Purchasing specifications shipment sampling

REPKesentafciyg tat Sawles and Analyses- Suppliers of catalyst and fixed bed adsorbent are being requested to supply representative lot samples and analytical certificates for each nev purchase order at the time the catalyst is ready for shipment. The analytical results are being compared with updated purchase specifications. 

Workers at The Solution Makers noticed that recent shipments of solid iron (III) chloride and solid nickel (II) chloride purchased from ICCNA to make 1000 ppm solutions of iron and nickel appeared to be a slightly different color compared to the same chemicals purchased earlier. When they prepared the solutions, they too appeared to be a slightly different color compared to solutions prepared earlier. They are suspicious that these chemicals are out-of spec (meaning they do not meet the specifications required by law) due to a contaminant. Before they start pointing fingers and say that ICCNA s chemicals are out-of-spec, however, they would like to have an independent analysis done by our laboratory. The contract does not call for us to identify a contaminant. Our purpose is to simply discover whether or not there is, in fact, a colored contaminant present. The Solution Makers have given us samples of both the clean iron (III) chloride and nickel (II) chloride and also the chemicals suspected of being contaminated. 

It is best to request manufacturers to submit samples and to have these tested before selecting a supplier. Any poor test results should he discussed with the manufacturer. A desirable (or acceptable) performance specification should then be included in the purchase order. Samples of the final shipment should he retested to en-sme compliance with the specification. 

Upon request of the purchaser in the contract or order, a manufacturer s report shall be furnished at e time of shipment stating the results of tests made on samples of the material taken during production or transfer and certifying that the cement conforms to applicable requirements of this specification.
