A basic procedure based upon the SAE method is listed below and may be used for convenience. 5.2.1 Apparatus 5.2.1.
19、1 Millipore Filter Assembly 5.2.1.2 Vacuum Filtering Flask 5.2.1.3 5 micron and 0.5 micron Millipore Filter paper. 5.2.1.4 Suitable Solvent, such as n-pentane, hexane, petroleum ether, or a clean wash solution at same concentration as washer using deionized water. 5.2.1.5 Pressure tank with filter (
20、similar to Millipore Model # XX6700L05) 5.2.2 Procedure: Method 1 5.2.2.1 Wash all apparatus carefully to avoid introducing extraneous contaminants. 5.2.2.2 Clean the exterior of test components as necessary to avoid introducing extraneous contaminants. 5.2.2.3 Pre-filter the solvent to be used thro
21、ugh a 0.5 micron Millipore filter paper. Store the filtered solvent in a clean container until it is used. 5.2.2.4 Dry a 5 micron Millipore filter (with grid) in an oven at 100C (212F) for 15 minutes. Cool to room temperature and weigh to the nearest 0.1 mg. 5.2.2.5 Thoroughly flush the designated t
22、est surfaces with the filtered solvent, carefully collecting the solvent and debris into a clean beaker or container. 5.2.2.6 Pass this collected mixture through the 5 micron filter from Step 4, using the Millipore filter assembly, the vacuum filtering flask, and a vacuum source. The used solvent ma
23、y be discarded or refiltered through a 0.5 micron Millipore filter for reuse. 5.2.2.7 Remove the filter paper from the filter assembly. Dry in an oven at 100C (212F) for 15 minutes, cool in a dessicator, and reweigh to the nearest 0.1 mg to determine if the contaminant weight requirement is met. 5.2
24、.2.8 Using optical magnification equipment, examine the recovered debris to determine if the particle size limitation has been met. 5.2.3 Procedure: Method 2 (ISO 16232-3) 5.2.3.1 Equip the test liquid dispenser with one or more spray nozzle(s), suitable for the surfaces to be pressure rinsed. 5.2.3
25、.2 Adjust the pressure of the test liquid to obtain a jet of sufficient power to remove and transport the particles from the controlled surfaces without degrading or dissolving the surface material of the component. 5.2.3.3 Rinse the controlled surfaces carefully with test liquid sprayed on through
26、the nozzle, ensuring that the whole controlled surface has been swept by the jet in order to extract the particles from the component(s). Collect the extraction liquid in either a single or several sampling containers. 5.2.3.4 Collect all recovered extraction liquids and particles. Carefully rinse t
27、he collection equipment and collect all of the accumulated particles in a clean sampling container. 5.2.3.5 Analyze the extraction liquid in accordance with ISO 16232-6 (gravimetric analysis) or (particle sizing and counting) ISO 16232-7 and label the result obtained as S1. 5.2.3.6 Repeat 5.2.3.3 to
28、 5.2.3.5 twice more on the same component, using, when necessary, a different container for each extraction liquid volume and label the result obtained as S2 and S3. NOTE: The extractions should be made directly one after the other. NUMBER: MPAPS F-2 TITLE: Fluid System Cleanliness Requirements REVI

Suppliers are required to assume all patent liability. 2016 by Navistar, Inc. JUNE 2016 Page 4 of 7 5.2.3.7 Validate the contamination extraction pro
30、cedure to ensure its efficiency as follows: a) For each of the three samples analyzed in 5.2.3.5 and 5.2.3.6, establish the total mass of contaminants and/or the total number of particles. For the particle count, this is applicable to the total number of particles larger than the smallest particle s
31、ize specified in the inspection document. This particle size shall be chosen to enable counting significant numbers of particles; b) Divide the result of the last sample (S3) by the sum of all the values obtained in 5.2.3.7 a); c) If the value obtained is less than or equal to 10%, the end-point is
32、reached and the extraction is completed. NOTE 1: This procedure enables the extraction curve to be drawn and the end-point (u 0.10) to be demonstrated (see Figure 1). NOTE 2: The cleanliness level of the component is the sum of the extractions. NOTE 3: In some cases (for example: a very low contamin
33、ation level, difficulties in extracting particles, inappropriate blank level, etc.) the extraction curve may not be of the form seen in Figure 1. If this is the case, it is ensured that all extraction parameters have been properly investigated. d) If the value obtained is 0.10, a further extraction
34、is necessary. Repeat stages 5.2.3.3 to 5.2.3.7 until the last sample (Sn) produces a result u 0.10 of the total of the whole samples ( 10100 =1 ) 5.2.3.8 If six extractions have been performed without reaching a value u 0.10, then the extraction parameters are not suitable and shall be modified. The
35、n repeat operations 5.2.3.3 to 5.2.3.7 with new parameters on a new component. 5.2.3.9 If this criterion is not fulfilled, set up a new extraction protocol and validates it according to 5.2.3 or apply another extraction method as defined in ISO 16232-2, ISO 16232-4 and ISO 16232-5.
