GB/T 14447-1993

This standard specifies a test method for measuring the electrostatic decay half-life of plastic films, quantifying how quickly static charge dissipates from the material surface. It is applied in the rubber and plastics industry for quality control and material selection, particularly for packaging films, electronic component wraps, and cleanroom materials where static discharge could damage sensitive products or attract contaminants. The half-life method provides a standardized metric to evaluate antistatic treatment effectiveness and ensure compliance with industrial safety requirements.
