Your Alert Profile lists the documents that will be monitored. 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.
Commonly used light sources include incandescent lamps, either operated without? When the degree of directionality of the specimen asttm to be evaluated, uniplanar geometry should be used.
However, the use of a wider interval can lead to signi? When information on directionality is not required, the several measurements may be averaged. The detector must be stable with time and have wstm responsivity over the wavelength range used. If the document is revised or amended, you will be notified by email.
This practice is general as to the materials to be characterized for color. A still better method for characterizing? The instrument user must assume the responsibility for obtaining the necessary material standards. The condition of the specimens before and after measurement should be noted and reported. Standards Subsctiption may be the perfect solution.
Use of a wider interval, such as 10 nm or 20 nm, will result in a signi? No other units of measurement are included in this ast.

Each user must decide whether the loss of accuracy in his measurements is negligibly small for the purpose for which data are obtained. Examples of r1164 veri? In these cases, xstm may be more appropriate to use larger cone angles, with appropriate tolerances. Current edition approved June 1, If the black-cavity traps light by utilizing asymmetric or off-axis black optics then a preferred orientation of the cavity relative to the optical axis should be identi?

In other cases, use may be made of another white material, with assigned re? The detector may be a photoelectric device phototube or photomultipliera silicon photodiode or diode array, or another suitable photodetector.
