1. 2.20 How is an all levels sample obtained? a. By submerging an unstoppered sampler to a point near the tank draw-off outlet (suction) level and then raising it, all at a uniform rate, so that it is no more than 85% full on emerging from the liquid. b. By blending upper, middle and lower samples from the same tank. c. By submerging a stoppered sampler to a point as near as possible to the draw-off outlet (suction) level, then opening the sampler and raising it at a rate such that it is no more than 80% full as it emerges from the liquid. d. By submerging a stoppered sampler to the mid point of the product in a tank, then opening the sampler and raising and lowering it at a uniform rate until the sampler is full. 2. 2.21 How is a running sample obtained? a. by lowering an unstoppered sampler from the top of the oil to the level of the outlet (Suction) and returning it to the top of the oil at a uniform rate so that the sampler is no more than 85% full when withdrawn from the oil. b. by lowering a stoppered sampler to the level of the outlet, then opening the sampler and raising it at a uniform rate so that it is about 80% full when withdrawn from the oil. c. by lowering a stoppered sampler to the mid point of the tank contents, then opening the sampler and raising and lowering it at a uniform rate until it is full d. by lowering an unstoppered sampler to the mid point of the tank contents, then raising and lowering it at a uniform rate until it is full 3. 2.22 What is a floating roof tank? a.
