Executive summary:

This test using the procedures outlined in the ZCTC Study Plan for PCF2018-010-2,ASTM E 537-12and“APPENDIX 6 – SCEEENING PROCEDURES” in “UN, Recommendations on the transport of dangerous goods - Manual of Tests and Criteria” (ST/SG/AC.10/11/Rev.6)”.The exothermic energy of the sample was less than 500 J/g when the sample was tested by DSC during the testing temperature range. Therefore, CR SB37 does not belong to “Explosive substance”.

Description of key information

CR SB37does not belong to “Explosive substance”(UN, Recommendations on the transport of dangerous goods - Manual of Tests and Criteria).

Key value for chemical safety assessment

Explosiveness:
non explosive

Additional information

The exothermic energy of CR SB37 was 100 J/g, which was less than 500 J/g when the sample was tested by DSC during the testing temperature range (50-500°C). Therefore, CR SB37 does not belong to “Explosive substance”.
