ASTM D5452-23 pdf free download -Standard Test Method For Particulate Contamination In Aviation Fuels By Laboratory Filtration.
1.1 This test method covers the gravimetric determination by filtration of particulate contaminant in a sample of aviation
turbine fuel delivered to a laboratory.
1.1.1 The sample is filtered through a test membrane and a control membrane using vacuum. The mass change difference identifies the contaminant level per unit volume.
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
4. Summary of Test Method
4.1 A known volume of fuel is filtered through a preweighed test membrane filter and the increase in membrane filter mass is weight determined after washing and drying. The change in weight of a control membrane located immediately below the test membrane filter is also determined. The objective of using a control membrane is to assess whether the fuel itself influences the weight of a membrane. The particulate contaminant is determined from the increase in mass of the test membrane relative to the control membrane filter.
4.2 In order to ensure safety in handling, the test method requires that volatile fuels be transferred from the sample container to the funnel without pouring using a support stand shown in Fig. 1.
