Description

ASTM D589-97-Reapproved2002

Historical Standard: Standard Test Method for Opacity of Paper (15°Diffuse Illuminant A, 89% Reflectance Backing and Paper Backing)

ASTM D589

Scope

1.1 This test method covers the determination of the opacity of paper.

1.2 Two different types of “white” backing are specified, leading to two different opacity values, in accordance with Section 3.

1.3 This test method employs 15° diffuse geometry, Illuminant A/2 and 89 % reflectance backing or paper backing. For the measurement of opacity with d/0 geometry, Illuminant C/2 and paper backing (see TAPPI T 519).

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.
