B1.—This standard defines the different sample extraction systems both in the field, in the ginnery or in the factory, before beginning the process in the opening room, in order to subject them to tests to determine their properties. and characteristics. B2.— This method deals with the 4 successive stages for the reduction of the source sample to the convenient size to be used in fiber testing. These stages are convenient to reduce the portions of cotton that must be used in the different operations to which they must be carried out. be subject. It is generally advantageous to go through all of these operations, but there are some cases in which it is preferable to omit one or both of the intermediate operations. B3.— This standard does not deal with the preparation of the test specimens which will be conditioned in accordance with the procedures specified in the test methods for each of the fiber properties.
