This International Standard specifies a general method for the determination of crystallizing points in the range from about - 50 to about 250 °C. The crystallizing point can be determined directly on the sample as received, or on the dried sample, or on both. In which of these conditions the sample is to be tested and, if the determination is to be made with the dried sample, what method of drying is to be used, will be stated in the specific test method for each material.
