ISO 2211:1973 Liquid chemical products Measurement of color in Hazen units (platinum-cobalt scale)

This International Standard describes how to measure a liquid chemical product's color in the Hazen units’ technique. It can only be used on clear, faintly colored liquids whose color properties are similar to the platinum-cobalt reference scale. In general, these color features can be described as "brownish-yellow." This procedure can be used anywhere an ISO recommendation or standard about a particular product specifies it.

    Introduction to ISO 2211:1973

    The principle of ISO 2211:1973 is based on the expression of the result in terms of Hazen (platinum-cobalt) color units and the visual comparison of a sample’s color with color standards. An instrument like a comparator, calorimeter, or spectrophotometer may be used for routine control purposes, but only when it has been proven that the results acquired this way are identical to those obtained through visual comparison. MaTestLab is one of the best testing service providers, with the best network of testing laboratories in the USA to carry out ISO 2211:1973 tests for our clients.

    ISO 2211:1973 Test Method

    Visual checkingThe sample is checked so that it has a color that matches those of the standard Hazen matching solutions
    PouringThe Hazen matching solution and the sample with the same colors are filled in different colorimetric tubes up to the graduation marks.
    Color ComparisonLooking down the tubes from top to bottom against a white background brightly lit by either natural light or an electric “daylight” lamp, and being careful not to allow any side lighting, the color of the sample is compared to that of the standard.

    ISO 2211:1973 Test Specimens

    Specimen DetailsLiquid-colored chemical product samples are the test specimens for ISO 2211:1973
    Specimen SizeWhen measuring low colorations (less than 50 Hazen units), the graduation mark height above the base must be higher than when measuring deeper colors. It also needs to be high enough to allow one to see the standard Hazen matching solutions clearly through the deeper liquid.

    ISO 2211:1973 Test Results

    ISO 2211:1973, which can be used to detect contaminants and quality deviations in solvents and oils, uses Hazen units (a platinum-cobalt scale) to measure the color of liquid chemical products. The ISO 2211:1973 process entails meticulous preparation of the sample, comparison with standard Hazen solutions in a uniform lighting environment, and correction for low colorations.
