1.1 This practice describes methods for measuring the sheet electrical resistance of sputtered thin conductive films deposited on large insulating substrates (glass or plastic), used in making flat panel information displays.
1.2 This practice is intended to be used with Test Methods F 673
1.3 Sheet resistivity in the range 0.020 to 3000 Ω per square (sheet conductance in the range 3 by 10–4 to 50 mhos per square) may be measured by this practice. The sheet resistance is assumed to be uniform in the area being probed.
Note 1—Typical manual test units, as described in this practice, measure and report in the units “mhos per square”; this is the inverse of “ohms per square.”
1.4 This practice is applicable to flat surfaces only.
1.5 This practice is non-destructive. It may be used on production panels to help assure production uniformity.
1.6 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.7 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
