This specification covers piston or plunger operated volumetric apparatus (POVA), in particular, the requirements, operating conditions, and test methods. POVA covered by this specification are pipettes, dispensers (with and without valve), dilutors, and displacement burets (with and without valve). Single measurement, replicate delivery, durability, functional (such as tests for leakage, broken parts, existence of air bubbles, and contamination), volumetric, and gravimetric tests shall be performed and shall conform to the requirements specified.
This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.
1.1 This specification covers requirements, operating conditions, and test methods for piston or plunger operated volumetric apparatus (POVA).
1.2 This specification includes specifications applicable for all types of POVA or those given by the manufacturer. The following precautionary caveat pertains only to the test method portion, Section 13, 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.
