- One key aspect in developing a new refrigerant is to test its compatibility with typical metals that are used in refrigeration and air conditioning equipment. Tests are typically performed by adding a given amount of the test substance into a high pressure glass vessel that contains copper, steel and aluminum coupons. The glass vessel is then sealed and thermostated at a given temperature. When the test is completed the initial analysis is determined by simply looking at the color of the fluid in the tube. It is therefore important that the initial color of the refrigerant is documented so that it can be compared to the final samples

Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
