Standard Test Method for Deflection Temperature of Plastics Under Flexural Load in the Edgewise Position
< div class=" SectionLevel2" > < p class=" subsec1 cdone2" > < span class=" Head3 cdone" > 1.1< / span> & #x00a0 This test method covers the determination of the temperature at which an arbitrary deformation occurs when specimens are subjected to an arbitrary set of testing conditions.
< span class=" note cdone" style=" text-transform: uppercase " > Note 1:< / span> & #x00a0 < span class=" note cdone" > Sheet stock less than 3 mm (0.125 in.) but more than 1 mm (0.040 in.) in thickness may be tested by use of a composite sample having a minimum thickness of 3 mm. The laminae must be of uniform stress distribution. One type of composite specimen has been prepared by cementing the ends of the laminae together and then smoothing the edges with sandpaper. The direction of loading shall be perpendicular to the edges of the individual laminae.< / span>
< span class=" note cdone" style=" text-transform: uppercase " > Note 2:< / span> & #x00a0 < span class=" note cdone" > The text of this standard references notes and footnotes that provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the standard.< / span>
< span class=" note cdone" style=" text-transform: uppercase " > Note 3:< / span> & #x00a0 < span class=" note cdone" > This standard and ISO 75-1 and ISO 75-2 address the same subject matter, but differ in technical content, and results shall not be compared between the two test methods.< / span>
