8.    Provide recommended field application rates (e.g., dilution, pretreatment technique, and application technique).

 

9.    Explain how the new product fulfills an existing need or added value to our current Iowa DOT’s winter chemical toolkit.

 

10.  References and contact information for agencies currently using the product.

No product shall be submitted unless it is at least 70% less corrosive than sodium chloride (excluding additives to salt brine) using the National Association of Corrosion Engineers (NACE) Standard TM-01-69 (1995 rev.), modified to use 30ml of a 3% chemical product solution per square inch of coupon surface area. Test data and certification that the material meets corrosion criteria must be included.

 

11.  Lab Samples.

The Iowa DOT requires three- 8 ounce liquid samples or two (2) pounds of the dry chemical samples that must be submitted to the Iowa DOT’s Central Materials Laboratory. The samples must be clearly labeled and a copy of the Material Safety Data Sheet and product data sheet should be included.

 

Please use the sample label supplied below on all samples submitted to the Iowa DOT’s Central Materials Lab for testing. The sample label should be filled out and attached to each sample submitted to ensure that your product can be processed upon receipt.
