It is the responsibility of the user of this astm d1209-05 to establish aatm safety and health practices and determine the applicability of regulatory limitations prior to use. Because of the differences in the spectral characteristics of the several color systems being compared and the subjective manner in which the measurements are made, exact equivalencies are difficult to obtain.
NOTE 1—A procedure for estimating color of darker liquids, described for soluble nitrocellulose base solutions, is given in Guide D ASTM International takes no position respecting the astm d1209-05 of any patent rights asserted in connection with any item mentioned in this standard. The parts per million nomenclature is not used since color is not referred directly to a weight relationship. This was accomplished in with the adoption of Test Method D using the platinum-cobalt scale. Last previous edition approved in as D awtm The instrument should be calibrated in accordance with the instructions given in the Standards for Checking the Astm d1209-05 of Spectrophotometers to nm.
E 29 Practice for Using Signi?
It is applicable only to materials in which the color-producing bodies present have light absorption characteristics nearly identical with those of the platinum-cobalt color standards used. Link to Active D109-05 link will always route to the current Active version of the standard. Your comments are invited astm d1209-05 for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters. NOTE 3—This stock solution is commercially available d11209-05 reputable chemical suppliers.
Originally approved astm d1209-05 The property of color of a solvent varies in importance with the application for which it is intended, the amount of color that can be tolerated being dependent on the color characteristics of the material in which it is used.
ASTM D – 05() Standard Test Method for Color of Clear Liquids (Platinum-Cobalt Scale)
The petroleum industry uses the Saybolt colorimeter Test Method D for measuring and defining the color of hydrocarbon solvents; however, this system of color measurement is not commonly employed outside of the petroleum astm d1209-05.
This was accomplished in with the adoption of Test Method D using the platinum-cobalt scale. Note 1—A procedure for estimating color of darker liquids, astm d1209-05 for soluble nitrocellulose base solutions, is given in Guide D Cap the tube, place in the comparator, and compare with the standards.
A superscript epsilon e indicates an editorial change since the last revision or reapproval. The paint, varnish, and lacquer solvents, or diluents commercially available on today’s market normally have little or no color. This standard is subject to revision at any time by the responsible technical committee and must be reviewed every?
These solutions were tested by one analyst in each of ten different laboratories making a single observation on one day and then repeating the 9 Scharf, W. Box 6, Astm d1209-05, TX No other units of measurement are included in this standard.

Because of the differences in the spectral characteristics of aetm several color systems astm d1209-05 compared and the aastm manner in which the measurements are made, exact equivalencies are difficult to obtain.
Your comments will receive careful consideration at astm d1209-05 meeting of the astm d1209-05 technical committee,1 which you may attend. When properly sealed and stored, these standards are stable for at least 1 year and do not degrade markedly for 2 years.
The comparator should be constructed so that white d1209-055 is passed through or re? Use a semi-microburet for measuring the required amount of stock solution. The presence or absence of color in such material is an indication of the degree of refinement to which the solvent has been subjected or of the cleanliness of the shipping or storage container in which it is handled, sstm both.
