Anton Paar details the use of its PMA 5 in detailing the flash point of oil for its last Application Report.
A flash point is the lowest temperature corrected to a barometric pressure of 101.3 kPa (760 mm Hg) at which the application of an ignition source causes the vapours of a specimen of the sample to ignite under specified test conditions.
The PMA 5 automatically determines the flash point of diesel fuels, biodiesel, lubricants and other petroleum products in a range of 40 °C to 400 °C (104 °F to 752 °F). It fully complies with the related standard methods EN ISO 2719 or ASTM D93 where the different test procedures are implemented in the PMA 5.
Flash point values may be used in shipping, storage, handling and safety regulations as a classification property to define 'flammable' and 'combustible' materials. A flash point may also indicate the presence of highly volatile materials in a relatively non-volatile material and a flash point test may be a preliminary step to other investigations of unknown materials. This can be useful to determine the presence of gas or other contaminants in compressor oil and to give a general idea about the contamination grade.
