Exhibit D - C of C for New Plastic Materials.docx

This is a Certificate of Compliance document for new plastic media required under the Abrasive Blast Media Lease and Recycling Service contract opportunity for the State of Maine. The subcontractor must provide written test data accompanying all deliveries of new plastic media; materials received without the required certificate will be rejected. The specification establishes standards for plastic media products, such as those conforming to MIL-P-85891A Type II Urea Formaldehyde, and requires documentation of lot or batch numbers with each finished lot defined as a minimum of 1 drum (250 pounds) up to a maximum of 10,000 pounds.

The certificate requires the subcontractor to submit comprehensive test data for each lot of plastic media, including Barcol hardness measurements, infrared spectrograms, ash content analysis, specific gravity measurements, pH levels, conductivity readings, heavy particles analysis, and sieve size determinations. These quality assurance requirements ensure that all new plastic media supplied under the contract meets established material specifications and performance standards for abrasive blast media applications.
