¹ Measurement only with thickness gauge DM-THICKGA.H00
Remark: Standards for elastomers and rubbers generally require the median out of 3 measurements.
Standards for plastics generally require the average out of 3 measurements.
Standards for cellular plastics generally require the average out of 5 measurements.
