Common use of Construction materials Clause in Contracts

Construction materials. Construc- tion materials and equipment that may contact the stock solution, test solu- tion or dilution water should not con- tain substances that can be leached or dissolved into aqueous solutions in quantities that can alter the test re- sults. Materials and equipment that contact stock or test solutions should be chosen to minimize sorption of test substances. Glass, stainless steel, and perfluorocarbon plastic should be used wherever possible. Concrete, fiberglass, or plastic (e.g., PVC) may be used for holding tanks, acclimation tanks, and water supply systems, but they should be aged prior to use. Rubber, coopper, brass, galvanized metal, and lead should not come in contact with the di- lution water, stock solution, or test so- lution.
