There is a ee563 effect for changes in atmospheric pressure. The uniformity of temperature of the bath can be enhanced by slowly stirring or aetm 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. Use clean plastic gloves to handle the ice and equipment. A superscript epsilon indicates an editorial change since the last revision or reapproval.

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 ice-point bath.

This ensures that you are always up-to-date and saves you both time and money. Add to Alert PDF. A water-ice interface in the bath acts as a heat sink. The temperature increase depends on the electric power being dissipated and the thermal resistance between the sensor and the water-ice interface. Large chunks of very cold ice added to a bath can produce local temperature depression.

Webprint Printed and bound.

In all cases only the current version of the standard as published by ASTM is to be considered the official document. Excessive water in the bath can cause an increase in temperature as sstm warm water settles to the bottom.

Temperature differences of 0. Already Subscribed to this document. Shaved ice resembling snow is preferred, but crushed ice is acceptable if the particles are small not exceeding 2 to 3 mm diameter. Thoroughly rinse the equipment with tap water, then rinse with the type of water used for the ice-point bath medium. For partial immersion liquid-in-glass thermometers, immerse to the immersion line or stated immersion depth.

Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. The user must test for this condition. Freeze another portion of the water to produce ice for the bath. Start Webshop Product catalog Product presentation.

The loss of precision between a covered and uncovered bath may be below the resolution of liquid-in-glass thermometers. 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.

For this reason surplus water should be removed, as it accumulates, from the bottom of the bath by decanting or siphoning. Also, some of the water may freeze and bridge some of the particles.

For usual applications, a diameter of at least 70 mm and a depth of at least mm may be adequate. It is also intended to be adequate for most other ice-point reference purposes. Allow the bath and vessel to equilibrate for at least 30 minutes before using.
