This article establishes procedures for inspecting and sampling liquid calcium chloride. The requirements are set forth in the bid request issued by MoDOT.
1125.1 Apparatus
Sample containers for submitting samples to the Laboratory shall be one-gallon (4 liter) plastic jugs. All containers and equipment shall be clean, dry, and free of all contaminants.
1125.2 Procedure
Each initial shipment per supplier per district on a purchase order shall be sampled and submitted to the Laboratory for testing of chloride content.
Additional shipments shall be sampled for chloride content at minimum rate of 1 sample per 200 tons (180 mg) per supplier per district, approximately 200 gallons per ton (830 liters per mg).
Sampling. A sample shall consist of approximately 1 gallon (4 liters) taken at the point of manufacture, intermediate storage, from the truck at delivery, or from the receiving tank.
The sample to be submitted to the Laboratory shall consist of approximately one gallon (4 liters) of material in a plastic jug.
1125.3 Report
Liquid calcium chloride sampled and submitted to the Laboratory will be reported in accordance with 1125.4 Laboratory Testing Guidelines. A copy of the certification statement as required by the specifications shall accompany the sample to the Laboratory.
Use SiteManager field reporting of liquid calcium chloride. All field reports shall include the Laboratory number under which the chemical composition was tested and accepted as well as invoice or load number and the quantities being reported. Material not sampled may be accepted on the basis of certifications and other field inspection. The report is to indicate acceptance, or rejection. Appropriate remarks, as described in EPG 106.9 Reporting Test Results, are to be included in the report to clarify conditions of acceptance or rejection. All shipments are to be reported by the district.
1125.4 Laboratory Testing Guidelines
This article establishes procedures for Laboratory testing and reporting samples of liquid calcium chloride for use as a deicer. The requirements are set forth in the bid request issued by MoDOT.
1125.4.1 Procedure
Chemical analysis of liquid calcium chloride shall be conducted in accordance with 106.7.48 TM-48, Determination of the Purity of Calcium Chloride. Original test data and calculations shall be recorded in Laboratory workbooks. Test results shall then be recorded through SiteManager.
1125.4.2 Sample Record
The sample record shall be completed in SiteManager, as described in Automation Section 3510, and shall indicate acceptance, qualified acceptance, or rejection. Appropriate remarks, as described in EPG 106.9 Reporting Test Results, are to be included in the remarks to clarify conditions of acceptance or rejection. Test results shall be reported on the appropriate templates under the Tests tab.
