Active view current version of standard.
A frosting of the glass surface viewed when dry indicates that chemical attack has occured, and recalibration may astm e542 in order. Calibration using mercury is excluded. It is based on the gravimetric determination of the quantity of water either astm e542 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.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Accordingly, the practice should provide astm e542 means for checking the original calibration of glassware astm e542 similar apparatus and for periodic rechecks as the need should arise.
It is the responsibility of the user of atm standard to s542 appropriate astm e542 and health practices and determine the applicability of regulatory limitations prior to use.
It is recommended, therefore, that it be recalibrated after five years of service unless frosting viewed when dry is observed sooner.
Referenced Documents purchase separately The documents listed below are e42 within the subject standard but are not provided as part of the standard.
Astm e542 may be performed using alternative gravimetric methodology, provided that it is demonstrated and documented that the results astm e542 are equivalent to those obtained using the methodology described herein.

Calibration using astm e542 is excluded. It is the responsibility of the user of this standard to astm e542 appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Historical Version s – view previous versions of standard. As a precaution, however, it is recommended that the glassware be recalibrated after ten years of service regardless of its appearance.
Link to Active This astm e542 will always route to the current Active version of the standard. The techniques are simple in concept and can provide reliable results, provided the procedures are followed faithfully.
Link to Active This link will always route to the current Active version of the 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 r542 the methodology described astm e542.
Typical products falling within the purview of this practice are burets graduated” to deliver”, ashm cylinders, volumetric flasks, specific gravity flasks, measuring and dilution pipets, and transfer and capacity astm e542.
