This standard is also available to be included in Standards Subscriptions. Add ice particles, and chilled water, as necessary so that the ice slush column always extends to at least 30 mm below the lowest asym of the test object.
Your Alert Profile lists the documents that will be monitored. Use an opaque and thermally insulating cover or stopper that is suitable for the application. A superscript epsilon indicates d563 editorial change since the last revision or reapproval. 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.
The loss of axtm between a covered and uncovered bath may be below the resolution of liquid-in-glass thermometers. Decant or siphon off excess water.

In most cases, pressure effects can be ignored 4. Allow the bath and vessel to equilibrate for at least 30 minutes before using. Freeze another portion of the water to produce ice for the bath. For thermoelectric thermo-elements of high thermal conductivity, as much as mm immersion may be necessary. Standards Subsctiption may be the perfect solution.
The moment new editions of the standards you monitor are released, changes are made, or appendixes are published, you will be alerted by email. This ensures that you are always up-to-date and saves you both time and money. The solubility of air in the water is directly proportional to the atmospheric pressure.

Precision and Bias 8.
A number in parentheses indicates the year of last reapproval. For this reason surplus water should be removed, as it qstm, from the bottom of the bath by decanting or siphoning.
Temperature differences of 0. For partial immersion liquid-in-glass thermometers, immerse to the immersion line or stated immersion depth. E653 chunks of very cold ice added to a bath can produce local temperature depression. Webprint Printed and bound. Excessive water in the bath can cause an increase in temperature as denser warm water settles to the bottom.
For usual applications, a diameter of at least 70 mm and a depth of at least mm may be adequate. This standard is not included in any packages. ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard. The temperature is lowered by about 6.
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. 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 state of ice and air-saturated water in intimate contact.
Thoroughly rinse the equipment with tap water, then rinse with the type of water used for the ice-point bath medium. 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. Users of this standard are expressly advised that determination of the validity of any such patent e56, and the risk of infringement of such rights, are entirely their own responsibility.
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. 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 zstm and the heat sink. This service is not available if you atm a URL user where you do not log in with an email address.
Impurities in the water usually lower the temperature. The benefits of a subscription:
