the resistance of a fluid to shear forces, and hence to flow
that property of semifluids, fluids, and gases by virtue of which they resist an instantaneous change of shape or arrangement of parts. It is the cause of fluid friction whenever adjacent layers of fluid move with relation to each other.
The tolerable negative error in the contents of a prepackage is fixed in accordance with the table below, in which products are divided into two classes ("A" and "B"), as set out in 2.5 and 2.6 below, according to their physical characteristics and/or the packaging processes which they undergo and the values of the nominal quantities. ...
The following shall also be considered as belonging to Class "B":
(a) liquid products,
(b) prepackaged products of a nominal weight or volume less than 25 g or 25 ml,
(c) products with rheological properties (e.g. fluidity or viscosity) or density when flowing which cannot be kept sufficiently constant by appropriate technical means.
