ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard. Subscription pricing is determined by: Summary of Practice 4. 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 adtm the test object and the heat aastm.
A web subscription provides an easy and secure access to standards, and you are guaranteed to always have the latest edition. The loss of precision between a covered and uncovered bath may be below the resolution of liquid-in-glass thermometers. This ensures that you are always up-to-date and saves you both time and money.

A superscript epsilon indicates an editorial change since the last revision or reapproval.
Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters. 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. Cooling helps to preserve the bath at the ice point for prolonged use.
Norma ASTM E()
The presence of excess water can be detected if water overspill occurs when the ice is depressed. Thoroughly rinse the equipment with tap water, then rinse with the type of water used for the ice-point bath medium. Use clean plastic gloves to handle the ice and equipment. 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 axtm water in the bath come into intimate contact.
Because it may not be technically possible to adequately astmm all changes accurately, ASTM recommends that users consult prior editions as appropriate.
Webprint Printed and bound. The temperature is lowered by about 6. There is a corresponding effect for changes in atmospheric pressure.
This reduces the time to reach equilibrium at the ice point. In most cases, pressure effects can be ignored 4. The user must test for this condition.
Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. Please first verify your email before subscribing to alerts. Shaved ice resembling snow is preferred, but crushed ice is acceptable if the particles are small not exceeding 2 to 3 mm diameter.

Use an opaque and thermally insulating cover or stopper asfm is suitable for the application. Aastm may delete a document from your Alert Profile at any time. If you need to be able to add standards to the monitoring service, you must register as a user with your own username and password. The solubility of air in the water is directly proportional to the atmospheric pressure. Discontinued February and reinstated as E — Originally published as E — 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 asfm of ice and air-saturated water in intimate contact.
As the voice of the U. It is also intended to be adequate for most other ice-point zstm purposes. Proceed to Checkout Continue Shopping.
For partial immersion liquid-in-glass thermometers, immerse to the immersion line or stated immersion depth. 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.
Excessive water in the bath can cause an increase in temperature as denser warm water settles to the bottom. At steady state conditions, an error results that depends primarily on the thermophysical properties of the object, its dimensions and its depth atm immersion in the ice-point bath.

Already Subscribed to this document. 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. If the document is revised or amended, you will be asgm by email. A water-ice interface in the bath acts as a heat sink. Start Webshop Product catalog Product presentation.
