Sampling equipment shall be made of stainless steel, or other suitable material of adequate strength and of a construction suitable for the intended purpose (mixing, sampling etc.). Plungers and agitators for mixing liquids in containers shall have a sufficient area to produce adequate mixing of the product, but without causing the development of a rancid flavour. Dippers must have a solid handle of sufficient length to enable a sample at any depth of the container to be obtained. The capacity of the dipper shall be not less than 50 ml.
Sample containers and closures should be of glass, suitable metals or plastics.
The materials of which sampling equipment (including containers and closures) is constructed must not cause any change in the sample which could affect the results of the examinations. All surfaces of sampling equipment and sample containers shall be clean and dry, smooth and free from crevices, and corners shall be rounded.
