CTL57 Header Bar                                     Logo-Chilworth-a-DEKRA-company_RGB.jpg                 


Determines the oxidising potential of a liquid to increase the burning rate of a combustible substance when the two are mixed. Specifically designed for UN and EC A21 regulatory testing.

Benefits   

  • Determines potential of liquid samples to increase the burning rate of a combustible substance when mixed to provide crucial transport and packaging / labelling data
  • Simple to use
  • Automated ignition / monitoring set-up
  • Test software / hardware: graphical display showing time vs pressure trace
  • Display of pressure rate of rise result between 100 and 300 psi
  • Ascii file logging of data importable to Excel (not supplied) for later data analysis

                DSCF0085a                                                                          Oxidising Liquid Test Apparatus

This test apparatus is designed to determine the potential of a liquid sample to increase the burning rate of a combustible substance when the two are thoroughly mixed or to form a mixture which spontaneously ignites. The liquid is mixed in a 1:1 ratio by mass with fibrous cellulose, heated in a test vessel and the rate of pressure rise measured. 

The testing is conducted according to the UN Transport of Dangerous Goods Recommendations Manual of Tests and Criteria, Test O.2 and also to Test A21 of the Classification, Packaging & Labelling of Dangerous Substances in the European Union.         A combined Time Pressure / Oxidising Liquids Test Apparatus (Model 025 - 057) is also available.
