ABSTRACT
Ensure that the zero position of the needle is noted, then quickly release the needle -holder for the specified period of time. If the container moves, ignore the determination; otherwise adjust the instrument as necessary to determine the penetration of the needle into the sample in tenths of a millimetre. If, when the test is carried out outside the bath, the determination is not carried out within 2 minutes, return the test specimen and transfer dish to the bath and repeat the determination.
