标准简介
适用范围:
This specification covers the general and design requirements for two types of cell-type ovens based on their rates of ventilation, for determining loss in weight or changes in properties of materials on heating at elevated temperatures. This specification takes into account the fact that chamber geometry, rate of ventilation, and temperature each affect the rate of loss of volatile constituents from a material, or the rate of change in other properties. Hence, this oven is recommended whenever the results are dependent on the time and temperature of heating, the amount of ventilation, or both.1.1 This specification covers the general requirements of a cell-type oven with controlled rates of ventilation for determining loss in weight or changes in properties of materials on heating at elevated temperatures. These specifications take into account the fact that chamber geometry, rate of ventilation, and temperature each affect the rate of loss of volatile constituents from a material, or the rate of change in other properties. This oven is recommended whenever the results are dependent on the time and temperature of heating, the amount of ventilation, or both. It is assumed that specific requirements such as specimen shape and dimensions, rate of ventilation, time, and temperature will be included in the applicable material specifications or test methods.NOTE 1: Ovens meeting these specifications have been found useful for determination of plasticizer loss in plastics, and for controlled aging of elastomers and plastics.1.2 The values stated in inch-pound units are to be regarded as the standard.1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
