This specification covers the physical requirements and corresponding test methods for disposable glass Prothrombin pipets suitable for use in micro techniques for estimating Prothrombin time. The pipet shall be made of Type 1, Class B borosilicate glass, or Type 2 soda lime glass. The physical properties to which the pipets should adhere to are those for design, dimensions, capacity (accuracy and coefficient of variation), graduation lines, pipet nomenclature, blow-out delivery, color coding, marking permanency, and lot control.
