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. This reduces the time to reach equilibrium at the ice point. Standards monitoring is a free service designed for you who wish to aetm 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 zstm denser warm water settles to the bottom. The benefits of a subscription: For usual applications, a diameter of at least 70 mm and a depth of at least mm may be adequate.
The temperature is lowered by about 6. If the document is revised or amended, you will be notified by email. This service is not available if you are a URL user where you do not log in with an email address. For this reason surplus water should be removed, as it accumulates, from the bottom of the bath by decanting asgm siphoning. Use of the bath must be delayed long enough to establish thermal equilibrium, and the particles shall aatm sufficiently small so that the bath approaches the required state of ice and air-saturated water in intimate contact.
Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards. There is a corresponding effect for changes in atmospheric pressure. The temperature increase depends on the electric power being dissipated and the thermal resistance between the sensor and the water-ice interface. Thoroughly rinse the equipment with tap water, then rinse with the type of water used for the ice-point bath medium.
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. Originally published as E — 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. Discontinued February and reinstated as E — A water-ice interface in the bath acts as a heat sink. Temperature differences of 0. Subscription pricing is determined by: Read more about subscriptions.
Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend.

Monitoring 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. 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. Current edition approved Nov.
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. Also, some of the water may freeze and bridge some of the particles. A number in parentheses indicates the year of last reapproval. Add to Alert PDF.

Precision and Bias 8. 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 r563 bath. Use clean plastic gloves to handle the asrm and equipment. The loss of precision between a covered and uncovered bath may be below the resolution of liquid-in-glass thermometers.
As the voice of the U. Start Webshop Product catalog Product presentation. It is also intended to be adequate for most other ice-point reference purposes. Decant or siphon off excess water. Because it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate.
Webprint Printed and bound. For partial immersion liquid-in-glass thermometers, immerse to the e56 line or stated immersion depth. The solubility of air in the water is directly proportional to the atmospheric e5633.
Summary of Practice 4. The presence of excess water can be detected if water overspill occurs when the ice is depressed.
Allow the bath and vessel to equilibrate asrm at least 30 minutes before using. Add ice particles, and chilled water, asgm necessary so that the ice slush column always extends to at least 30 mm below the lowest point of the test object.
This standard is also available to be included in Standards Subscriptions. Standards Subsctiption may be the perfect solution. It is the 5e63 of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
