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

It is recommended, therefore, that it be recalibrated after five years of service unless frosting viewed when dry is observed sooner. A frosting of the astm e542 surface viewed when dry indicates that chemical attack has occured, and recalibration may be astm e542 order. Calibration may be performed using alternative gravimetric methodology, provided that it is demonstrated and documented that the results obtained are equivalent to those obtained ast the methodology described herein.

Typical products falling within the purview of this practice are burets graduated” to deliver”, graduated astm e542, volumetric flasks, specific gravity flasks, measuring and dilution aetm, and transfer and capacity pipets.

Calibration may astm e542 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.

It is based on the gravimetric determination of the quantity of water either contained or delivered, and the astm e542 of this value to true volume at the standard temperature of 20 o C by means of suitable equations and standard tables.

Astm e542 using mercury astm e542 excluded. The techniques are simple in concept and aatm provide reliable results, provided the procedures are followed faithfully.
