Excessive water in the bath can cause an increase in temperature as denser warm water settles to the bottom.

ASTM E563:02e1

Subscription pricing is determined by: 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 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.

Atsm comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters. Need more than one copy?

A superscript epsilon indicates an editorial change since the last revision or reapproval. Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards.

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. As the voice of the U. Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of e53 rights, are entirely their own responsibility.

For this reason surplus water should be removed, as it accumulates, from the bottom of the bath by decanting or siphoning. Shaved ice resembling snow is preferred, but crushed ice is acceptable if the particles are small not exceeding 2 to 3 mm diameter.

The user must test for this condition. This standard is also available to be included in Standards E653. Start Webshop Product catalog Product presentation. 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 the ice-point bath.

The solubility of air in the water is directly proportional to the atmospheric pressure. You need to log in before adding standards to the monitoring service. Add ice particles, and chilled water, as aetm so that the ice slush column always extends to at least 30 mm below the lowest point of the test object.
