Note 1:

Accelerated Storage Stability: Place a 50ml portion of thoroughly mixed Preventative Solution, as received, in each of three (3) stoppered 100 ml graduated cylinders. Put all three samples in a low temperature environment @ 20 ± 2°F (2 ± 1°C) for 30 min. Remove cylinders; allow them to return to room temperature. Then place all three samples in a hot environment @ 105 ± 2°F (44 ± 1°C) for 30 min; allow to air cool to room temperature. Repeat this freeze-thaw cycle two more times. Record all visible changes including layering, separation and precipitation.

Note 1:

Combine 50g of struvite with 200g of mineral Removal Solution in covered beaker. Mix for 20 minutes, remove cover and whaft/sniff for any odors. No obtrusive odors.

Note 2:

Place a 50ml portion of thoroughly mixed SOAK Solution, as received, in each of three (3) stoppered 100 ml graduated cylinders. Put all three samples in a low temperature environment @ 20 ± 2°F (2 ± 1°C) for 30 min.

Remove cylinders; allow them to return to room temperature.

Then place all three samples in a hot environment @ 105 ± 2°F (44 ± 1°C) for 30 min; allow to air cool to room temperature. Repeat this freeze-thaw cycle two more times. Record all visible changes including layering, separation and precipitation.

Note 3:

Heat Stability: Fifty (50) ml of the concentrated Removal Solution shall be placed in a 50 ml graduate mixing cylinder, the cylinder shall be stoppered. The cylinder shall be placed in a 60°C

+/- 2 C (140°F +/-3°F) water bath and maintained at that temperature for six (6) hours. The water bath shall be sufficient depth to cover at least 30 ml of the Removal Solution. At the end of the test period, no separation or layering of the Removal Solution shall be evident.

Cold Stability: Fifty (50) ml of the concentrated Removal Solution shall be placed in a 50 ml graduated cylinder, the cylinder shall be stoppered and cooled to a -18°C +/-5°C (0°F – 9°F). This temperature shall be maintained for one (1) hour. The Removal Solution shall then be allowed to return to room temperature (75°F – 80°F). At the end of this test period, no separation, precipitation or layering of the

Removal Solution will be evident.

Note 4:

Test Removal Solution as received. Place 45 ml of DI Water in graduated cylinder. Add 5ml concentrated

Removal Solution and conduct 30 pivotal movements in 30 seconds. Read foam level immediately, at 3 minutes, and 5-minute intervals.

Note 5:

Insoluble Matter: The concentrated Removal Solution shall be thoroughly agitated and a 200 mg test sample withdrawn. The insoluble matter shall be collected with the aid of a vacuum filtering apparatus consisting of a water tap filter pump, a 2,000 ml Erlenmeyer flask, a size 4 (126-millimeter (mm)) Whatman No. 5 filter paper, or its equivalent. The filter paper shall be dried at 60°C (140°F) for 30 minutes in a gravity convection oven, cooled for three (3) minutes in a desiccator and weighed to the nearest 0.1 mg. The filter paper shall be

Any alterations to this document made by the Offeror may be grounds for rejection of the proposal, cancellation of any subsequent award, or any legal remedies laced in the Buchner funnel so that its circumference coincides with the circumference of the funnel. The vacuum shall be weighed to the nearest .1 mg then filtered. The sides of the beaker, which contained the test sample shall be rinsed with 25 cc of distilled water from a wash bottle and the rinse transferred to the funnel, ensuring that any remaining insoluble matter is completely transferred with the rinse. When all the initial liquid and the rinse have been transferred through the filter, the sides of the funnel shall be washed with 25 cc of distilled water from a wash bottle and the rinse allowed to filter. The vacuum on the flask shall be relieved and the filter paper removed from the funnel. The filter paper shall be dried for one (1) hour at 60°C (140°F) in a gravity convection oven, cooled for three (3) minutes in a desiccator, and weighed to the nearest 0.1 mg.

The percent insoluble shall be calculated as follows:

Final filter paper weight – initial filter paper weight x 100 = % insoluble

Weight of Sample

Care should be exercised throughout the final drying and weighing cycles to maintain the flat surface of the filter paper in a horizontal position in order that none of the insoluble matter will be lost. Insoluble matter determinations shall be made on a minimum of two samples. The average of these samples must be less than

0.1%.

Note 6:

Immerse (3) neoprene O ring, HNBR O ring and Viton O ring specimens in a 200ml concentrated Removal
