标准简介
适用范围:
Heat generated by a reacting liquid encapsulating compound has the potential to cause damage to heat-sensitive electronic components. Degradation of the encapsulating compound has the potential to also occur at high temperatures. Proper selection of an encapsulating compound includes knowledge of its exothermic temperature to preclude damage to components.Since the exothermic temperature of a reacting encapsulating compound varies with the volume and geometry of material, it is essential that the volume and geometry be specified in any determination. Select the appropriate volume and geometry. The exothermic temperature is measured in sufficiently precise and reproducible form to allow for application evaluation, quality control, and encapsulating compound characterization.Exothermic temperature rise of two different volumes of the same material using the same geometry indicates the effect of volume. Materials may be compared by testing equal volumes of each material using the same geometry.1.1 This test method provides results that are related to the maximum temperature reached in a specific volume by a reacting liquid encapsulating compound, and the time from initial mixing to the time when this peak exothermic temperature is reached.1.2 This test method provides a means to measure the peak exothermic temperature of an encapsulating compound.This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. For specific hazard statements see Section 8.Note 1There is no equivalent IEC standard.
