*pbw: percent by weight

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: Measure by the procedure of ASTM E 70 except that a 1% solution shall be used. Determine compliance with Table 2.

6.1.2. Alcohol-Insoluble Matter: Measure by the procedure of ASTM D 1568. Determine compliance with Table 2.

6.1.3. Water-Insoluble Matter: Measure by the procedure of ASTM D 1568, Section 142-144. Determine compliance with Table 2.

6.1.4. Total Alkalinity: Measure total alkalinity as Na2O by the procedure of ASTM D 501, Section 69-73. Determine compliance with Table 2.

6.1.5. Foam Height: Measure as follows: Take 10.0 ml of the 1.0% solution used for the pH test, dilute with dionized water to 50.0 ml, and transfer to a 250 ml graduated cylinder. Stopper the cylinder and shake by inversion, rotating the cylinder about its midpoint without transitional motion for one minute at such a rate that 30 inversions are completed. Place the cylinder in an upright position upon a rigid surface, remove the stopper, wait five seconds and read the net volume of foam (total volume minus the volume of the liquid). Determine compliance with Table 2.

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. Within the shipping carton, units shall be packed in a manner designed to minimize damage during the shipment because of rough or improper handling.

8.1. PACKING: The product shall be packaged in boxes of 5 pounds net weight, 10 boxes per case, or in sturdy, well made drums of approximately 100 pounds net weight. The material of the box or drum shall neither affect, nor be affected, by the contents for a period of six months from date of shipment.


9.1. MARKING: Each shipping container shall be clearly marked with the following:

9.1.1. Name of contents.

9.1.2. Quantity contained.

9.1.3. Name and address of the manufacturer.
