4.3. pH in 5% solution: When one volume of concentrate is diluted to twenty (20) volumes with distilled water and tested in accordance with Paragraph 6., the pH of the resulting solution shall lie in the range of 11.2 -- 11.6.

4.4. Total Solids: The product shall have a total solids content not lower than 17.0 percentage by weight, when tested by the procedure of Paragraph 6.

4.5. Freeze Thaw Stability: The product shall retain a clear and homogeneous appearance when tested by the procedure of Paragraph 6.

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 equally applicable procedures:

6 .1.1. pH in 5% Solution: Prepare a 5% by volume solution of the concentrate in distilled water as described in Paragraph 4.3. Determine pH by the procedure of ASTM E 70.

6 .1.2. Total Solids : Accurately weigh a five (5) gram sample into an evaporating dish, and heat to constant weight in an oven held at 105 1 C. Calculate percent by weight of the sample remaining after evaporation of volatile matter.
