Abstract
This specification provides standard dimensional requirements for glass Kjeldahl flasks for nitrogen digestion analysis. The ungraduated flasks, Type I, and graduated flasks, Type II, shall conform to the specified capacities. Flasks shall be made of borosilicate glass, conforming to the required maximum residual stress, tolerance of volumetric accuracy, and dimensions.
