The temperature increase depends on the electric power being dissipated and the thermal resistance between the sensor and the water-ice interface. Current edition approved Nov.

As the voice of the U. It is also intended to be adequate for most other ice-point reference purposes. Large chunks of very cold ice added to a bath can produce local temperature depression.

Temperature differences of 0. Cooling helps to preserve the bath at the ice point for prolonged use. In all cases only the current version of the standard as published by ASTM is to be considered the official document. A superscript epsilon indicates an editorial change since the last revision or reapproval.

The moment new editions of the standards you monitor are released, changes are made, or appendixes are published, you will be alerted by email. This ensures that you are always up-to-date and saves you both time and money. The user must test for this condition. Freeze another portion of the water to produce ice for the bath.

Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters. The loss of precision between a covered and uncovered bath may be below the resolution of liquid-in-glass thermometers.

Shaved ice resembling snow is preferred, but crushed ice is acceptable if the particles are small not exceeding 2 to 3 mm diameter. Need more than one copy?

The solubility of air in the water is directly proportional to the atmospheric pressure. Monitoring Standards monitoring is a free service designed for you who wish to be alerted of changes to or new editions of the standards required in your work. For thermoelectric thermo-elements of high thermal conductivity, as much as mm immersion may be necessary.

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.

The temperature is lowered by about astn. Also, some of the water may freeze and bridge some of the particles. This document is not an ASTM standard and w563 intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Use an opaque and thermally insulating cover or stopper that is suitable for the application.

Use of the bath must be delayed long enough to establish thermal equilibrium, and the particles shall be sufficiently small so that the bath approaches the required state of ice and ee563 water in intimate contact.

A number in parentheses indicates the year of last reapproval. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine aetm 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.

Add to Alert PDF. 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 ee563 powered stirring means so that all of the atm and water in the bath come into intimate contact. Impurities in the water usually lower the temperature. Precision and Bias 8. This reduces the time to reach equilibrium at the ice point.
