The test method defined in the ASTM F331-13 standard developed by the American Society for Testing and Materials (ASTM) involves the determination of the non-volatile substance in the solvent extract from aerospace components, ie the residue on evaporation, using a rotary flash evaporator. This standard provides a summary of the test method, apparatus for the test, reagents and materials for the test, and the test procedure in detail.

The procedure for extracting particles from components is described in the ASTM F303-08 Standard Practices for Sampling Particles in Aerospace Fluids and Components standard.
Before the extract is subjected to the test method defined in ASTM F331-13, it must be processed to remove insoluble particles according to the procedure defined in ASTM F311-08. Particle count analysis of the extracted particles is then performed according to ASTM F312-08.
Membrane filters with a maximum extractable content of 331 percent by weight should be used for samples to be processed with the ASTM F13-0,5 test method. Conventional membranes contain 5 to 10 percent extractables. Care should be taken to use membranes without grid marks to achieve very low background levels.
Non-volatile residue or non-volatile matter is the soluble, suspended or particulate material that remains after evaporation of the volatile solvent containing the material. Non-volatile residue analysis is used to determine the purity of a solvent as well as to measure the amount of micro-contamination (ie cleanliness) on the surface of an item or component.
During the analysis, the organic solvent is evaporated, then the residue is measured gravimetrically using a precision balance and carefully tared weighing cups. This type of analysis is essential in the fields of water quality and environmental testing, as well as in the chemical, pharmaceutical, medical device and electronics industries.
In short, this analysis is important to control production processes and ensure compliance with standards.
