This abstract is a brief summary of the referenced standard. D Main graduations may be each 5 or 10 mL. Calibration using mercury is excluded. C For Style II, measurement is to bottom of stopper. ASTM does not give any warranty express or e52 or make any representation that the contents of this abstract are accurate, complete or up to date. Calibration may be performed using alternative gravimetric methodology, provided that it is demonstrated and documented that the adtm obtained are equivalent to those obtained using the methodology described herein.

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. A frosting of the glass surface viewed when dry indicates that chemical attack has occured, and recalibration may be in order.

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. However, volumetric tolerances for Class B cylinders shall be within twice the specified range allowed for Class A cylinders.

Typical products falling within the purview of this practice are burets graduated” to deliver”, graduated cylinders, volumetric flasks, specific gravity flasks, measuring and dilution pipets, and transfer and capacity pipets. As a precaution, however, it is recommended that the glassware be recalibrated after ten years of service regardless of its appearance.

B Applies to Style II only. If main graduations are each 5 mL, intermediate graduations do not apply. 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. The products should conform to the required cylinder and base shapes, dimensions, quality of gradation and identification markings, and length of gradation lines.

The techniques are simple in concept and can provide reliable results, provided the procedures are followed faithfully. Active view current version of standard.

These cylinders need not be marked with their class designation. Accordingly, the practice should provide a means for checking the original calibration of glassware and similar apparatus and for periodic rechecks as the need should arise.

Calibration may be performed using alternative gravimetric methodology, provided that it is demonstrated and documented that the results obtained are equivalent to those obtained using the methodology described herein. It is based on the gravimetric determination of the quantity of water either contained or delivered, aastm the conversion of this value to true volume at the standard temperature of 20 o C by means of suitable equations and standard tables.

It is recommended, therefore, that it be recalibrated after five years of service unless frosting viewed when dry is observed sooner. Historical Version s – view previous versions of standard.
