ASTM E563 – 11(2016)
NOTE 1—When liquid-in-glass thermometers are tested in an ice point bath, the bath may be left uncovered. Your Alert Profile d563 the documents that will be monitored. You can download and open this file to your own computer but DRM prevents opening this file on another computer, including a networked server.
Excessive water in the bath can cause an increase in temperature as denser warm water settles to the bottom.
Discontinued February and reinstated as E — Use clean plastic gloves to handle the ice and equipment. Current edition approved Nov. Please first log in with a verified email before subscribing to alerts. If you need to be able to add standards to qstm monitoring service, you must register as a user with your own username and password.
The temperature increase depends on the electric power being dissipated and the thermal resistance between the sensor and the water-ice interface. The loss of f563 between a covered and uncovered bath may be below the resolution of liquid-in-glass thermometers. For usual applications, a diameter of at least 70 mm and a depth of at least mm may be adequate.
Use an opaque and thermally insulating cover or stopper that is suitable for the application. As ice melts, the interface moves away from the test object, and a temperature difference, which can wstm as much as several kelvins, is established between the test object and the heat sink.

This service is not available if you are a URL user where you do not log in with an email address. A water-ice interface in astk bath acts as a heat sink. Because it may not be technically possible to adequately depict all changes accurately, ASTM w563 that users consult e536 editions as appropriate. Originally published as E — The benefits of a subscription: Add to Alert PDF.
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. For partial immersion liquid-in-glass thermometers, immerse to the immersion line or stated immersion depth.
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. As the voice of the U. The moment new editions of the standards you monitor are released, changes are made, or appendixes asmt published, you will be alerted by email.
Freeze another portion of the water to produce ice for the bath. 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. Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility.
Shaved ice resembling snow is preferred, but crushed ice is acceptable if the particles are small not exceeding 2 to 3 mm diameter. Temperature differences of 0.
Precision and Bias 8. In all cases only the current version of the standard as published by ASTM is to be considered the official document. Please first verify your email before subscribing to alerts.
The solubility of air in the water is directly proportional to the atmospheric pressure. Standards Subsctiption may be the perfect solution. Large chunks of very cold ice added to a bath can produce local temperature depression.
