ASTM E – 01 Standard Practice for Calibration of Laboratory Volumetric Apparatus

astj A frosting of the glass surface viewed when dry indicates that chemical attack has occured, and recalibration may be in order. As a precaution, however, it is recommended that the glassware be recalibrated after ten years of service regardless of its appearance.

If main graduations are each 5 mL, intermediate graduations do not apply. C For Style II, measurement is to bottom of stopper. Link to Active This link will always route to the current Active version of the standard.

However, volumetric tolerances for Class B cylinders shall e5542 within twice the specified range allowed for Class A cylinders.

A Lines below the first numbered line may be omitted. Calibration using mercury is excluded.

B Applies to Style Asstm only. 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. Minimum Wall Thick- ness, mm. 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, and the conversion of this value to true volume at the standard temperature of 20 o C by means of suitable equations and standard tables.

This abstract is a brief summary of the referenced standard. 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.

Cylinders may be marked with an identification number serial number at the option of the manufacturer.

These cylinders need not be marked with their class designation. It is informational only and not an official part of the standard; the full text of ast, standard itself must be referred to for its use and application.

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. Historical Version s – view previous versions of standard.

D Main graduations may be each 5 or 10 mL. Active view current version of standard. Standard Taper Stopper Number B. 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. The products should conform to the required cylinder and base shapes, dimensions, quality of gradation and identification markings, and length of gradation lines.

This specification covers the requirements for laboratory glass graduated cylinders for precision and general purpose grades. The graduated cylinders may be in one of three styles; beaded lip with spout, grounded standard taper neck, or beaded lip with pour spout and reinforcing band near the top.
