This section SN/T 1828 Part 7.

This section drafted in accordance with GB/T 1.1-2009 given rules.

The partial replacement of SN/T 1828.7-2006 "import and export of dangerous goods classification - Test methods - Part 7. compressed gases." this section compared with the SN/T 1828.7-2006, the main technical changes are as follows.

--- This document adopts some changes into the United Nations "on the Recommendations on the Transport of Dangerous Goods Model Regulations" (Rev. 17);

--- Normative references, the references, the latest edition of the normative document;

--- Appendix A "compressed gas Figure A.1 flowchart discrimination" in Box 2 "is 50 °C vapor pressure greater than 0.3MPa? Or whether at 20 °C all gas? "To" Are 50 °C vapor pressure greater than 0.3MPa? Or whether at 20 °C, 101.3kPa when all the gaseous?. " the partial modification of the use of the United Nations "on the Recommendations on the Transport of Dangerous Goods Model Regulations" (17th revised edition), within its relevant technology Exactly the same capacity with the above regulations.

This section proposed and managed by the National Certification and Accreditation Administration Committee.
