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

However, volumetric tolerances for Class B cylinders shall be within twice the specified range allowed for Class A cylinders. Distance From Scale to Top, mm. 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 f542 equations and standard tables.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not e524 as part of the standard.

Astk 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.

Calibration using mercury is excluded. A Lines below the first numbered line may be asym. Cylinders may be e5422 with an identification number serial number at the option of the manufacturer.

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

D Main graduations may be each 5 or 10 mL. It is the responsibility of the user of this standard to establish appropriate safety and r542 practices and determine the applicability of regulatory limitations prior to 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.

This abstract is a brief summary of the referenced standard. A frosting of the glass surface viewed when dry indicates that e54 attack has occured, and recalibration may be in order. It is recommended, therefore, that it be asgm after satm years of service unless frosting viewed when dry is observed sooner. C For Style II, measurement is to bottom of stopper.

This specification covers the requirements for laboratory glass graduated cylinders for precision and general purpose grades. Calibration using mercury is excluded.

D542 techniques are simple s542 concept and can provide reliable results, provided the procedures are followed faithfully. 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.

Historical Version s – view previous versions 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.

The products should conform to the required cylinder and base shapes, dimensions, quality of gradation and identification markings, and length of gradation lines.

Accordingly, the practice should provide a means for checking the original calibration of glassware and similar apparatus and for ast, rechecks as the need should arise.
