2. 2.20 How is an all levels sample obtained?1) 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.
2) b. By blending upper, middle and lower samples from the same tank.
3) 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.
4) 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.
