Allow the bath and vessel to equilibrate for at least 30 minutes before using. The temperature increase depends on the electric power being dissipated and the thermal resistance between the sensor and the water-ice interface.
The presence of excess water can be detected if water overspill occurs when the ice is depressed.
ASTM E563 – 11(2016)
The solubility of air in the water is directly proportional to the atmospheric pressure. 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. Excessive water in the bath can cause an increase in temperature as denser warm water settles to asfm bottom.
This standard is not included in any packages. We have no amendments or corrections for this standard. This standard is also available to be included in Standards E5633. This service is not available if you are a URL user where you do not log in with an email address.

Users of this standard are expressly advised that determination of the validity of asrm such patent rights, and the risk of infringement of such rights, are entirely their own responsibility.
The user must test for this condition. In most cases, pressure effects can be ignored 4. If you feel that your comments have not received a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below.
The uniformity of temperature of the bath can be enhanced by slowly stirring aatm 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. Shaved ice resembling snow is preferred, but crushed ice is acceptable if the particles are small not exceeding 2 to 3 mm diameter.
A superscript epsilon indicates an editorial change since the last revision or reapproval. The loss of precision between a covered and uncovered bath may be below the resolution of liquid-in-glass thermometers. For partial immersion liquid-in-glass thermometers, immerse to the immersion line or stated immersion depth. Also, some of the water may freeze and bridge some of the particles. Subscription pricing is determined by: Cooling helps to preserve the bath at the ice point for prolonged use. Impurities in the water usually lower the temperature.
Add to Alert PDF. Precision and Bias 8. Temperature differences of 0. NOTE 1—When liquid-in-glass thermometers are tested in an ice point bath, the bath may be left uncovered. 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. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend.

For this reason surplus water should be removed, as it accumulates, from the bottom of the bath by decanting or siphoning. Add ice particles, and chilled water, as necessary so that ast, ice slush column always extends to at least 30 mm below the lowest point of the test object. Use clean plastic gloves to handle the ice and equipment. A number in parentheses indicates the year of last reapproval.
It is also intended to be adequate for most other ice-point reference purposes. Discontinued February and reinstated as E —
