6.1. Tests: The product furnished under this specification shall be tested by the following methods or approved equally applicable procedures:

6.1.1. Stability: Determine the stability of the product by testing a 100 gram sample at 120 F for 24 hours. At the end of the time, the liquid shall show no evidence of sedimentation or separation of the components. Determine compliance with Paragraph 5.1.

6.1.2. Total Solids: Measure by the procedure of ASTM D 460; shall be 15.0 percent by weight minimum to 24.0 maximum.

6.1.3. pH: Measure the pH by ASTM E 70. pH shall be 6.5 -- 8.5.

6.1.4. Foam Height: (3% Solution) Weight 0.3 grams of the fire foam into 150 ml beaker; add 9.7 g deionized water and gently stir for one (1) minute. Slowly pour the mixture into a 250 ml glass stoppered graduated cylinder. Stopper the cylinder and agitate the contents by smooth rotation for the cylinder about the midpoint to the inverted position and back again ten (10) times.

Procedure will tank ten to fifteen seconds (10-15 sec.). Remove the stopper. Take the initial reading within five (5) seconds, again after one (1) minute and five (5) minutes. Determine compliance:

5 sec 130 ml height

1 min 125 ml height

5 min 120 ml height

7. SAMPLES: Unless otherwise specified in the Invitation for Bids, no prepurchase samples shall be required. Samples tested shall be taken from regular orders.
