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

6 .1.1. Anionic Synthetic Surfactant: A minimum of 11.2% activity shall be determined by ASTM D 1681.

6.1.2. Sodium Tripolyphosphate: A minimum of 5.0% P2O5 shall be determined by AOCS Da 20a.

6.1.3. Sodium Sesquicarbonate: A maximum of 26.2% CO2 shall be determined by AOCS Da 19B.

6.1.4. Sequestering Agent: A minimum of 1.44% disodium salt of E.D.T.A. shall be determined by ASTM D 1767.

6.1.5. pH: The pH shall be tested by ASTM D 1172.

6.1.6. Sequestering Ability: Dilute one part by weight of the washing compound with 50 parts of water having a hardness of 500 parts per million as calcium carbonate and allow to stand for ten (10) minutes. Upon careful examination, the solution must remain homogeneous and stable throughout this period. To prepare 500 ppm hard water, dissolve 0.580 grams of CaCl2.2 H2O and 0.259 grams of MgSO4.7 H2O in enough distilled water to bring the final volume to one liter.
