ASTM D5452 Standard Test Method for Particulate Contamination in Aviation Fuels by Laboratory Filtration
1. Scope
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.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. For specific hazard statements, see 4.2, 7.3, 7.5, 11.2, and X1.7.2. Before using this standard, refer to supplier's safety labels, material safety data sheets, and technical literature.

3. Terminology
3.1 Definitions:
3.1.1 bond, v - to connect two parts of a system electrically by means of a bonding wire to eliminate voltage differences.
3.1.2 ground, vt - to connect electrically with ground (earth).
3.1.3 membrane filter, n - a porous article of closely controlled pore size through which a liquid is passed to separate matter in suspension.
3.1.3.1 Discussion - Research Report RR:D02-1012 contains information on membrane filters that meet the requirements therein.
3.1.4 particulate, adj - of or relating to minute separate particles.
3.1.4.1 Discussion - Solids generally composed of oxides, silicates, and fuel insoluble salts.
3.1.5 volatile fuels - relatively wide boiling range volatile distillate.
3.1.5.1 Discussion - These are identified as Jet B in Specification D6615 or the military grade known as JP-4. Any fuel or mixture having a flash point less than 38°C is considered to be volatile.
