EUROLAB laboratory provides testing and compliance services within the scope of ISO 2578 standard. The ISO 2578 standard, developed by the International Standards Organization (ISO), specifies principles and procedures for evaluating the thermal durability properties of plastics exposed to high temperatures for long periods of time. The thermal aging study is based solely on the change in certain properties resulting from exposure to high temperature. The properties studied are always measured after the temperature has returned to the ambient.
The term thermal endurance is used here to refer to tests performed in air, excluding any other influence or stress applied to the test specimens. Thermal endurance properties evaluated in different environments or at different Stress applied to test specimens require different test procedures.
In this International Standard, the study of thermal aging of plastics is based solely on the Change in certain properties resulting from exposure to high temperature for a certain period of time. The properties studied are always measured after the temperature has returned to the ambient.
Various properties of plastics change at various rates in thermal aging. In order to make comparisons regarding the thermal aging of different plastics, the evaluation criteria depend on the type of property to be examined and the acceptable limit value.
In the application of this standard, a practically linear relationship is assumed between the logarithm of the time required to cause a predetermined property change and the inverse of the corresponding absolute temperature (Arrhenius Law). For the plastics tested, there should be no transition, particularly a first-order transition, in the temperature range under consideration.
This International ISO 2578 Standard specifies principles and procedures for evaluating the thermal endurance properties of plastics exposed to high temperatures for extended periods of time.
During the preparation of this International Standard, the content of IEC 216 was taken into account. Accordingly, the terms and definitions and procedures described in this International Standard are in line with or identical to those specified in IEC 216.
Among the services provided by our organization within the framework of material testing services, there are also ISO 2578 standard tests. Do not hesitate to contact our laboratory EUROLAB for your testing and certification requests.
