ISO 284:2012 specifies the maximum electrical resistance of a conveyor belt and the corresponding test method.
The test is intended to ensure that the belt is sufficiently conductive to avoid the accumulation of electrical static charge which can be developed during service use.
ISO 284:2012 is not suitable or applicable to light conveyor belts as described in ISO 21183-1, the static electrical properties of which are measured by ISO 21178.
