Special precautions, outlined here, must be observed to minimize the effects of these characteristics; the use of special equipment beyond the scope of this practice may be required to eliminate the effects entirely.
Detailed descriptions of these geometries can be found in the appropriate sections of Practice E Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility.

Care must also be taken to avoid discoloring of either area due to prolonged radiation or dirt, or partial translucency due to asttm thickness of the coating.
ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard. It also provides for instrument calibration by means of material standards, and for selection of suitable specimens for obtaining precision in the measurements. This practice is e11664 as to the materials to be characterized for color.
Precision and Bias This standard is also available to be included in Standards Subscriptions.
No other units of measurement are included in this standard. The detector must be stable with time and have adequate responsivity over the wavelength range used.

Care should be taken not to touch the area to be measured except for application of a suitable cleaning procedure. If the spectral interval and bandpass are greater than 1 nm then it is recommended that the spectral data be interpolated and then deconvolved 21 down to the 1 nm interval before computing tristimulus values as recommended in Practice E 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 s1164 colors.

When information on directionality is not required, the several measurements may be averaged. The presence of surface contaminants will critically affect the reliability of this standard. Blocking should be carried out by replacing the specimen with an opaque object of the same size and shape as the specimen, placed in the same position.
Whenever the cavity is employed it should always be presented to the instrument in the indicated orientation. See also Guide E and Practice E
