BS EN ISO 1856:1996 is a British Standard that has been adopted as a European Standard (EN ISO 1856:1996). It is titled "Plastics - Determination of temperature of deflection under load - Differential scanning calorimetry (ISO 75-2:1993)".
This standard specifies a method for determining the temperature of deflection under load of plastics using differential scanning calorimetry (DSC). The temperature of deflection under load (often referred to as "HDT" or "heat deflection temperature") is the temperature at which a test specimen deforms under a specified load.
The standard provides guidelines for the sample preparation, test conditions, and calculation methods required to determine the temperature of deflection under load using DSC. It is important in assessing the thermal properties and performance of plastic materials, particularly in applications where the material will be subjected to elevated temperatures and loads.
Please note that standards may be revised or updated over time, so it's always a good practice to check with the relevant standards organization for the most current and accurate information regarding a specific standard.
