Specifications include, but are not limited to: Percent Concentration of Active Ingredient in the Liquid: Test Method: Atomic Absorption or Inductively Coupled Plasma Spectrophotometry as described in “Standard Methods for the Examination of Water and Wastewater”, APHA- AWWA-WPCF is acceptable. Test Method “A” in Appendix “A” is used to determine percent concentration of Calcium Chloride or Magnesium Chloride by Atomic Absorption. The operator should be aware that the high solids content of the samples can present special considerations when conducting the analysis. Weight Per Gallon: Test Method: Specific Gravity by ASTM D 1429 Test Method A - Pycnometer at 20℃ ± 1℃ Corrosion Control Inhibitor Presence and Concentration: Test Method: The Materials Laboratory may use the test procedures provided by the vendor or manufacturer for testing quantitative concentrations of additives. These same tests can then be used to verify that materials being delivered are the same as those previously tested and approved in the bid process. pH: Test Method: ASTM D 1293 except a dilution shall be made of 1-part chemical product to 4 parts distilled water before attempting a reading. Corrosion Rate: Test Method: NACE Standard TM0169-95 (1995 Revision) as modified by PNS. This procedure is listed as Test Method “B” in Appendix A of the Clear Roads publication Snow and Ice Control Chemical Products Specifications and Test Protocols Revision 12-10. Publication is found at Clear Roads website clearroads.org under Partnership Projects – Qualified Products List- Chemical Products Specifications and Test Protocols (3/2019) Percent Total Settleable Solids and Percent Solids Passing a 10 Sieve: Test Method: This procedure is listed as Test Method “C” in Appendix A of the Clear Roads publication Snow and Ice Control Chemical Products Specifications and Test Protocols Revision 12-10. Publication is found at Clear Roads website clearroads.org under Partnership Projects – Qualified Products List- Chemical Products Specifications and Test Protocols (3/2019) Total Phosphorus: Test Method: Total Phosphorous as described in “Standard Methods for the examination of Water and Wastewater”, APHA-AWWA-WPCF. Total Arsenic, Barium, Cadmium, Chromium, Copper, Lead, Selenium and Zinc: Test Method: Atomic Absorption Spectrophotometry or Plasma Emission Spectroscopy as described in “Standard Methods for the examination of Water and Wastewater”, APHA-AWWA-WPCF. Note: This will be bid as one group of tests. Total Mercury: Test Method: Cold Vapor Atomic Absorption Spectrophotometry as described in “Standard Methods for the examination of Water and Wastewater”, APHA-AWWA- WPCF.
