4.4. pH: The pH value of a 1.0 percent solution of the detergent in distilled water shall be not less than 9.2 nor more than 10.6 at 77 °F when tested as specified in Paragraph 6.
4.5. Chemical and Physical Properties: The floor sealer shall conform to the following minimum chemical and physical requirements when tested according to Paragraph 6.
4.6. Foam Height: A 0.2 percent solution of the detergent at a temperature of 120 °F shall produce the foam height (lather value) shown in the following Table 2 when tested as specified in Paragraph 6.
FOAM HEIGHT, CENTIMETERS
|In 50 ppm Soft Water||In 50 ppm Soft Water|
|At Once||After 5 Minutes|
|4.0 Maximum||4.0 Maximum|
4.7. Container Sizes: The detergent shall be furnished in well constructed containers. The container sizes shall be:
(1) Five (5) pound box; 10 boxes per case
(2) 50 pound box or bag
(3) 100 pound bag
4.8. Purchase Unit: The purchase unit shall be net weight in pounds.
5. SAMPLES: Unless otherwise specified in the Invitation for Bids, no prepurchase samples shall be required. Samples tested shall be taken from regular orders.
6. TESTING: Testing shall be done by or at the direction of, the Commission and/or the receiving State agency. Tests shall be performed on products from shipments to ordering agencies. In the event products tested fail to meet or exceed all conditions and requirements of this specification, the cost of the samples used and the cost of testing shall be borne by the supplier.
6.1. TESTS: The product furnished under this specification shall be tested by the following methods or approved equally applicable procedures:
6.1.1. Chemical Analysis: The chemical components of the detergent, unless otherwise specified, shall be determined by the following paragraphs in Federal Specification No. P-D-245a and the following methods in Federal Test Method Standard No. 536:
|Chemical Compound||Federal Specification No. P-D-245a Paragraphs||Federal Test Method Standard No. 536 Methods|
|Nonionic Synthetic Organic Surfactant||4.4.2||6501|
|Polyphosphates||4.4.3. and 4.4.4.||1501.10|
6.1.2. Rate of Solution and Matter Insoluble in Water: A 1.5000 ± .005 g sample is weighed in a 250 ml beaker. Heat 150 ml of distilled water to 115-120 °F. The heated water is added to the detergent with a magnetic stirrer on a stir plate. At the end of three (3) minutes, if there is any insoluble material, the solution is filtered through a tarred filter paper. To insure that all the insoluble residue is transferred to the filter paper, the beaker should be rinsed, onto the filter paper, with less than 20 ml of cool distilled water. The filtrate is then dried at 105 °C to constant weight, and the matter insoluble calculated. The weight of the insoluble matter shall not exceed 0.1 percent.
6.1.3. Optical Brightener: Wet a four (4) inch square cotton swatch with a 0.25 percent by weight solution of the sample, rinse and air dry. Examine swatch under an ultra violet light for fluorescence and brightening effect.
6.1.4. pH: The pH value shall be determined in accordance with ASTM Specification No D-1172.
6.1.5. Foam Height: The foam height shall be tested in accordance with ASTM Specification No. D-1173, using a 0.2 percent solution in water of 50 ppm at 120 °F.
7. INSPECTION: Products furnished under this specification shall be inspected by, or at the direction of the Commission and/or the ordering State agency either at the destination or place of manufacture.
8. PACKING / PACKAGING: Packing for shipment shall be in accordance with the manufacturer's standard practice and in a manner readily accepted by common carriers engaged in interstate commerce.
