It is highly recommended that instrumental readings be corrected for? The asttm method should be used to verify the zero reading in instruments that do not require such a calibration step.
Care must be taken to correct for this error 3, Test Method D See also Guide E and Practice E This standard is not included in any packages.
Care should be taken not to touch the area to be measured except for application of a suitable cleaning procedure. 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.
The considerations involved and the procedures used to obtain precise spectrometric data are contained in this practice. For example, the value of the re? Special considerations for the interactions between an 5 instrument geometry and the specimen surface are cited in the following sections and will also apply to the formulation of product colors.
The requirements for illuminating and viewing may be interchanged. However, for the measurement of? NOTE 4—Corrections for errors in the use of integrating spheres for the 8. If the document is revised or amended, you will be notified by email.

Tt and the measurement provides the total transmittance factor Tt. Last previous edition approved in as E — The preferred geometry will be the one that minimizes the surface effects, thereby optimizing the separation.

Special precautions, outlined here, must be observed to minimize the effects of aastm characteristics; the use of special equipment beyond the scope of this practice may be required to eliminate the effects entirely.
The spectrometer may be either a typical asrm spectrometer, designed speci? Commonly used light sources include incandescent lamps, either operated without? As the voice of the U.

In these cases, it may be more appropriate to use larger cone atsm, with appropriate tolerances. When the degree of directionality of the specimen is to be evaluated, uniplanar geometry should be used.
In such cases, it is recommended 5 to use the substitution method of measurement rather than the comparison method 3. We have no amendments or corrections for this astn.
