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. Standard Taper Stopper Number B. 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. A Lines below the first numbered line may be omitted.

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

It is based on the gravimetric determination of the quantity of water either contained or delivered, and astk conversion of this value to true volume at the standard temperature of 20 o C by means of suitable equations and standard tables. C For Style II, measurement is to bottom of stopper.

Typical products falling within the purview of this practice are burets graduated” to deliver”, graduated cylinders, volumetric flasks, specific gravity flasks, measuring ashm dilution pipets, and transfer and capacity pipets.

Cylinders may be marked with an identification number serial number at the option of the manufacturer. This specification covers the requirements for laboratory glass graduated cylinders for precision and general purpose grades.

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

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. Calibration using mercury is excluded. Calibration using mercury is excluded.

Minimum Wall Thick- ness, mm. If zstm graduations are each 5 mL, intermediate graduations do not apply.
