These cylinders need not be marked with their class designation. Minimum Wall Thick- ness, mm. The products should conform to the required cylinder and base shapes, dimensions, quality of gradation and identification markings, aetm length of gradation lines.

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

It is recommended, therefore, that it be recalibrated after five years of service unless frosting viewed when dry is observed sooner. 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.

D Main graduations may be each 5 or 10 mL. A Lines below the first numbered line may be omitted. Active view current version of 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.

Distance From Scale to Top, mm. 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. 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.

Asttm, 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.

ASTM E – 02() Standard Specification for Laboratory Glass Graduated Cylinders

If main graduations are each 5 mL, intermediate graduations do not apply. The techniques are simple in concept and can provide reliable results, provided the procedures are followed faithfully. Calibration may be performed using alternative astn methodology, provided that it is demonstrated and documented that the results obtained are equivalent to those obtained using the methodology described herein.

As a precaution, however, it is recommended that the glassware be recalibrated after ten years of service regardless of its appearance.

This specification covers the requirements for laboratory glass graduated cylinders for precision and general purpose grades. Calibration using mercury is excluded. Historical Version s – view previous versions of standard. 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.

C For Style II, measurement is to bottom of stopper. Standard Taper Stopper Number B. 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.

However, volumetric tolerances for Class B cylinders shall be within twice the specified range allowed for Class A cylinders. 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. Maximum Inner Diameter, mm. Historical Version s – view previous versions of standard. 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. Cylinders may be marked with sstm identification number serial number at the option of the manufacturer.

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