In the structural pipe industry, when someone requests assistance with “California Greenbook Testing” they are indicating their interest in chemical exposure tests of pipe materials to determine if those materials are adversely impacted by the test chemicals. Using the language from the California Greenbook 2015 the tests are designed to “determine the physical properties and weight change of specimens of materials used in sewers after exposure to chemical solutions”. As the central element of testing, test specimens are submerged in nine different solutions at various concentrations. Those solutions are sulfuric acid, sodium hydroxide, ammonium hydroxide, nitric acid, ferric chloride, sodium hypochlorite, soap, detergent and a bacteriological solution. The exposure is prolonged and multiple replicates are tested at various intervals extending to 112 days. If the chemical solution changes in concentration beyond limits proscribed in the test, then the solution must be replaced. Two different types of tests are required – tensile testing and change in weight testing. If the changes in tensile properties or weight go beyond the limits in the test, then the specimen is said to fail. Otherwise, the samples pass. These testing protocols require many replicate samples resulting in an expensive testing protocol.
Our consulting firm provides value to such so called “Pickle Jar” test in several ways. We provide project oversight and assistance in the preparation of the required samples for testing. We also have experience in purchasing the testing required by Section 211-2 of the California Greenbook. Finally, our firm can author a technical report providing a testing narrative along with the results of testing.
