BS EN ISO 11357-4:2021

What is ISO 11357-4 about?  

ISO 11357-4 is part forth in the multi-series of ISO 11357.  ISO 11357-4 specifies methods for determining the specific heat capacity of plastics by differential scanning calorimetry. 

Who is ISO 11357-4 for? 

ISO 11357-4 on determination of specific heat capacity is applicable to: 

• Plastic industry  
• Plastic testing authorities  

Why should you use ISO 11357-4?  

Differential scanning calorimetry (DSC) is a thermo-analytical technique, in which the difference in the amount of heat required to increase the temperature of a sample and reference is measured as a function of temperature. DSC is the method used to determine the specific heat capacity in plastic and is used in the physical testing of plastic and polymers. 

ISO 11357-4 helps you determine the amount of heat energy required to change the temperature to produce plastic. In order to produce high-quality and durable products, this standard can be your one-stop guide.
