Scope

1.1 This practice covers procedures for preparing pressed powder transfer standards of reflectance factor. These standards can be used in the near-ultraviolet, visible and near-infrared region of the spectrum. Procedures for calibrating the reflectance factor of materials on an absolute basis are contained in CIE Publication No. 44 (2). Pressed powder standards are used as transfer standards for such calibrations because they have a high reflectance factor which is nearly constant with wavelength and because the distribution of reflected flux resembles that from the perfect reflecting diffuser.

1.2 This standard does not purport to address all of the safety problems, 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.

1.3 The values stated in SI units are to be regarded as the standard. The values in parentheses are for information only.
