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.

1.1 This specification covers a glass disposable Prothrombin pipet suitable for use in micro techniques for estimation of Prothrombin time.

1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.3 This precautionary statement pertains only to the test method portion, Section 8, of this specification. This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
