul standards. The resistance tests verified that the floor measured below 1 0 x 10 7 easily complying with the resistive properties of a static control floor based on ansi esd s20 20. All five samples must be conditioned for the full 72 hours at low humidity. There are several esd floor test methods associated with and recommended by voluntary associations with a keen focus on the phenomenon and control of static electricity in work environments.

Each sample will be tested 6 times from both ground points per the diagram below. The purpose of painting your floor with esd paint is to remove static. The desco digital surface resistance meter kit measures resistance point to point rtt or surface to ground rtg of worksurfaces flooring systems garments and other materials in accordance with esd association documents. The three most widely used procedures are described below.

Tests included point to point rtt and point to ground rtg measurements. You should connect all grounded people and equipment to an electrical outlet electrical outlets follow the piping to the earth underneath building. It covers the range of ways that wrist straps personnel and mats can be electrically bonded grounded. The snap is where you will connect the grounding cable.

Normally one grounding point is required for every 1000 ft2 111 m2 of flooring. Grounding esd static control flooring several acceptable methods are used to ground static control flooring depending on local codes the job conditions and the personal preference of the contractor. The samples should be numbered from 1 to 5. Grounding is a simple easy process.

Affixing the copper grounding strap to the floor tile or static control floor coating. The standard governing workstations is ansi esd 6 1. The paint will absorb the static charge but it needs somewhere to escape via a grounding point. Grounding cables end in eyelets so that you can tie them into the outlet.

Esd tr53 ansi esd s4 1 ansi esd s7 1 ansi esd stm97 1 and other documents. To ground anti static mats we insert a conductive snap on the corner of the anti static mat.
