(3) percent. The contractor shall furnish a certified copy of the analysis prior to or with each shipment upon delivery. See Part 8 regarding adjustment of payment based on content H2SiF6.

6. BIDS

7. SUBMITTALS

Prior to contract award, successful bidder shall submit the following documentation for the product to be furnished:

a) Statement naming manufacturer and address (City, State) of the product proposed to be furnished.

b) Proof of ANSI/NSF Standard 60 certification.

c) Data sheet or Certificate of Analysis documenting the product’s concentration (weight percent as H2SiF6), specific gravity of product, free acid, and impurities.

This calculation will be shown on each invoice. Payment will be made on the equivalent tonnage thus calculated.

For example, if the bid price is $300 per ton of 23%W delivered, and 20.5 tons of 21.5%W is delivered, payment would be as follows:

$300 X 20.5 tons X 21.5/23.0 = $5,748.91
