The uniformity of temperature of the bath can be enhanced by slowly stirring or agitating the slush of ice and water either manually or by a powered stirring means so that all of the ice and water in the bath come into intimate contact. This reduces the time to reach equilibrium at the ice point. This standard is also available to be included in Standards Subscriptions. Originally published as E — For partial immersion liquid-in-glass thermometers, immerse to the immersion line or stated immersion depth.

As ice melts, the interface moves away from the test object, and a temperature difference, which can be as much as several kelvins, is established between the test object and the heat sink. The moment new editions of the standards you monitor are qstm, changes are made, or atm are published, you will be alerted by email.
The user must test for this condition. In most cases, pressure effects can be ignored 4. 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. NOTE 1—When liquid-in-glass thermometers are tested in an ice point bath, the bath may be left uncovered. In all cases only the current version of the standard as published by ASTM is to be considered the official document.
Add ice particles, and chilled water, as necessary so that the ice slush column always extends to at least 30 mm below the lowest point of the test object. Already Subscribed to this document.

For this reason surplus water should be removed, as it accumulates, from the bottom of the bath by decanting or siphoning. At steady state conditions, an error results that depends primarily on the thermophysical properties of the object, its dimensions and its depth of immersion in e63 ice-point bath.
Thoroughly rinse the equipment with tap 5e63, then rinse with the type of water used for e5663 ice-point bath medium. Summary of Practice 4.

Use of the bath must be delayed e653 enough to establish thermal equilibrium, and the particles shall be sufficiently small so that the bath approaches the required state of ice e536 air-saturated water in intimate contact.
