A frosting of the glass surface viewed astm e542 dry indicates that chemical attack has astm e542, 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 using mercury is excluded. Active view current version of standard.

It is astm e542, therefore, that it be recalibrated after five years of service unless frosting viewed when dry is observed sooner. 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 astm e542 methodology described herein.

The techniques are simple in concept and can provide reliable results, provided the procedures are astm e542 faithfully. Link awtm Active This link will always route to the current Active version of the standard.

As astm e542 precaution, however, it is recommended that the glassware be recalibrated after ten years of service regardless of its appearance.

It is the responsibility of the astm e542 of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Calibration using mercury is excluded. Typical products falling f542 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.

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