Reference Standards for Anti-Static and Conductive Parameters (Standard Parameters for the Anti-Static and Conductive Properties of Conveyor Belts)

Non-conductive (NA): insulating, suitable for inspection conveying with high precision requirements.

Ordinary conductive: the fabric in the middle layer or bottom layer of the belt body is conductive, resistivity < 3×10^8 Ω, and the belt body is conductive in the longitudinal direction.

Highly conductive 1 (HC): surface resistivity < 5×10^7 Ω

Highly conductive 2 (HC): surface resistivity < 10^7 Ω, belt body resistivity < 10^9 Ω

ESD: upper and lower surface resistivity 10^3–10^6 Ω

ATEX: surface resistivity < 5×10^7 Ω, belt body resistivity < 10^9 Ω, explosion protection test (2G/2D)
