Implication

Methodological review reveals significant measurement-induced conductivity discrepancies in low-density polyethylene, indicating that testing protocols heavily bias observed electrical properties.

Key Points

Identify the primary causes of widespread discrepancies in reported electrical conductivity and field dependence values for low-density polyethylene.
Assessed experimental variables influencing current measurement, including the duration of voltage application to electrodes.
Analyzed the effects of sample conditioning through thermal treatment and pre-measurement voltage stressing on conduction behavior.
Discrepancies in conductivity across studies stem primarily from differing measurement techniques rather than variable impurity levels among polyethylene sources.
Elapsed time following voltage application and sample preconditioning significantly modify current flow, challenging the assumption that achieving steady-state current is mandatory for assessing true conductivity.
