ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard. Summary of Practice ast. Need more than one copy? Originally published as E — NOTE 1—When liquid-in-glass thermometers are tested in an ice point bath, the bath may be left uncovered.

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. Subscription – always available and updated A web subscription provides an easy and secure access to standards, and you are guaranteed to always have the latest edition. This reduces the time to reach equilibrium at the ice point. The temperature is lowered by about 6. Use clean plastic gloves to handle the ice and equipment.

Cooling helps to preserve the bath at the ice point for prolonged use. This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version.

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 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.

Allow the bath and vessel to equilibrate for at least 30 minutes before using. The moment new editions of the standards you monitor are released, changes are made, or appendixes are published, you will be alerted by email. There is a corresponding effect for changes in atmospheric pressure.

It is also intended to be adequate for most other ice-point reference purposes. Shaved ice resembling snow is preferred, but crushed ice is acceptable if the particles are small not exceeding 2 to 3 mm diameter.

The solubility of air in the water is directly proportional to the atmospheric pressure. Standards Subsctiption may be the perfect solution. Because it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate.

Discontinued February and reinstated as E — The loss of precision between a covered and uncovered bath may be below the resolution of liquid-in-glass thermometers. Proceed to Checkout Continue Shopping.

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. Large chunks of very cold ice added to a bath can produce local temperature depression. This service is not available if you are a URL user where you do not log in with an email address.
