Scope

1.1 This test method covers the measurement of the surfaceirregularitiesof flat transparent plasfic sheetsthat are ordinarily used to cover openings through which visual and instrumental observationsare made. 1.2 This test method measures the distortion and the deviation of line of sight through flat sheets of transparent plastics. The test method makes use of the prismatic or optical wedge deflection of a beam of light as it passes through a distortion spot or wave in the body of or on the surface of the material being inspected, 1.3 The values stated in SIunits are to be regarde.d as the standard. 1.4 This standard does not purport to address the safity problemsassociatedwith its use, It isthe responsibilityo f the user o f this standard to establish appropriate safity and healthpractices and determinethe applicabilityo f regulatory limitationsprior to use.
