ASTM C1510 Spectrophotometry for Color Assessment

Scope:

Color parameters obtained by ASTM C1510 are used in industries where the specificity and accuracy of the colors are a priority. By measuring the absorbance, the concentration of the colors can be assessed. ASTM C1510 has many applications precisely in the ceramics industry due to its effective detection of color coordinates and numerical display of data. It defines all the properties of the color under observation. The importance of spectrophotometry in the whitewares industry is enormous as it is susceptible to analyzing and evaluating ceramic color.

Test Procedure:

The sample used for ASTM C1510 testing is kept in the spectrophotometer, and the lid is closed. Then it is turned ON and set to typical values, i.e., 380 nm absorbance wavelength and 0% transmittance. A lamp acts as the source of light. When the light falls on the sample, the diffraction grating in the spectrophotometer is rotated. The detector measures the transmittance and the absorbance of the model and displays it on its screen.

Data:

The value of the molar absorption coefficient for ASTM C1510 is measured using the equation:

Є=A/l 

where, 

Є is the molar absorption coefficient (M^-1cm^-1), 

A is absorbance (A), and 

l is the sample length (cm).

Conclusion:

ASTM C1510 captures, specifies, and evaluates the accuracy of the colors in ceramic glassware without affecting their composition.
