In most cases, pressure effects can be ignored 4. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend.

ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard.

ASTM E563:02e1

Large chunks of very cold ice added to a bath can produce local temperature depression. Impurities in the water usually lower the temperature.

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. Users of this standard ashm 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.

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. Allow the bath and vessel to equilibrate for at least 30 minutes before using. It is also intended to be adequate for most other ice-point reference purposes.

As the voice of the U. For this reason surplus water should be removed, as it accumulates, from the bottom of the bath by decanting or siphoning. Temperature differences of 0. Excessive water in the bath can cause an increase in temperature astmm denser warm water settles to the bottom.

The uniformity of temperature of the bath can be enhanced by 5e63 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.

NOTE 1—When liquid-in-glass thermometers are tested in an ice point bath, the bath may be left uncovered. 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.

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.

This standard is not included in any packages. Standards Subsctiption may be the perfect solution. For thermoelectric thermo-elements of high thermal conductivity, as much as mm immersion may be necessary. We have no amendments or corrections for this standard.

This ensures that you are always up-to-date and saves you both time and money. This reduces the time to reach equilibrium at the ice point. 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.

The temperature is lowered by about 6. Cooling helps to preserve the bath at the ice point for prolonged use.

Your comments are invited either for revision of this standard or atm additional standards and should be addressed to ASTM International Headquarters.

Freeze zstm portion of the water to produce ice for the bath.

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 that is suitable for the application.
