Changes to ISO 8573-2 standard for oil analysis
Following a periodic review of the existing ISO 8573-2 standard (published 2007), which specifies test methods for the sampling and analysis of liquid oil and oil aerosols, a number of changes have been implemented. These changes will enable more environmentally-friendly solvents to be used as well as making the standard easier to adhere to.
The primary reason for the change was to offer a greener solvent, as the existing standard specifies an ozone-depleting substance, which is both difficult to procure and expensive.
The secondary change was to introduce gas chromatography with flame ionisation detection, while continuing to allow the existing infra-red spectrometry, again with flame ionisation detection.
The new standard is now up to date with current detection methods and is easier to use and understand with clearer notes and diagrams. The document also includes a description of an alternative oil aerosol detection method using glass tubes. It is worth noting that this is for indication purposes only and cannot be used to comply with the new standard.
The new standard can be purchased from the BSI website.
