APHA color, also referred to as the Hazen scale, and more appropriately as the Platinum Cobalt(Pt/Co) scale, [1] is a color standard named for the American Public Health Association and defined by ASTM D1209. [2] It was originally intended to describe the color of waste water, but its usage has expanded to include other industrial applications ...

Pure water tends to look cyan in color and a sample can be compared to pure water with a predetermined color standard or comparing the results of a spectrophotometer. [ 13 ] Testing for color can be a quick and easy test which often reflects the amount of organic material in the water, although certain inorganic components like iron or ...
The Platinum-Cobalt Scale (Pt/Co scale or Apha-Hazen Scale) is a color scale that was introduced in 1892 by chemist Allen Hazen (1869–1930). The index was developed as a way to evaluate pollution levels in waste water. It has since expanded to a common method of comparison of the intensity of yellow-tinted samples.

Once again, the Joint Electron Device Engineering Council (JEDEC), now the standards body for semiconductor packaging, went to the descendants of R.

In this case the sample is contained in a test tube; the tube is inserted into the instrument, and the color properties of the liquid read out on a screen. This method can provide objective measurements, but is far more expensive than a set of color standards.
