TECHNICAL DATA 2022.10.26

Antistatic propertyof Vinyl Sheets, Tiles & Carpet Tiles

Use below data as a performance index to prevent malfunctioning of electronic equipment from human's static.
As indoor air is controlled better now, ﬂooring materials ranked C or better are mostly suﬃcient as the ﬂooring at hospitals, welfare facilities for old people andresidence as well. In order to prevent malfunctioning of inspection devices, ‘rank’ and ‘guide for uses’ shall be referred to for ﬂoor selection.
The ﬂooring with less resistivity has better
property to discharge electricity.

General grade: where generation of staticelectricity is not a concern

Antistatic property of vinyl ﬂoor covering is evaluated by volume resistance value.
The less the resistance is, the quicker the static electricity is discharged. And themore humid a room is, the more quickly the electricity is discharged.

● Test Method

Antistatic property test (at 23°C ,25%RH)

1. Surface resistance test

1. Surface resistance test (Independent test by TOLI)With the use of the Super-Insulation Resistance Tester, check the direct current
through ﬂooring between two electrodes.The less resistance means the lesscharge of static electricity.
2. Volume resistance test (according to JIS A 1454)
With the use of the same tester as “1”, check the electric resistance between twoelectrodes. One is placed on ﬂooring, the other is connected to the metal plate. The
smaller the resistance is, the less static electricity is generated.

Test method to measure the static charge of a human walking.
This Japanese original test method is widely adopted in Japanese carpet
industry according to JIS,and the static charge below 3 kV is usually recognized assafe level. Note; Although vinyl ﬂoorings are installed with adhesive at job
sites, a test piece in this method is loose-laid on insulation material. Thus,
static charge to a human walking in actual case may show lower value than thistest result.

● Test Method

Assessment of static electricity charge−Walking test (in accordance to JIS L 1021-16)
This test is to measure static charge to human by stepping on ﬂoor specimen. The
less charge represents the better antistatic property (at 23°C,25% R.H./ Shoes ofsynthetic rubber sole.).
