Facts about the ASTM D7066 Standard Test Method
The ASTM D7066 standard test method is used for dimer/trimer of chlorotrifluoroethylene (S-316) Recoverable Oil and Grease and Nonpolar Material by Infrared Determination.
The ASTM D7066 may be a useful method but it is based on ozone-depleting substances. As stated in the Montreal Protocol and also reported to the UN, such standards are no longer state of the art. Therefore our ERACHECK is measuring according to the environment friendly ASTM D7678 method. (Andreas Schwarzmann, R&D)
ASTM D7066 defines oil and grease in water and wastewater. The method measures by IR absorption at 2930 cm-1 or 3.4 microns. It covers the range of 5 to 100 mg/L and may be extended to a lower or higher level by extraction of a larger or smaller sample volume collected separately.
