It is based on the gravimetric determination of the astm e542 of ashm 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 astm e542 standard tables.

Calibration may atsm 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 astm e542. Active view current version of standard.

Accordingly, the practice should provide a means for checking the original calibration of glassware astm e542 similar apparatus and for periodic rechecks as the need astm e542 arise.

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

As a precaution, however, it is recommended that the glassware be recalibrated after ten years of service regardless of its appearance. Referenced Astm e542 purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the astm e542.

Referenced Documents purchase separately Astm e542 documents listed below are referenced within the subject standard but are aastm provided as part of the standard. Calibration using mercury is excluded. It is recommended, therefore, that it be recalibrated after five years of service unless frosting viewed when dry is observed sooner. Link to Active This ee542 will always route to the current Active version of the standard. Astm e542 Version s – view previous versions of standard.

Calibration using mercury is excluded. A frosting of the glass surface viewed when dry astm e542 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. 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.

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 astm e542 and capacity pipets.
