San Pedro St., Gardena, CA 90248 is placed in a 1000 mL beaker with stir bar. The soybean oil in the beaker is placed on a hot plate and heated to 204°C while stirring slowly. Air is added through a glass pipette tip set to bubble continuously through the oil. The oil is cooked continuously until viscosity, at 25°C ⁇ 2.2°C, is between 150 and 200 cP. The color changes to a dark orange. Viscosity is measured using a Cannon-Ubbelohde Viscometer tube # 350 available from Cannon Instrument Company, State College, PA 16803, or equivalent viscometer.

Separately the fluid density is determined by measuring the weight of a fixed volume of oil using a 25 mL volumetric flask and a 4 place analytical balance. Viscosity in cP can be calculated by multiplying the Kinematic viscosity by density of oil in g/mL.

  • the second application of the model soil suspension is applied to each mirror surface in a circular motion, moving from the outside (approximately 8-10 inches from the side edges) inward toward the center.
  • the mirrors are ready to be cleaned with an article of manufacture ("specimen") to be tested. If the time between soil application and cleaning of the mirrors with a test sample extends past 30 minutes, the mirrors need to be returned to their pristine condition using the procedure define previously after which the soil application procedure can be repeated.

  • the mirror surface is cleaned by grasping the sample pad in the hand, clamping the substrate between the thumb and index finger and wiping with firm pressure in a cross direction, while holding the sheet (side 1) as flat as possible upon the surface of the mirror and avoiding contacting the mirror with any part of the hand using 8 side-to-side passes, such that the full surface of the mirror is contacted.
  • the sample pad is then turned over and the relatively dry back-side (side 2) is used to wipe the mirror surface in an up and down motion, with firm pressure applied using 14 passes, ensuring that the entire surface of the mirror is contacted, again holding the sample pad as flat against the mirror surface as possible.
  • the sample pad is then unfolded once and then folded back on itself revealing a relatively fresh sample pad surfaces to clean the second mirror after application of Windex as discussed above; side 3 (opposite side 1) is used for the side-to-side wiping and then turned over to side 4 (opposite side 2) for the up and down wiping.
  • the pad is then unfolded twice to reveal a fresh surface of the specimen.
  • the specimen is then folded in half such that the fresh sample surface is visible with the two used areas of the first sample pad configuration (sides 1 and 3) facing each other and then folded again to clean the third mirror surface after application of Windex as discussed above.
  • Side 5 opposite side 1 and 3 is used first and then turned over to side 6 for the second up and down wiping.
  • the sample pad is unfolded once and then folded back on itself revealing sides 7 and 8 to clean the fourth mirror surface after application of Windex as discussed above.

  • the wettest part of the folded sample pad is used for the side-to-side wiping and the dryer side for the final up and down wiping.
  • All 4 mirror surfaces should be cleaned sequentially such that minimal drying of the specimen pad occurs. After cleaning all four mirror surfaces, the mirror surface is permitted to dry and each mirror surface's optical density is measured utilizing an X-Rite 518 Spectrodensitometer. A full calibration as described in the operator' s manual is performed. The instrument is set-up per instructions in the manual in Density minus Reference Measurement Mode. The four 28"x 28" mirror surfaces were cleaned as described above representing a pristine condition. A single reading of a mirror in pristine condition is completed and stored as Ref 1 and is used as a reference for all subsequent measurements.
  • a series of 9, 12, or 15 measurements are made on each of the 4 mirrors (3, 4, or 5, respectively, across the top, 3, 4, or 5, respectively, across the middle and 3, 4, or 5, respectively, across the bottom always maintaining a minimum of 3 inches from any edge of the mirror) as shown in Fig. 2 for example.
  • the mirror cleaning test stand is oriented in the lab such that there is no direct overhead lighting and rotated such that the mirror being measured is facing towards an interior wall thus minimizing any influence caused by external lighting differences. Measurements were performed on each of the pristine mirrors. These 9, 12, or 15 individual values are averaged for each mirror. The average values were found to be consistent between mirrors, however, as expected the average shows a small difference from the single point reference. This difference is used to correct all subsequent average values measured.
  • average values were determined for mirrors after application of the model soils. After, following the cleaning procedure with the sample specimen, 9, 12, or 15 density readings are performed and an average Densitometer Value is reported for each of the individual mirrors.
  • the Average Mirror Cleaning Densitometer Value is the average of the average Densitometer Values across all 4 mirrors. The orientation of the mirrors and room lighting is such that streaks are not readily visible thus insuring a random location of each measurement taken within the limitations of the 3x3, 3x4, or 3x5 grid described above.

This method is performed by first weighing a sample of the fibrous structure to be tested (referred to herein as the "dry weight of the sample”), then thoroughly wetting the sample, draining the wetted sample in a vertical position and then reweighing (referred to herein as "wet weight of the sample”).

While the sample is draining, the rack cover is carefully removed and all excess water is wiped from the support rack. The wet sample and the support rack are weighed on the previously tared balance. The weight is recorded to the nearest O.Olg. This is the wet weight of the sample.
