Laboratory glassware — Principles of design and construction of volumetric glassware
Reference temperatur, volumetric accuracy, methods of verification and construction are considered. The annexes deal with the limits of volumetric error in relation to capacity and to the diameter at the meniscus. The interrelation between standard deviation, limit of volumetric error, and line thickness is described.
