The heat deflection temperature or heat distortion temperature (HDT) is defined as the temperature at which a polymeric material undergoes to deformation under a specified load. This property is fundamental during the design and production of thermoplastic components, and it is strictly correlated to the polymer crystallinity.To find the convection coefficient, note that the heat transfer from the cold surface to the fluid follows Newton's law of cooling. As a result, we have: \[q_{out} = h\cdot A\Delta T\] Here, \(h\) is the convection coefficient, and \(\Delta T\) is the temperature difference between the .SKZ144 Vacate Heating-distortion Temperature Meter.

Heat distortion temperature testing of plastics (HDT) is a standard test (ASTM D648 and ISO 75) used to assess the temperature at which a polymer, plastic or plastic composite specimen deforms under a given flexural load (fiber stress). The heat distortion temperature is also known as the 'deflection temperature under load' (DTUL) orThe Mean Annual Temperature Distribution over Earth: The horizontal or latitudinal distribution of temperature is shown with the help of a map with isotherms (i.e., imaginary lines joining places having equal temperatures, reduced to sea level to eliminate the effects of altitude.) Isotherms have three general characteristics: 1.
