Errors in exposure are cumulative with time. This standard and ISO address the same subject matter but differ in technical content.

It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. If the document is revised or amended, you will be notified by email. Already Subscribed to this document.

Recommended procedures for determining the thermal aging characteristics of a material using a series of elevated temperatures for the purpose of estimating endurance time to a defined property change at a lower temperature are also described; the applicability of the Arrhenius relation for making predictions to other temperatures, is assumed in this case.

Therefore, for any application of the CUT or the TI temperature index to be valid, either the thermal aging program must duplicate the intended thermal exposure conditions of the end product, or the Arrhenius relation must apply.

This standard is also available to be included in Standards Subscriptions. Caution should be exercised aastm using the Arrhenius relation and knowledge of physical changes in the material at elevated temperatures is important. The effect of elevated temperature on any particular property is determined by selection of the appropriate test asttm and test specimens for that property. Subscription pricing is determined d305 Only the procedure for heat exposure is specified.

Recommended procedures for determining the thermal aging characteristics of a material using a series of elevated temperatures for the purpose of estimating endurance time to a defined property change at a lower temperature are also described; the applicability d0345 the Arrhenius relation for making predictions to other temperatures, is assumed in this case. We have no amendments or corrections for this standard.

The effect of elevated temperature on any particular property is determined by selection of the appropriate test method and test specimens for that property.

A plastic material is not necessarily degraded by exposure to elevated temperatures. The property of interest is measured at room temperature.

However, the data obtained from this practice, since it does not account for the influence of stress or environment that is involved in most real life applications, must be used cautiously by the designer, who must inevitably make material choices using additional data such as creep and creep rupture that are consistent with the requirements of the specific application.

The property of interest is measured at room temperature. Work Item s – proposed revisions of this standard. These transitions should be avoided both in the range of aging temperatures used, as well as in extrapolation of the lifeline. Please first verify your email before subscribing to alerts. However, extended periods of exposure of plastics to elevated temperatures will generally cause some degradation, with progressive changes in physical properties. Normally, additional shrinkage should be expected with loss of volatiles or advance in polymerization.

Add to Alert PDF. The severity of the exposures in both time and temperature determines the extent and type of change that takes place. Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards. Other types of plastics become soft and sticky, either due to sorption of volatilized plasticizer or due to breakdown of the polymer. As the voice of the U. Different properties, mechanical or electrical, may not change at the same rate.

Specific properties and failure or lifetime criteria for these properties are typically chosen for the evaluation of thermal endurance. Arrhenius principles may only be used to accelerate a chemical mechanism if there are no fundamental changes in the material properties.

Factors that affect the reproducibility of data are the degree of temperature control of the enclosure, humidity of the oven, air velocity over the specimen, and period of exposure.
