ASTM D4949-94

ASTM D4949-94 - 1.1.1994

1. Scope

1.1 This test method describes the procedure for determination of both surface and volume (bulk) d-c resistivity of writing paper. This test method is specific for the Keithley 6105 resistivity adapter.

1.2 This test method has been developed as a special case for use on writing papers processed in high-speed nonimpact printers where resistivity control is critical. It is not in conflict with Test Method D257.

1.3 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.
