ASTM D3652/D3652M-93(1999)

Standard Test Method for Thickness of Pressure-Sensitive Tapes

SCOPE
1.1 This test method covers the determination of the thickness of pressure-sensitive tapes at standard conditions.
1.2 The values stated in either SI or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system must be used independently, without combining values in any way.
1.3 This test method is intended to replace AFERA 4006 and PSTC 33.
1.4 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.
