标准范围

This part of ISO 22007 specifies a temperature wave analysis method for the determination of the thermaldiffusivity of thin films and plates of plastics in the through-thickness direction. The method can be used onplastics in either the solid or molten state, and having either an isotropic or an orthotropic structure.The method covers values of the thermal diffusivity, α, in the range 1.0 × 10 m?s ＜ α ＜ 1.0 × 10 m?s.Measurements can be performed either in air or in another atmosphere, e.g. an inert gas, at atmosphericpressure or at other, reduced or elevated, pressures, or under a vacuum, at a variety of temperatures.
