(Specification)Standard Specification for Blood Sedimentation Tube, Wintrobe, Glass, Disposable
Standard Specification for Blood Sedimentation Tube, Wintrobe, Glass, Disposable
ABSTRACT
This specification covers disposable blood sedimentation tubes suitable for determining sedimentation rates and the volume of packed red blood cells. This specification covers a tube intended for one-time use only. The tubes shall be fabricated borosilicate glass, Type I, Class B, or from soda lime glass, Type II. The tubes shall be tested for their marking permanency and resistance to centrifugal test.
SCOPE
1.1 This specification covers disposable blood sedimentation tubes suitable for determining sedimentation rates and the volume of packed red blood cells.
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 The following precautionary statement pertains only to the test method portion, Section 7 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
