1.1 本规范涵盖了具有受控通风速率的电池式烘箱的一般要求，以确定在高温下加热时材料的重量损失或性能变化。这些规范考虑了这样一个事实，即腔室几何形状、通风速率和温度都会影响材料中挥发性成分的损失速率或其他特性的变化速率。当结果取决于加热时间和温度、通风量或两者时，建议使用该烤箱。假设适用的材料规范或试验方法中包含具体要求，如试样形状和尺寸、通风速率、时间和温度。 注1: 符合这些规范的烘箱对于测定塑料中的增塑剂损失以及控制弹性体和塑料的老化非常有用。 1.2 以英寸-磅为单位的数值应视为标准值。 1.3 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。

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.
