Test procedure -- Prototype core sampler
The purpose of this test is to attempt to determine the adequacy of the prototype sampler. Recovery tests will be performed with this sampler in three different consistencies of kaolin sludge simulants. A minimum of six tests will be done in each of the simulants. The sampler is a hollow steel sampling tube with a tapered nose and a retractable point. The point is sealed against the inside wall of the sampler by two O-rings, which keep the waste material from entering the sampler prematurely. When the point is retracted, the biggest O-ring assists in collecting the sample by producing a slight negative pressure within the sampler tube. The sampler can be operated by hand. The concept is similar to, but simpler than, the present WHC rotary valve sampler in that a solid core is recovered and an O-ring piston is used to provide a negative internal pressure to assist sample recovery. The test will be performed in three 55-gallon drums each filled with a kaolin sludge of a different consistency. The drums will contain an approximate depth of 33 inches of sludge. The prototype Concord sampler will attempt to collect 19-inch samples at two distinct depths. No waste tank simulation with full length or any length of the auger shroud equipment will be attempted in this test. A simple locating and clamping tool will be made to facilitate the sampling.
